Thats not baller status. Step you game up son.

[Natedogg1701]

this is a system, cost me 2 back windows bkuz i was being a moron, and the amp has cost me 2 pairs of subs lol. u want info on the amp the model is in my sig, google it n check it out, its #1217 out of only 2500......and only person on here I've seen so far with a system I envy is W O T. he has 4 12's ina huge box, rediculous loud, he did a nasty job on it.

[fueler]

nala, i checked out that link you provided. there are a few types of jackhammers, you linked us to the stronger ones but if you look at yours, your pics correspond to the JH45 not the JH55

so they are 250 rms each which is a nice entry to mid level number. $100 each on crutchfield. So $200 for the subs, probably $40 for box and $150 for amp. (retail prices). Thats $400 just in parts, which leaves $100 as installation fee, (the wires alone cost the shop $10-$20) i'd say you got a pretty good deal overall.

But you know that shops pay wholesale and not retail, realistically they probably made $150 to $200 net profit off of you. Next time do research, pay wholesale or less than wholesale online or craigslist, and install it yourself to save $200+ in a case like this.

Theres no better feeling like being louder than somebody for half the price that they paid.

Anyways sorry for the rant, nice subs, enjoy them while they're new and under warranty!!!

[naladude911]

Yea, how do you blow subs, so I know what not to do lol. They sound the same, or a little bet better then my friend's system which he payed $1200 for. 2 10" Pioneer Champions with a 1000W kicker amp. Also, how do you know they are the less powerful jackhammers

[KyooX4]

Compare the pics.

[fueler]

you blow subs by underpowering them... that means trying to make them wang when you dont have the power, they will clip / distort and eventually blow. or if you have them wired wrong, or setup for the wrong ohms.....

[naladude911]

O thats good. There none of the above, so playing them at high volumes wont blow them

[fueler]

as long as you're not distorting or clipping. If the shop is good at what they do, then yes, you can crank it up with no problems. You should check out the GAIN setting on your amp, see what the shop set it at and play with it. The best setup is supposedly to turn off all synthetic bass enhancers (like LOUD, or bass boost) on the deck and adjust everything on the subs. But personally i find the music to be fuller on my Pioneer deck when adjusting all the synthetic boosters to a small degree.

Also, check the low pass filter on the amp, adjust that to how high of bass you would like to come through mine is at like 80 right now.

What deck do you have?

[naladude911]

Panasonic CQ3700Q. It doesnt have those bass boost controls, but subwoofer controls instead. AKA I can lower the sub volume, raise it, or turn it off

[Natedogg1701]

so you know, because i know so many people who do the opposite and destroy their shyt. if you have a seperate subwoofer volume on your radio then turn it up all the way, that way you can turn the gain on your amp down.

the gain knob on the amp IS NOT a volume knob like 90% of people think, it takes the signal it sees and boost it before it sends the power out to the subs, and as that signal is gained up it becomes less clean of a signal that gets sent to the subs, which in turn will clip and distort the subs easier.

so turn the subwoofer volume up on the radio all the way, or almost all the way, do this if you want to get a little extra uumph wen you listen to a certain song, or you want to show off. so once your subwoofer volume is set on the radio, gain the amp all the way down, and slowly turn it up and listen to it. (easier to have a buddy help you out leanin over the back seat while you listen up front) what you want to listen for as you gain the amp up is a distorted sound (sound of sub bottoming out or making odd noise as it plays, clip noises are very noticable and cant be missed, and smell too, a very common distortion sign is the smell of voice coil, will smell like something electronic burning and face of sub will be very warm, my eclipses do this, dont make clip noises i just smell voice coils), and you want to listen for the volume to stop increasing, as you increase gain the volume of the subs will stop increasing at some point, increasing gain past this point will increase distortion.

set the low pass frequency, LPF, at around 70 to 85 hertz, sealed box will sound very popy at frequencys above around 80ish hertz. and if you have a bass boost knob on the amp, this increases sound levels at a set frequency, well for 95% of amps it does, if you have a rockford amp like me you can adjust tht frequency but thts a whoooole diff scenario. any way, the bass boost increases power draw from the amp, has NOTHING to do with the gain, although you increase this so you can turn the gain down on the amp, so turn the gain down a bit, then turn the bass boost up a bit, but remember the boost is only for a certain frequency so it may sound good for one frequency, but not as loud as you'de like it at others, usually when i do installs i end up setting bass boost at about half way so i can gain the amp down just a bit more, less gain equals less distortion, less distortion equals cleaner/harder hit, and that increases sub responce and life.

