The little amp the FC comes with (an s5 in my case) the one under the glove compartment.. is it only for bass for the front door speakers?

 

If you're talking about the amp I think you are... it's not just for bass, but it amps the front speakers. If you have aftermarket stereo equipment they should be bypassed and forgotten about, for they are crap.

 

Remove it or bypass it, as soon as you upgrade its worthless.

 

Yep, it's crap, when I got my car it was blown anyway, if you still wanna use the stock wiring, just unplug the connectors out of both ends of the amp and stick them togther.

 

aha.. thats why my door woofers aren't working!.. I was already doubting if there were speakers in the doors..

 

I was trying to use it for a little project and was only getting bass out of them, that's why I was wondering.. they have been out of the car for several years now
