This amp is part of a complete audio system I put in my 2001 Jeep Cherokee XJ. I'm using it to bump up the power to four Polk Audio db651s speakers mounted in the stock locations. I set the cutoff at 60 and am running a RF Punch P300-10 for the bass. It has its own built-in amp. The Polk Audio speakers sound great so the amp must be doing something right. It's mounted behind the Kenwood Excelon KDC-X300 in the dash. Out of sight, out of mind.
Great little amp!

This little amp packs quite a punch when you're short on mounting space. Going from stock head unit to an aftermarket always ends up sounding flat and tinny. I had purchased a larger amp to address this, however my plans to mount it under a seat ultimately turned me off.
I bought this unit and installation was quite simple. No running wires from the engine bay and running a ground wire to somewhere on the floor. Just need RCA cables, radio wiring kit, and crimps. 90% of the installation prep was done before opening the car door.
The size of this amp is great! It fits right behind my head unit with room to spare. I definitely recommend!

This little alpine amp is Amazing! For the money and the convenience there is nothing out there that can compete. My piece of advice is use this amp bridged at 90 watts rms x 2. Using the 45 x 4 is ok for increasing clarity but will only give you a small power boost over your head unit. At 90x4 this amp comes alive and can compete with some bigger wired amps in power and clarity. I definitely recommend this amp for a small component set and it will bring it to life.
It has its pros in cons in my opinion.

This is definitely an improvement to a stock head unit. It sure does pack a punch after tapping into the stock head unit power and ground, as described in the manual. Some maybe skeptical that splicing into the head unit power will be sufficient for an amplifier but I think it supplies plenty of power.
I replaced the stock speakers with JL audio C2 series and had the gain on this amplifier at nearly 20-25% and it was quite loud.
Great amp for tight spots!
I was replacing y 2002 WJ Grand Cherokee's Infinity radio, which meant I could not use the factory amp anymore. I was going to run the speakers off the Kenwood head unit- then I found this Universal Power-pack online. I patched it into the factory amp's wiring harness under the back seat, even re-used the factory power/ground wires. I ran two sets of 11.5 foot RCA cables for my signal from the Kenwood to the amp because I wanted a nice clean signal. I already had full range 6.5 speakers in the front doors (was not using the old stock dash speakers anymore). WOW it blows away the original amp, nice clear sound with enough bass to shake my seat (jazz/blues/rock) from the four 6.5's in the doors. I can't believe I didn't have to sacrifice cargo space or run huge wiring for it! Nobody even knows it's there- perfect!
