dont u think that piece of wood is too big, it like kills the trunk, other than that, it looks like it hits hard though, two amps! daym man

[NickyD240]

Aren't those amps going to overheat with no ventalation?

[hotcakes0007]

Dude the wood is made for a wall im going to put carpet and plexyglass to show off amps. i made it look like a wall and keep some of my trunk.

[hotcakes0007]

No there not most amps are made to handle worse

Aren't those amps going to overheat with no ventalation?

[S13xCrazy]

Great idea and execution!

I'll have to see if i cant do this for my MTX 9500.

I hate moving that thing tho, its a freakin beast

[OutToWinPAHC]

Were you rear ended? The floor looks a little banged up in the left corner.

But good install so far. And good choice on the amps

[hotcakes0007]

Not gona lie it probally was by old owner but that was also my doing with the MASSIVE HAMMER i used to take off the spare tirewell

cough cough get a 1000/1 for the sub sounds soo nice my buddy has one its loud as hell.

[s14tan]

Thats a nice clean setup. What are you gonna wrap that box up with?

[mchkc240]

I like your beat box

that's some gangsta sh*t

[GIJOE69]

wow the amps cost more than the car haha!...you ever thought about how you gonna use a rear strut bar? ?

[hotcakes0007]

ROFL LMAO True actually my sub and old high output gl box is more than my car not useing bar

[Tsukiko]

Seems to me that sub is underpowered with that amp, seeing as most amps marked 500/1 or something to that effect put out about 500 peak, not RMS (which is what you should be paying attention to), at something around 2ohms of resistance. I hope you have dual voice coils on that sub or that its resistance is naturally 2ohms. I personally dont like the sound of a 2ohm load though. Its a little dirty (used mostly for pure SPL), whereas 4ohms is pretty sweet sounding. Someone mentioned a 1000/1 rated amp. Kudos to that guy.

hey how about you post the specs of your sub and amp? what are you running for speakers in the factory locations, if any? any plans for acoustic treatment?

also- is that sub designed for a sealed enclosure? Im a huge fan of building a sub box to factory specs and calculating the port and tube size. The diameter of the port determines the frequency it accentuates, and the length of the tube behind it determines how much it is accentuated. then of course you get into the frequency response curves of the sub, amp, and deck....

sorry im an audio engineer... lol

[s14tan]

^dude....build me a box, have a feeling it would be kick as$ lol

[OutToWinPAHC]

JL amps are reated in RMS not peak, and they are rated at constant power output at 9-15 volts.

[hotcakes0007]

Lol belive you me the sub is far from underpowered box is sealed since i dont have the space for a ported box ill get full specs up in a little bit.

[IanS]

Looks alright, just dont get a flat tire.

[eazye2000]

JL amps are reated in RMS not peak, and they are rated at constant power output at 9-15 volts.

I'm going to say that it IS a true 500 watts RMS at 14.4 volts. The only amps that I ever remember being a 'true' wattage at 12volts are the old Earthquake amps. And maybe the old skool' Sound Stream.

I'm not going to get into a debate on this forum. Head over to the audio/video part if you want some 'technical' advice.

All-in-all, Looks like it's going to be a clean install, OP.

[CMG]

I don't know nothing about JL amps, but I've never seen an amp that has RMS watts in big writing. It's always Max. in big writing, then RMS written small somewhere else or on the bottom. Hope the op has some horsepower on his car, that audio set up would kill a stock ka24e.

[Tsukiko]

I'd say hes on the verge of needing an alt. I would also recommend a capacitor for the sub amp, since its not the only amp drawing power and needs a "buffer"

I was recently running an amp that was rated 1200 watts peak at 1ohm... although i ran it at 2ohm, about 800 rms, two 10" subs... everything seemed just fine until i added a second amp for a pair of 6x9s. then i could tell i needed an alt, and only cause the subs started to get boggy.

Yes sr20 is going in march JL audio can run at any impedence level. So 4 ohms or 2 ohms u can get the true rms which in my case is 500 Watts

[Tsukiko]

^dude....build me a box, have a feeling it would be kick as$ lol

haha i would love to, since i havent been able to put all the theory into practice as of yet. But seeing that you're in texas, and im in california...

and if i remember correctly, the W7 JLs are rated at 1000 watts, right?

SPECS!!!!

too bad you dont have a hatch, (at least when it comes to audio) it makes subs sound amazing.

[OutToWinPAHC]

You need to work on your math a bit RMS ( Rout mean square) is the effective ,voltage which is 70.7 % of peak. RMS the longest part of the waveform. That RMS voltage dived by the impedance of the speaker gives you the current then you take that current and multiply by the RMS voltage and you get your power aka watts.

So if your AMP is rated 1200 watts peak at 1 ohm the RMS power also true to 70.7% would be 848 watts RMS. Now double your resistance and that number is decreased by 50%. Simple Ohms law. So your true RMS power was in the range of 424 watts.

But depending on your wiring to the coils that power could be spread differently across the coils and the effective power could be something else.

I am a degreed electronics engineer and it’s a shame because a lot of people are lied to at the store and really think they have more then they really have.

Now when it comes to capacitors the 1, 2, 3 and 15 farad caps they sell are a miss interpretation of the true number. There is also a formula for determining the capacitance as well. In this formula time is a factor. These audio companies take this formula and manipulate it. The discharge rate of the capacitor simulates that of a rear 1 farad capacitor, but only for a nanosecond. Somehow they get away with claiming it’s a one farad capacitor. An actual 1 farad DC cap would be as large as the car and 1000’s of pounds.

DC capacitors in cars also tend to wear out rather fast due to the AC waveform caused by the alternator. Usually they don’t make more then 2 years.

[gripstr]

Nice i have the same exact setup on the s13

[CMG]

So are you saying all caps are worthless? What about for low wattage uses? Back in the day I found a cap at a military surplus store, and it stopped my lights from dimming from the power draw, but that was maybe a couple hundred watts.

[OutToWinPAHC]

Well they help, but the arent a true farad or higher. The store energy and when needed they discharge it. DC caps have a 3 year shelf life and a normal 7-10 in circuit life. The harder they work, they harder they wear out.

A cap on any car, system or no system would benifit from a cap, but plan on replacing it time to time.

The most important thing is to have a hormonic and supression filter. If I had the means to build my own ciruit boards I would build something for resale.

[Tulsa_S-13]

You could probably build your own active low-pass filter fairly easily, although the only problem to worry about would be how well it effectively eliminates the remaining harmonic distortions.

[Tsukiko]

ugh good point...

i'll have to brush up on my ohm's law and such, i hated studio maintenance class. lol.

[snoboard1500]

Simply sick