and finally, yes most subs are blown because they are underpowered, when a sub is underpowered it doesnt hit straight forward and backward, it will twist and warp, this is because the entire magnet isnt being energised enough so the voice coil isnt getting equal magnetic power all the way around.so the sub twists as it plays, the spiders and surrounds wear out, and sometimes the voice coils will hit the inside of the magnets a,d wear down, break, or short out. but if your like me, you can overpower subs, which most people think they do but really dont know wtf they are talking about and they just underpowered them or wired them like retards. but the rms wattage on subs is most of the time a load of BS. i know this because im good friends with the store manager at local car audio/car electronics place around here, and we gave a pair of subs with 600 watt rms ratings about 750 to 1000 watts depending on the frequency playing. anyway we gave them good clean signal from a good amp and they played loud and clear, never clipped or distorted once, but we know how to install, wire, and tune systems. the place is called Sound Sensation. not like a raaco or tweeter or best buy where monkeys work nd mess up, this place has a solid rep and always gets the job done quik and correct.

sorry for the book, lol. but i hope this info helps, it'd be a shame for your new system to be ruined because its not set up correctly. feel free to ask any questions you may have.

[naladude911]

Thanks a ton for the help, I hope you didn't write all that lol. Umm, the owner of the shop and I spent a good 30 minutes adjusting everything, so that it sounded crisp,not distorted, and yea. He said, don't f*** wiht it hahah

[fueler]

the rms wattage is most of the time a load of BS.

true that. Sony Xplod is guilty of this - they make amps that say 1000 watts but really barely push out 100w!!!

[naladude911]

So i looked at the amp, and I do have a bass boost button. Its been off the whole time

[longhornsqx4]

......and only person on here I've seen so far with a system I envy is W O T. he has 4 12's ina huge box, rediculous loud, he did a nasty job on it.

That was actually 4 15's!!! I was talking to him earlier and he said hes making the switch to 18's.

Nala- you coulda got alot better equipment for the money

[audtatious]

Underpowering a sub will not blow it. Using an underpowered amp and pushing it to a clipping point can blow it.

[Natedogg1701]

umm..........not to be rude but YES underpowering a sub WILL blow it, i already explained why but foot notes explanation, lack of power will to a sub will not send enoigh power to efficiently ennergise the entire magnet equally, therefor the sub will not play straight forward and backward, it will warm and twist, which wears out surround, spiders, and damages voice coil since it hits the inside of the magnet. and when i mean this type of underpowering, i dont mean a string good amp turned down, i mean a weak cheap amd that is cranked all the way up trying to power too big a sub, i dont mean big as in sixe i mean big as in what it needs for power, it will distort the signal to the sub which is also an underpowered distorned signal, i only deal with peoples system bs almost everyday of the week so i know a thing or two, and i have a nasty system of my own that is comprised of all quality components.

and that was 4 15's?!?! wholey crap thats rediculous, what type of subs are they? and going to 18's, dam thats gunna make some noise. he must have a lil $$$ to play with. lol you and him should check out a guy named Steve Mead, hes all over youtube. he has a suburban or an escalade with i wanna say 8 FI 18's in the back, the long version of the truk, the entire back behind the two front seats is 1 HUGE ported box. and he has 2 Rockford fosgate T15Kw's.......these are big boy toys, biggest car amps EVER MADE, 25,000$ each, make 15,000 wats of power, he also has seven 350 amp alternators under the hood, lol. theres a video where hes 35 feet from a store with plexyglass windows, and the windows are bowing 6 inches in both directions! thats effin loud.

sony isnt lying about the 1000 watt claim, they arent just explaining at all when the amp will make that power. one its with a perfect 14.6 volts constantly at the amp, and its not at the low sub playing frequencys that most people who buy them use them for, it requires more work for an amp to play a lower frequency, the 1000 watt claim is under whatever sony considers PERFECT conditions, and at a higher frequency. so technically they are not lying, but they still sukk none the less. lol

