From reading the previous messages, I know the Bose sub amp is located above the rear passenger weel. Has anyone tried to use an aftermarket amp to directly replace this amp so that it will be a bit more powerful (~100 watts @ 4 ohm) and does not require new wirings to be done. Or is the amp location too small to fit any aftermarket amp? If you know the way to open up the cup holder to expose the amp, please let me know.
What I am looking for is a cheap way to improve the sound and the bass volume without going though a car stereo shop.
Many Thanks,
Dr. Duan
I typed a long explanation and then the internet connection froze when I tried to submit it. I've done this and so here's the short version; as you move along the process I can provide more details. Before you start taking apart your car, though, I suggest you obtain a factory service manual.
1. No you can't access the Bose sub amp from the flip up armrest. You must remove the entire rear quarter trim panel (yes, its very large) and it entails removing the third row seats and storage lid.
2. Yes, there is plenty of room to fit a small mono-amp (maybe up to 6" x 9")
3. You will still need to run a power wire from the front of the car as the stock power wire is only 18-20 gauge (the amp, sans plastic case, is about the size of a double stack of playing cards).
4. Before you buy a replacement sub, be prepared to make a spacer ring of 3/4" MDF (bookshelving works) to accomodate the shallow depth.
Good luck and I'm sure you'll get a lot of help on this board as you go forward.
