Single amp or multiple? Could use advice

[johnsahl]

You can do with the built in fuses, so you are good to go.

Dont worry about overpowering, you simply adjust the output on the gain switches on the amplifiers, thats standard..

I was also wondering if i should be worried about over powering my door speakers? The front door 6.5" JBLs hold a rating of 60 watts rms each while the rear 6x9s are 100 watts rms each. I was really just looking for something that could give the rear 6x9 speakers a little more juice but unfortunately for the front speakers its a lot more. I understand earlier somebody told me not to worry about this. The 4 channek amplifer is rated for 600 watts rms and is 150 x 4 @ 2 ohms

150x4@2 ohms usually means about 75x4@4 ohms, which will be plenty loud and clean. Adjust your amp for the front speakers with the rear turned all the way down, then bring up the rear gain until you get a nice rear fill. 75x4 will match up well with your 500 watt amp on a sub.
