Bose 9 speakers system

[dc]

How does the system sound in the coupe? Do I need an amp and a sub to get a nice deep sound? I'm not the type that blasts their speakers loud, but I enjoy some bass even when the volume is set to medium volume level.

The Bose has its differences in sound quality between the stock unit. It sounds fairly rich and definitely has a nice sound to it. Full of bass, plenty for me. It sounds great when turned up. If your more of an audiophile than you could purchase replacements that would further suite your taste but its definitely perfect for the average user.

Sound system sounds great to me, but if everyone you pass must hear what your listening to you might need some upgrades.

Couldn't have said it better myself. I just don't understand why people spend all of this money on systems that can be compared to a 5.0 magnitude earthquake.

I enjoy bass, and that's one of the weakpoints of the Bose system. The mids are pretty good, but the lows are pretty bad. I added a sub and amp and it sounds a lot better. i'm not looking to blast the sound, but just have full sound in the car.

[LongBeachCoupe]

Ive heard of some sort of bass limiter or something on the car.. or some sort of volume control that we cant control, it controls itself!What did you put in the trunk? I just left my 2 12s in my mustang bc they wont fit and allow me to bring my golf clubs!

[ChiLLaXtodaMaX]

I think there is a bass limiter and it definitely doesnt sound as good as an aftermarket headunit, but it sounds much better than the stock Bose bass.I got a MB Quart RA2400 amp and MB Quart 15" in the back. 2 12's might be too tall for the trunk, but the 1 15" fits.

[LongBeachCoupe]

a 15?? damn... i was thinking maybe a bazooka tube i can move around....

[ChiLLaXtodaMaX]

lol yea. It was moved in from my last car. I would really get something smaller, but that'd mean spending more money. I already have 2 Kenwood 12's just sittin around.

[Plastics]

I have the 3.5SE Coupe with the Bose system.

After listening it for a while, there doesn't seem to be a lot of stereo imagaing (ie: the system sounds like a mono....)

I try covering up the centre dash speaker and it helps a bit.

Don't get me wrong, it is pretty good for a factory system, but is it bit lacking in terms of good solid base and clean /clear defination.

Maybe some nice Alpine R speakers and a poweramp and sub would help.

Would appreciate any input, pleae post away.

I am gonna get flamed but whatever. The BLOSE sound system they sell in cars and people keep saying is good enough for the average user is garbage plain and simple. Take an RTA into your car and get a good image and see it for yourself.

Car manufacturers build for cost not quality and the marketing guys take care of the rest.

There is no need to build an explosion causing sound system BUT if you make long commutes and or spend excessive time in your vehicle then you might consider getting all your soundstage upfront where it belongs.

You dont go to a concert and then enjoy it sitting backwards.

If you plan on keeping your car for a good bit consider getting door build outs or kick panel build outs. Alpine Clarion Pioneer and whatever make good electronics, stay the hell away from their speakers LOL. Focal, MB quart, AVI, Scan Speak, Dynaudio. Those are speakers.

If you want a cheaper alternative then use cheaper equipment. The point of my rambling is that nearly ANYTHING you do will be better then BOSE. BUt dont touch the Stereo or door skins if you are not keeping the car. Door skins cost a few bucks dude.

Thats my buck and a half.

I have to totally agree with mosswalker. Bose car and home audio is nothing more than good marketing. Don't get me wrong, it's not horrible; however, it's not that good either. Their home audio is way overrated. Actually, it's not overrated, it's just marketed good and people think they sound great. But stack them next to Definitive Technology speakers, or even Klipsch for that matter, and they don't have a fighting chance.

For car components, I prefer Boston Acoustic and Polk Audio. Focal and Dyn are great speakers, but I personally don't like MB anymore. I feel their tweeters are a bit on the harsh side. But yeah, anything decent in the aftermarket will pretty much sound way better than ANY OEM stereo.

[ChiLLaXtodaMaX]

agreed.

Bose blose! Their car audio is slightly better than their home theater audio. I have Ascend Acoustics at home and most likely paid less than a Bose 5.1 system.

I just ordered my coupe the other day (3.5se). How tough is it to wire in a sub to the factory bose system? I remember it was kind of a pain on my RSX.

[LongBeachCoupe]

It isnt a difficult install, but theres some sort of Bass limiter system...

[audtatious]

The bose headunit has some style of "notch limiter" built in. As you turn up the volume it decreases bass and midbass output to keep the speakers from being damaged. Initially, in my Maxima with the Bose 6CD headunit and replacement speakers, I added a PPI pre-amp so I could turn the bass gains up to counter the headunit. It worked OK, but nowhere near as well as a replacement headunit. Since then, JL Audio has introduced the CleanSweep that will recondition the output prior to amplication so you can keep the radio.

