hi this will be my first post to the forum i just wanted to say hi to all and i need your help i am just starting to do work on the stereo of the car and i want to know if this is possible: it has the stock Bose stereo still, stock head unit and all now it has a sub woofer in the rear deck is it possible to unhook that sub and use those live wires to power a after market sub this will be temporary i haven't tried this yet and i want to know if it will damage anything thanks.

much appreciation

If you are disconnecting at the sub, you are post-amp, specifically, post-Bose amp. Bose has a nasty habit of running anything but typical impedance (4 ohms) on their speakers. In my MX-5, the Bose amp runs at .5 ohms. Stupid.

The first point being that you are very likely to mismatch the impedance of the amp and your aftermarket sub, possibly causing damage. If you don't have damage, you probably won't get much sound at all since the Bose amp is not very powerful and is likely at 2 or less ohms.

 

First of all, welcome to the forum!

i HIGHLY recommend using a dedicated aftermarket amp to power the sub. when i installed my 12" Kicker L7, just for shits and giggles, i did exactly what you are asking. no sound came out of the sub. i now use a 1200W Sony Xplod amp.

 

Fixed, and you should take my advise as well...

 

yes u can jus use this .... http://www.sonicelectronix.com/item_...OEM-HON20.html

 

I believe this is to ADD an aftermarket amp. The OP wanted to power a subwoofer with his factory Bose unit. The factory unit probably has something around 200 watts...and i believe thats peak. You wouldnt be able to power a subwoofer(at least very well) with that, and as other people mentioned impedance issues.

 

Yea but quality and sony products should never be in the same sentence especially their amps so I think thats why he worded it the way he did lol. Yea and just get a nice mono amp. Hell they can be had brand new for $100, check out hifonics or audiopipe. Good low budget amps.

 

I would definetly not recomend you to do that remember that output for the stock sub in the rear deck was made for that stock bose sub no more watts are gonna come out from that radio just go get an aftermarket amp you will be better off and would get greater sound.
