Works at 1 OHM 800RMS and gets warm after a while
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.

Powerhouse!
I paired this amp to the pioneer subs (2 12") and it's way outperforming my expectations! Dual speaker outputs make hooking them up a breeze.

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.

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
