I just installed this amp and its very small, but packs a lot of power! My birth sheet said 136 rms on the front channels and 142 rms on the rear channels. The box said 100s at 4 and 2 ohm. It has that constant power technology similar to the BDCP amps from Rockford. I have 2 sets of t1 6x8's in my ford five hundred, and I'm pushing them with 50+ watts over what the speakers are rated at (80rms) they sound great with no distortion. The clipping indicator works great! It makes setting your gains properly easy as hell. No engine noise. Clean signal. Tons of power. This amp is worth the price.
