Amazing Amp

This amp is an absolute monster at putting out wattage! I was surprised with how small this thing is too especially since it puts out so much! The only problem I had with this amp was that the description says it fits 0 gauge although there is no way that it fits 0 gauge, I had to buy special adapters to compensate for this although not a big deal in the long run!

Great Amp

This amp puts out more than it is rated, the birth sheet on my amp said 1300 watts rms. Overall it's a great amp for the money.

Excellent amp for the price

I have this amp pushing 2 Kenwood shallow mount 12-inch subs in my truck. The birth sheet on mine said 1300 watts even, and I have no doubt it puts out that much power. I also have a Prime 400-4D running my Kenwood components in the doors. Maybe they don't have some of the ultra-cool, competition-level amp features found on more expensive amps, but that's not what I bought them for. I like how this amp sounds, and I don't intend to enter any sound competitions anyway. I can't even turn the system all the way up and stay in the truck; that's how loud it is. And even in 95-degree Florida Panhandle weather, neither of my Prime amps get very warm. I would definitely recommend this unit for anyone wanting to add some serious power to their system without having to spend large sums of cash.

lots of power for the price

My birth sheet said 1,313 watts at 1 ohm. Can't really beat that for the price. Small amp with a lot of power. I recommend upgrading your battery though. My lights dim a lot on my stock battery. It accepts 4 gauge wire but I would recommend running 1 gauge wire to the trunk then use a 1 gauge to 4 gauge distribution block so you will only have about 1 or 2 feet of 4 gauge for more juice to the amp. It does not have a built-in fuse so you need to buy a fuse holder.

Awesome Value

I purchased this for a quick replacement for a 5 year old MTX amp that went out; I was very surprised how great this amp sounds with my 2 Rockford Fosgate P3SD412 subs considering how inexpensive and small it is!!!

Works Amazingly

This amp blew me away. I replaced my POS kenwood kac-9105d amp with this and the difference was night and day. I've owned the amp for 6 months had have had no problems with it. It never overheats, even in the 90+ degree heat. My only complaint is hooking up the power and ground cables. 1. The power is on the right when it is traditionally on the left. I almost blew the fuses the first time I hooked it up and since the fuses are internal, I would've had a completely dead amp. My friend did this with his amp and he had to buy a whole new amp. And 2. Fosgate recommends 2-gauge power and ground cable for this amp but I can just BARELY fit my 4-gauge wire into it. It takes me forever to get the power cable in correctly. Not to mention i have the amp mounted on the back of my sub box out of sight, and the terminals are faced inward towards the box! How stupid is that? So not only is it nearly impossible to fit 4-guage wire into it, but you can't see what the hell you're doing either. And they made all their amps like this! Honestly, they could have done things better and made things a lot simpler.

Second To None!

This is a very powerful amp in a very small package. I paired it with two Rockford Fosgate P3's in a bandpass box. I would definitely recommend it for those wanting the most for their money.

I only have one complaint...the website states that this amp accepts a 0/1 gauge wire for power, but it doesn't. 4 AWG is the largest size that will fit.

Overall it is an excellent product at a very low price.

No Regrets

After 6 months I'm happy with this every day. It can deliver without a problem, and the "remote punch" lets you adjust the level on the fly--couldn't live without that now. To make it happy, I upgraded my alternator and battery and added a capacitor, ran a two gauge cable to split into fours (for this and the P400), threw in ANL fuses, and now I'm happy. Real happy.

amazing amp for price

Not many amps are this cheap but yet still very reliable. I got one of these pushing two kicker 15s at about 600 watts each and they bump. I am very
pleased with the amp and would buy it again if I had to.

amazing buy

Bought this amp to push 1 kicker 12" l7 @ 2 ohms but then I got rid of that sub and got my hands on 2 kicker l5 15's running @1ohm. This amp does a lot more power than it says it can.. By far the best purchase I've ever made. Rememeber people, YOU GET WHAT YOU PAY FOR! If you buy this amp, you will NOT be disappointed!!
