Works well and is great for my dule kicker 10” comp vr at 1 ohm and pushes them at 800RMS but does get warm used it for 4 months till I got 2 JL 12”s and had to get a bigger amp but in short works well and would recommend.

Consider yourself warned, this thing is junk!
This thing is junk! Or should I say “was” junk. First off, from the beginning the remote bass knob never worked right. Lots of static and electronic noise unless you positioned the knob just right. It was so bad that I ended up disconnecting it and just adjusting the bass through the head unit. Now for the bigger problem, IT DOESNT WORK ANYMORE!!! I’ve had this thing for less than 6 months and it’s fried! Called pioneer and they want me to pay to send it in. Not happy about this thing at this point. Buy and use your own risk and don’t rely on the warranty if you do have issues with it.

This amp work and functions perfectly to its stated ability. Was super easy to install with 4 gauge wire. Bass control works amazing. I’m pushing one 12” at 800w rms and it’s amazing, i could blow my sub easily. Highly recommend this amplifier especially for cheaper options.

Amazing for my JL audio subwoofers

Good starter amp.
- Probably better for speakers than a sub - Sleek metal build that stays decently cool - Not as powerful as other amplifiers, but still good power. - Small, and can fit in tight spaces - Worth the money as a starter amplifier

Not worth the money
Only lasted one year in a car I don’t even drive often. Overpriced junk

Terrible
It came used beyond belief, rattling inside, stripped screws. No customer service. Terrible all the way around. I’m about to return but this upset me so bad I just went with a skar 1500. And if you’re running 2 sub set up like me it’s better anyway. Skar has much better numbers
