I was wondering what I should go with to power these two sets of components...

I was thinking about a couple of options, but I want to stick with JBL because I already got a 600.1, so I want all my amps to match.

P80.2, runs like 40 watts x 2 at 4 ohms, get a couple of these or....

P80.4 only 40watts at 4ohm x 4(I don't think enough power) or

P180.2 and a P80.2, the P180.2 runs like 90 watts x 2 at 4ohm

I will need some sort of combination of these to run these components cuz I got a Alpine CDA 7995 without an amp built in so I can't use the deck for amplication of the rear fill.

Also, anyone think 3 amps is too much on a 135 amp alternator? I think the 3 amps combined will draw like....almost 120 amps....

thanks
