[QUOTE="vibebreaker, post: 3147187, member: 578460"] my car has 2 front door speakers with tweeters and crossovers and 2 rear deck speakers w/ tweeters and crossovers. i'm pretty sure they're wired in series. (alpine type-r 13s fronts alpine type-r 17s rears) i'm looking to buy an amp and a subwoofer (just a single 10 or 12 inch) i was thinking about the alpine mrp-f450 ([URL="http://www.crutchfield.com/S-KgVIfW...50&i=500MRPF450"]http://www.crutchfield.com/S-KgVIfW...50&i=500MRPF450[/URL]) will that be sufficient to amplify everything? it's a 4 channel amp so i put the driver side speakers on one channel, passenger side speakers on another and the subs on 3 and 4 right? also my alternator only puts out 80amps and im guessing not at idle..
