Just wondering...I did a search and didn't come up with anything.
Is there anyway we can upgrade to a more powerful amp and subwoofer while still keeping it mounted in the rear deck and stock wiring?? The stock is alright but I'm looking for something with a lil more kick.

 

r u talking about the stock 8 inch sub woofer???

and do u want to hook it up to the stock headunit
if yes then u can ....you just have to get an amp with speaker level inputs and then hok up the subwoofer to your amp and thats it

 

Sweet. Does anyone know what the rms is on our stock 8" woofer?

 

20. Haha...

 

Are you serious??
That is crap. I suppose it wouldn't matter while I was at it if I replaced the woofer too? Has anyone done this before? I know a bunch of people have put wooferboxes in their trunks and I'd like to but I really need to room for work stuff.

 

Come on, we need more responses. I'm looking at doing the same thing. I looked on Crutchfield.com and saw a few 8" speakers but I'm sure which one's will work. I hate not having a search option. I guess I'll have to make a donation...

 

im planning to do the same thing ....i would assume your best bet would be to get an 8 inch subwoofer and drill it in and get an amp that will power it and thast it nice clear soundsing bass!!!!

i can wait to do the saem thing

This is INCORRECT. You can't just use an amp with speaker-level inputs on a stock Bose system. You need some type of special converter. I would search, if I could... but you can probably find more info in the FAQ sticky. I think it's the PAC-OEM NISS-x kit, or something like that... (the kit & the adaptor are sold separately)

And if you want an 8" woofer to replace the stock one and fill in with some midbass, look at a woofer that covers a large range, like 30 Hz - 3.5 kHz.

$59 - Sony XSL836 @ 30 Hz - 3 kHz
$198 - Alpine SWS-0840 @ 32Hz - 2.5kHz

You get what you pay for.

You will probably need an 8" baffle from Crutchfield, since these woofers are not free-air rated. I could not mount my 8" Pioneer cause the hole was too small. (I get that alot when I try to mount things ) You need to cut the metal piece, or just buy an MDF board from Home Depot, and cut it to hold the woofer. The metal piece is crap anywayz...

Actually that is INCORRECT as well, you can just add female RCA outs at the radio itself. The run the RCAs to the amp.

Not on a 2k2+ with Bose... unless you know something I don't... in which case, please do share, Don! Unless there is some kind of kit available now, it would probably require a lot of "custom" cutting, hacking, and jacking.

Ok....
I'm just feeling more confused.
When you guys come up with an answer I'll get started.
Thanks.

 

how can u tell me you cant hook up an amp with speaker level inputs into the stock bose when b4 i bought my tv i had my subs hooked up to the bose thorugh speaker levels inputs into my amp and it worked perfectly

-J

 

cutting and hacking is how the pro's do it, and its as pro as ur gonna get anywhere else, why waste ur money on an adapter when u can just use the preamp signals from the head unit and wire them into rca's? its so simple and it sounds great

 

Did you amplify the full range, or just the sub frequencies? In other words, did you just tap into wires before they hit the sub amp, and amplified that signal into your own subs?... That can be done, but you can't "steal" a clean full-range RCA-type signal from the Bose head unit from what I hear.

And as far as tapping into a Full-Range speaker Level input: many here say it will cause damage to your Bose headunit...plus the quality isn't great at all. I've read quite a few posts. Then people just end up getting the adaptors and rewiring it anywayz... Of course, I can't search so I can't find any related threads.

nismos14: The 2k2 Bose does not spit out RCA preouts... (not the Navi one anywayz)

Please correct me if I'm wrong, people. This is information that I've collected from older threads regarding the 2k2 Bose (and Navi combo)

never said it has RCA preouts, the wirign thats there is a preout, its just not RCA preout, its wired preouts to the bose amp

 

Just to clarify my comprehension of this discussion, here's what I'm understanding:

OEM outputs from Bose (Clarion) HU are actually variable line level outputs.
OEM line level outputs work with aftermarket amps WITHOUT the need for a special adapter/converter.
OEM line level outpus can be easily converted to RCA outputs by cutting the output wires from the HU and attaching RCA plugs on the ends (a relatively simple process).

Now a few questions:

If I wanted, could I just tap into the signal lines going into the OEM Bose amp on the rear deck? I'm thinking I could use the existing/OEM signal wiring (instead of running my own RCA cables) and continue to also use the Bose amp to drive some speakers while simultaneously using an aftermarket amp to drive other speakers - Bose for rear and aftermarket for front.

Similarly, would this idea work with the subwoofer signal coming out of the Bose amp if I wanted to use the OEM signal but upgrade my sub amp and speaker?

Thanks!

 

I think #2 & #3 are INCORRECT. Someone should start a NEW thread with the Title:

5th gen - Aftermarket AMP with stock Bose possible???

Then the "experts" that have done this already will chime in and give you an exact answer, and a correct solution. Describe that you want a FULL RANGE amp setup, not just an amp for some aftermarket subs.

I think soundmike and studman have done this... but I can't search for their threads. Also, Kloogy had it done at a shop.

It would be great if Don (Pearl96Max) could weigh in on these questions . . .

 

yes the are all correct as far as i kno, all ur doing when ur adjusting ur volume control is adjust the level of the line outs

 

u could only use the bose amp to power the stock bose speakers. the reason being is that the bose speakers run at 1 ohm. there are no other automotive full range 6 3/4 speakers that run at 1 ohm. this being the case, the bose amps would put out minimal output because of the higher resistance in the aftermarket speakers

 

Not to be difficult, but I have a speaker measurement software and the impedance of the 2K2 Bose woofers in the front doors is almost exactly 2 ohms except for near the Fs where the impedance spikes way up . . . The Clarion tweeter is a 4 ohm unit. Also, using a higher impedance driver, such as a 4 ohm woofer, will present an easier load for the Bose amp to drive. The only problem with using higher impedance drivers is that they may have lower sound output depending on driver efficiency. Amplifier output usually divides by 2 as impedance goes up in multiples of 2; meaning an amp with 50 watts at 2 ohms may only provide 25 watts at 4 ohms. However, a more efficient driver can sometimes compensate for this disparity.

 

is the 2k2 wiring for the amp not use RCA's? They have their own type of wiring?

jasonb1982- where about is hegins, PA?

 

abs ur right, and maxtank ALL bose headunits use regular wires as opposed to RCA outputs

 

anyone have a picture of stock woofer with carpet off rear? im thinkin bout opening the stock woofer hole for a 10 or 12 inch woofer and mount a amp on side.

 

If you're upgrading the amp as well, ensure that your factory wires are the appropriate gauge. I usually say 0 to 200 watts use 8 gauge. 201 to 800 watts use 4 gauge. Anything over 800 use 1/0 gauge