and naladude911 your welcome, my first system was a pioneer single 10 band pass box, with an old mtx sub (cudnt tell what type), and some back woods no name amp. butfor the time it was great in my 1994 frod E-350. lol, i had bass! lol. after those i had a pair of dual 10's in the bandbass box they sold as a preready product, and i went from that same no name amp, to a boston accoustics GT-20 (awsome little amp), then to an alpine mrpm-500(another awsome amp). then i got the pathy and i bought 2 eclipse, 2005 model sw7124's and a ported box, first hoocked them up with the alpine amp, boy was that a rediculous difference, the i got my first rockford amp, best thing ever, it was the old power chassis style befor the current one, the T3002, claimed 300 wats bridged, actual power tested, on average 1200, thats rockford power and no lie, tested it with some1 who is now a good friend , hes the manager at the car audio/electronics i go to, rock solid rep, the main installer is one of the top 100 in the country, hes effin good. then i got the beast i have now for an amp, rockfords 25th anniversary power 1000, only 2500 of them made (i have #1274),its a 5 channel amp capable of doing 1 ohm at every channel. I cracked that box and blew those subs with this amp, got the subs warrantied and also the box warrantied, because subs were under warranty from date of purchase i got the 2009 model eclipse's equal to mine, the new 6210's (also called aluminums), and used value from old box to put towars new Gforce 116 ported box, blew out a rear window with these subs, and cooked those subs at the same time (i was messin around and seein what they could do) so i now have my second pair of those subs a,d dont be stupid like i was then, they arent under warranty anymore lol, and cant afford new ones. mind you my amp is always gained completely down, my radio has extremely high pre-amp voltages so i send a very strong signal to the amp, i have a full gain range to play with if i ever got stringer subs, hehehe, when i cooked the old ones i had the gain about 1/4 to 1/3 of the way up.

and finally a question naladude911, is it a bass bost button or a knob?

[Qxxx4]

Nala, nice setup! your going to experience every song in a whole new way. I cant stand hearing music in stock systems now, i end up laughing at my friends.

Natedogg, you have the same taillights as me!

as for the installing yourself...its so true....I got my subs/amp/box for $140 used of craigslist, still pumpin hard a year later, and if the setup gets stolen...wow..$140. Sure its not a sick setup like natedoggs, but i get a real clean sound that my friends all find impressive. (2 10" clarions in a sealed box, """"1500W""" (super quotations) boss amp that im shocked hasnt died.) The pride i get that i did it myself is immense, its not worth it to pay someone else, it was so much damn fun figuring it all out and it really wasnt hard at all.

Not to be rude but I've been messing with car audio since before you were born....+ another 7 years.

Using an "underpowered" amp in itself will NOT blow a sub. If that were the case then simply using the volume knob at low levels will cause a sub to blow if it received _any_ distortion from the signal. The problem with a "weak cheap amp that is cranked all the way" is when overpowered it can create a square wave (clipped sine wave) which is seen similar to DC current and the speaker cannot deal with it, thus you get cooked VC's. But, not in all cases will this even cause a sub to eventually blow. Running a 50w amp to a sub with 500w thermal power handling will simply lead to crappy sound but you could play it clipped all day from that amp and it will never be able to heat the 500w subs VC's enough to cause damage.

EDIT: Here's a good reference I found for you since I'm sure you won't believe me.... http://www.bcae1.com/2ltlpwr.htm

[naladude911]

So am I safe then with not blowing my subs?

[audtatious]

A 1000w amp with two subs that have 250w RMS? You can absolutely blow them sukkers up.

[naladude911]

But there not underpowered?

[audtatious]

Underpowering won't blow them unless you start clipping. With a 1000w amp you have 2x the amount of power the subs can handle so I suggest you adjust your gains properly.

[naladude911]

Il take a pic of the amp settings

[audtatious]

Follow these instructions:

Unregulated power supply:http://www.edesignaudio.com/gains_video.php

Regulated power supply:http://mobile.jlaudio.com/supp...d=143

To determine what voltage to aim for is determined in part via the amp load. Are you running each sub to a separate channel or is it a bridged output? If bridged, are they connected in series or parallel? What model is the lanzar amp?

For example....let's say it's 500wpc (1000w total), you are running each sub to a single channel of the amp and the sub is 4ohm. The rated WPC of the amp is kinda thrown out the door since it's double the RMS of the sub which can only handle 250wpc so we will target this setup for 250wpc....

Using this site to determine the required voltage for 250w you see your target is 31.6v: http://trussinme.com/Apps/audi...t.asp

Underpowering a sub will not blow it. Using an underpowered amp and pushing it to a clipping point can blow it.

http://www.bcae1.com/2ltlpwr.htm

I like your play on words there. But you are right. In a nutshell, you can't blow subs by underpowering, if the case is that you are listening to classical music at low volumes in a G35. But if you drive a man's vehicle and you have a sound system, it is assumed that you are wanging it. So yes, underpowering + wanging = clipping = blown subs (sooner or later)

that website you linked us to as proof, is quite ghetto and it's basically just some hater talking about how everyone else is dumb because they are wrong and he is right. Not an informative link whatsoever, i'd delete that one out your bookmarks if I were you.
