Working on my next car related project, two pairs of 4 channel Rockford Fosgate Powerr 300 clones.
I got my hands on one of these amps about 12 years ago from a drug dealin pimp daddy in Lakeland, Florida (where I grew up). I thought with the excellent Navy training that I was getting, a repair would be simple. didn't work out like that, instead I reverse engineered the whole thing, had 8 new PCB's made and started with all new parts.
The relatively bare board...

All this crap, and then some, will eventually make the three new amps.

I already have two in the car, these three plus one of those will be the four that go into the new heatsinks.

I found these from a seller on Ebay. They prompted me to go ahead and make some more amps. Heatsinks were the hardest part of the project to source. These badboys are just over 2 feet long. I plan on giving them the mirror polished finish and maybe some sort of logo that i still haven't designed, but you can be sure it will match the theme of the car.

I've got two built and mounted on the heatsink. I haven't polished it up yet, just hit it with 0000 steel wool to remove all oxidation. I'm making the endplates and bottom now.
What you're looking at are two old school Rockford Fosgate Power 300's mounted on one sink. Strictly by the numbers, that's 8 channels producing 50wrms each, or in bridged mode, 4 channels at 150wrms each, or 4 at 50, and 2 at 150, you get the idea. Of course, those numbers are waaaaay underrated, and don't even consider comparing them to the class D amps that are on the market today. These are the original bruisers.
