anyone have any suggestions. i have Diamond audio all the way around. need a good 4x channel amp. any sug gestions on what to get these babies bumping

 

What diamond Audio are you running? what's peak on them?

I am a huge fan of Alpine Amps. I would suggest the MRP-F450 (4x75) or the MRP-F550 (4X90) (these are 4 ohm ratings)

There are other amps out there that give out higher advertized output, but the signal isn't as clean. When I spoke to a Diamond Rep, he said that these would be perfect for most of their product line.

 

I have the JL 4 channel amp. I love it and its 110 RMS at 2 ohms and 75RMS at 4 ohms. I picked mine up off E-bay for 200.
