First of all I have 2 12" alpine type-r subs which are ot installed and my car (2000 Honda Civic) already has nice speakers put in it by the previous owner. I like listening to alt. rock and punk really loud and then i like to listen to rap with alot of bass too. What type and how many amps do i need? or what else do i need....im new to car stereos thanks
well find out the rms of the subs and the voice coil configuration of them Ex(dual 4 ohm, dual 2 ohm) and then find an amp that would give them their rms you're probably gong to want to go w/ a mono block amp for the subs. As far as the speakers go try and find out what kind they are and get some specs on those as well. They are more then likely single 4 ohm and could probably handle about 50 watts. If that is the case then you could get a 4 ch amp that puts out about 50 watts x4 @ 4 ohms.
