I had to make a second purchase of an amplifier since the first one I bought needed parts and fuses, which disappointed me and I bought this option of open box excellent condition, unfortunately the same thing happened with this one, thanks to the chat assistance I had to go to a Besbuy store to give me the fan parts, for now it works well but they must certify well what they sell, since this AM was not in excellent condition and missing parts.

Didn't see it on the shelf, but one of the store salesmen stepped in and provided some help. I bought this for a Kicker Comp VR, 2 ohm dual voice coil. I wired the 12 for 1 ohm and let me tell you, this amp HITS! The gain is only set for 1/4 up and I am blown away, literally. Thank you for help.

Best amp I ever had. I currently have it hooked up to 3 10inch dual 2ohm kickers wired at 1.3 ohms and its absolutely too much for my vehicle Im now forced to upgrade the rest of my audio to match but my favorite part is how after a nine hour trip it wasn't very hot the quality doesn't meets the price its way lower priced than other quality amps like alpine
