Not the performance I expected from a 12" sub, the amplifier seems to be complete garbage. The sound is muddy and never had any shake to it. It does not even come close to the performance of my Dayton SUB-1000 10" 100 Watt indoor subwoofer. At medium sound levels, the amp then started to distort heavily and gave me a headache in no time. If you are looking to add a bit of bass to your car, maybe this is an ok choice. But lets face it, you are not shopping for a little low volume bass if you are looking at 12" enclosures. This thing is supposed to rumble. Didn't work for me. I replaced it with the Rockford Fosgate P300-12 Punch 300 Watt and that just has the performance I was looking for, at honestly twice the price. I have not yet turned that thing up beyond it's capabilities, which is what I would expect from a sub of this size.
Would not recommend this product at all. If you are looking at under $100 subs, get a quality product of smaller size, you will be off better
