I bought it from here, i installed it to power my 2 10" solobaric L5.
Total rms is 900 at 4ohms and it pounds hard that my friends could here it 3 blocks away..I was so pleased with this amp.

I have this amp hooked up to a power acoustik fubar and this thing pushes this sub to the max. i bought this amp at a local stereo shop and it was expensive but here in SE its a steal.

this amp is a powerhouse...MTX has always been a top performer in car audio, and they are only getting better. Especially now since they bought out rockford fosgate engineers..that is why the new thunder series amp are so much smaller than previous styles. This is the new Rocford Fosgate. I currently have this amp, and i must say that is a monster. I used to have a 1200watt boss amp but switched ecause it was going into protection mode too fast and wasn't giving me the power I needed. I have it hooked up to 2 10" shallow mount pioneers. Before they were barely being pushed now they sound like they are about to blow. This is an amp that is made to pound. Big sounds only

The 600xd amp is the perfect value and match with the MTX 5500 subwoofers.

I used to own this amp, but sold it to a friend for him to use for 2 5500 subs that he bought.

The bass control knob can be mounted by your CD deck for a convenient function of just turning a knob rather than messing with your after-market deck.

600 watts rms into 2 ohms? This amp has got some bang for it's buck. Not to mention it is a 1200 watt max amplifier, which would probably end up being a little bit more because MTX underrates their amps.

At the price listed here, it is a STEAL. Good luck finding it anywhere else for cheaper.
