SMALL AMP WITH FAN. WORKS GREAT

The following review is for T400X4AD, which is a part of the bundle you are viewing.

wow, this is a tiny amp and it pushes 100 RMS per channel at 2 ohms. Rockford also makes a mono amp the same size. Perfect for small trunks. I have both amps, crossover, and a lc8i under where the spare should be. Happy I got it. Sonic Electronix has a great deal.
