Recently, I've went all out and grabbed me a hold of a bunch of Polk Audio equipment. At first I wasn't too interested in gettting a nice stereo system, but I figured that I spend a lot of time in my car and I love music, so why not. Installing all of this stuff was quite enjoyable for me. Here is a list of everything I bought.

Polk Audio C500.1 x 3 - 500 watt Monoblock amplifier
Polk Audio C400.4 x 1 - 400 watt 4 channel amplifier
Polk Audio C300.2 x 1 - 300 watt 2 channel amplifier
Polk Audio MMC6500 x 1 - 6.5" component speakers
Polk Audio MMC690 x 1 - 6x9" speakers
Polk Audio MMC525 x 1 - 5.25" speakers
Polk Audio MM2124 x 2 - 12" 400 watt subwoofers (800w peak)
Polk Audio SR124DVC x 2 - 12" 700 watt subwoofers (1400w peak)
Absolute 1.8 Farad capacitator
Rockford Fosgate, Street Wires, Kicker and Stinger wiring

For my set up I used everything listed above except for the 2 channel amplifier and polk momo 12" subs. I sold one of the subs and gave the amplifier and remaining subwoofer to my brother. I did the install myself and built a fiberglass enclosure for the two subs and made my own amp rack.
