Overpowered

The following review is for JH300, which is a part of the bundle you are viewing.

I got this powering my JL 12w3 and it is sick. I don't even have the amp up all the way and it shakes my car. I could probably power 2 of these JL's with this bad boy.

Very loud subs!!!!!!!!

The following review is for JH300, which is a part of the bundle you are viewing.

I bought these subs thinking that they were going to be ok but they turn out to be great super good sound and they are loud but not too loud like other subs. you cant go wrong if you want to add more bass to your car but not over do it, to the point where you cant hear your self think.

Beastly Amp

The following review is for JH300, which is a part of the bundle you are viewing.

Have this amp running my 2 12" Kicker Comps and it kicks harder than you would think a 600w mono amp would.

Works like a charm!

The following review is for JH300, which is a part of the bundle you are viewing.

Installed this amp myself. Running 2 12" Kicker Comps in a 2002 Chevy Ext. Cab. They sound amazing with this amp. This amp produces very clean distortion-free power. I have the gain set about 3/4. The internal fan keeps the amp cool to the touch and you can't hear it running unless your ear is close to the amp. Pros, looks great, sounds great, bass control knob is def. a plus, the controls are very easy and user-friendly, the price can't be beat. The JH300 is easy to install and the allen key screws make for a tight, neat connection. I'm very impressed with it.

Good Amp Good Price!

The following review is for JH300, which is a part of the bundle you are viewing.

I bought this amp because MTX is a quality brand, and it had the right wattage for my needs......I bought a pioneer premier ts-1201 4 ohms and i dont know if i should have gotten a 2 ohm or what but man for being a shallow mount sub that sucker hits and 90% goes to this amp!!!! Love it
