Awesome little amp!

Have this tiny thing pushing 2 Sundown Audios e8v3's and they sound so clean! I'm impressed with the power this thing does in a tiny package! I would recommend it.

Works Great

As expected, this is a great amp! My only complaint is how small the power & ground holes on the side of the unit. It was tough getting the wire that came with the package to stay in those (think the wire is 8 guage). Otherwise, it's working great.

Phenomenal Value!

I got this amp to power a single 10" Earthquake dbxi at 4 ohm which is 400 rms. This amp was a massive step-up to the previous amp which was under-powering the sub a great deal. This amp made the sub come alive. I have no immediate plans to swap the sub as it's plenty loud for my extended cab truck but when I do I'll get a sub that can take the 650 rms at 2ohm. Considering the price point you'd be foolish to pay twice as much for another amp. This thing runs cool, stores easily as it's quite small in footprint, and puts out plenty of power. Highly recommended!

outstanding

I ordered this sub to power one of the pioneer pro subs and it easily powers the 600rms sub. Also this amp is so tiny!! The only issue is it says the recommend wire gauge is 4 gauge, but honestly the inputs on the amp are early big enough for 6 gauge. Buy this amp!!

Awesome little amp!

Perfect small amp with decent power at an awesome price! Love the speaker level inputs with sensor trigger, which saved me $$ when installing into my factory Audi stereo.

Really nice !

This amp has provided good, clean power for my sub-woofer for about 1 year. It has survived the Jacksonville, Florida summer heat, in the trunk of my black 1999 Mazda Protégé, with no troubles at all !

What I have:
amplifier for sub-woofer (Precision Power i650.1)
sub-woofer (Earthquake Sound DB10)
passive radiator (Earthquake Sound SLAPS-M12)
sealed sub-woofer enclosure (Belva MDFS12)
receiver (Kenwood KDC-X898)

Precision Power PPI i650.1

I have this amp installed in my truck pushing two JL 10W0v3-4 subs. They are wired up for a 2-ohm load and this amp makes the subs sound great. I know that I am pushing the power handling of the subs but I am willing to risk with the idea that I keep the volume levels along with the gain down. Two issues I have with this amp: First off the power terminal is located above the ground. I love the compact design but not a fan of the power and ground connections being so close. The other concern has been voiced here before with the smaller than 4 gauge opening for the ground and power. My amp kit came with 4 gauge wire and I had to order some 8 gauge power wire because I was really concerned with trying to shave the 4 gauge down. I was deeply concerned with any stray strands and the ground located directly below the power.

Overall I am happy with the small footprint that allowed me to hide these away real well. Just take your power wire design into consideration before buying.