[ChiLLaXtodaMaX]

the CleanSweep is pretty expensive, or so I recall. You might as well add in your own aftermarket HU

[Seraph321]

Except replacing the head unit would really suck if you have the tech package. Could you get something that still integrates with the touch screen??

[audtatious]

Not and clean up the signal path. You can interface directly with the HU and get RCA out's but without the cleansweep the bass will lower as you turn up the volume

i am taking the door skins off this weekend and making a start on my doors. I will post pics as i go. Going to have a 3 way up front. The build out will be easy. The X-over is going to be a pain in the ***.

Just ordered the Peerless 8 woofers and scan-speak 4" mid from Solen.ca . Debating what tweeter to use though. Ribbon or ring. Tough call. Definetly posting pics now, this is going to look sweet.

I just went to see my 2.5 S with premium package yesterday at the dealer (picking it up thursday). Checked the sound system and it did disappoint me a little, I was expecting much cleaner sound (maybe some adjustments to the bass/treble will fix that or maybe it was just the XM channel he put on.)

I didn't test the bass but based on everything I've read here, this will definitely be an upgrade I'll consider in the future.

Which sub-woofer brands would you guys recommend? I had a Infinity amp and subs before, liked the sound but not powerful enough at low volume.

Thank you all for the much needed info

[shift_mikey]

Does anybody have a listing of specs of the speakers? (ie, size, location) I'm curious if there is anything on the internet about locations of each speaker, size, method of removing and installing etc

[mosswalker]

Anyone need a set of peerless 8's ? I heard dual 6.5's in a Jap' Maxxima 2003. Plenty of quality Bass and very sharp defined attack on Kick drums.

As for the limiter, yes it is on the amp unit. A lot of signal modification crap inside that cAMP.

What section should i put the build into when i start it on Saturday? Pictures and such.

Just make a thread here in the Altima forum. Looking forward to seeing your project.

[rjdmmfl1]

I asked my local install guy, he said that there are currently no diagrams or information on the speakers...he stated that the car companies usually don't release this info, the way that info is released is when someone rents the car, and has a technician tear it apart and put it back together...I'm about to take my car up to the shop next week and have the entire audio system gutted and replaced with the Pioneer Avic z2 unit, aftermarket Rockford Fosgate interior speakers, Rockford fosgate Power 1000 amp, and 1 Rockford fosgate T1 12" sub...I'll post info on the speaker locations, sizes, etc. as soon as I get it!

[generic808]

If you have the standard stereo system, it's running 6.5" in the front doors, 3.5" in the dash, and 6x9's in the rear. I replaced all mine with aftermarket gear.

Oh yeah, just to let you know, the factory speakers are 2 ohm Blau's. So, if you're planning on replacing the speakers and keeping your head-unit, use 2 ohm'ers, otherwise you better amplify it

[dangeris]

When I added a sub to my 1999 Acura CL 3.0, all I did was tapped into the speaker lines BEFORE it went into the amp. I think I used a PAC-NI35?. Anyways, it's an adjustable line converter. RCA to the amp and added the Infinity Kappa perfect. Doing it this way I retained all the factory functionality while adding fullness to the sound. Can this also be achieved in the coupe? is there an electrical shematics floating around or that someone has?

[shift_mikey]

Generic, thanks for the information!! What brand speakers did you go with? did you keep factory amp/head unit? How much better does it sound?

Any advice/walk throughs on how to remove each speaker?

The only decent 2 ohmers I found were the Infinity Reference series from this model year and the Kappa series.

To remove the door panels, all you have to do is wedge the door from the bottom corner and then all the way around, down and outward. Removal of the entire door panel is NOT necessary. You only need to remove 4 or 5 retaining clips which sanp in and out. Pull panel out to allow enough space to work with. Just to let you know, the factory 6.5" is a Blau mounted in a special "cup" which is much larger than 6.5". You will have to drill holes for the new speakers because they will not plug and play. I just drilled 4 holes and used self-tapping screws. There is no factory harness adapter so all you have to do is splice the wires, shield and crimp. Then just reverse the process.

The rear deck, you just lower back seats and I believe there was 6 retainint clips in place. Remove those and then there the plastic deck which is snapped in place. The 6x9's drop in perfectly, so no hole drilling is required.

Same goes for the dash speakers. You just have to use a flat head and wedge out the grill. Be careful not to scratch your dash though, I put a little nick in my grill Remove speaker and just splice in new one.
