tons of power

Purchased the full phantom system (amp,5 1/4" and 6x9's) They handle full volume thrash metal easily and the music sounds fuller than it did through the infinity system they replaced. Take the time to adjust each channel, its worth it! And an install kit makes it simple to install.

FALSE power rating!!

This amplifier has nowhere near the rated power. We tested and it was capable of 55W per channel at 4 Ohms and 165W on the bridge at 4 Ohms.

Great amp for the money

I purchased 2 of these amps about 6 months ago. And installed them in my boat on the passenger dash side dry storage. Fed via 0/1 marine fiberglass wrapped fireproof wire getting power from two dedicated house group 29 batteries isolated from the start battery on a digital charge relay ballast system. Audio comes from a pioneer BEH-X8500HB with tripple 4v RCA outputs. The speakers are 2 pairs of Polk MM651UM performance marine speakers. And the 2nd amp feeds a 10" bazooka and a 12" 1200w in a sealed box.

The cockpit hits 138dB and it is clean audio no clip to 40' out at 87dB. Every one that has seen or been in my boat over the summer so far says it is the cleanest sounding stereo that they have heard. The bass is a solid pound for an open air configuration and it sends trimmer ripples out from the sides of the boat.

These amps are great value for the $$$ and deliver a great sound for the money. They are the perfect product for my application. I will be using them again in future applications. I am overly happy with these amps. They compare to amps I have had in the past that were 5x the cost.
