car fixed.. new question

just wanted to tell everyone my car got fixed and thanx for all the advice it really helped me through the whole process.... now that my car is back i am back to experieimenting of course:wink:.... my new question or questions are... one my back window works on and off... sometimes it works sometimes it doesnt... any ideas? can i fix it myself?

my next question is i have two 10" subs that i was to put in the back but do not want to get an amp. is this even possible? can i hook my subs up without getting an amp? and how?

thanx!

The window is a problem in the motor itself. There is a thermal limiter that will fail intermittently (does the window work when it's cold out and not when it warms up?). Subs need more power than a stock stereo pushes, so there's no point to installing them without an amp. They also need a crossover to limit the frequencies sent to them because high frequencies will damage sub-woofers. If your car has the Bose stereo, there is a separate factory low frequency amp that may be powerful enough to run 2 10"s, and you could connect them through the rear speaker wiring, but if you don't have Bose, you'll need an amp.
