Really impressed!
I had this amp (still do just not hooked up) in an 85 prelude on a set of 6.5 type-r coaxials and a set of 5.25 type-r components, and it performed awesomely! Rated at 150 rms @ 4ohms per channel, I believe you cannott get a better amp!
Though it doesn't have any preouts, you don't really need any because most subwoofer amps have them and that's what it should be connected to! Love the stackability and self-polarizing quick connects! Only hang up is the adjustments are not readily accessible because of the cover plate.... but you should only have to set your amp once!

found this helpful.Nice amp
I have had this amp for a while now. Originally I had some issues with it shutting down into a protection mode. I never really figured out what was causing this. I asked around, had others look at it, no one could figure it out for sure.
After messing around with it enough I found that adjusting the gain so my max playing volume was at a lower volume setting on my head unit seemed to fix the issue entirely.
I do not think the amp was faulty and am certain it was not an overheating issue. I have used many different amps in the same configuration and have only had this issue with both of the Alpine amps I have used.
Aside from that issue it has been a nice amp. The small size is great, and the stacking would be great for tight space installs. I really like the polarized quick connects for the speaker outputs as well.

As title says, its a quality amp, with great looks! i have a concealed install on my FJ Cruiser, so looks do not matter so much, but i love how its made, the ease of install and option of being stack-able.

found this helpful.Best amp you can buy for your highs and mids
I have this amp running 2 type S 6.5's in the front and 2 type r 6.5's in the rear doors and they sound crystal clear... The main reason to buy this amp is because it's class d which means it's more efficient and gives your vehicle's electrical system less strain while supplying more power to your speakers. No brainer purchase.

found this helpful.Great Amp
I bought this amp in December and its powering 4 infinity 692.9i 6x9s and 2 39.2cf 31/2s. Ive had it on full range and get incredible sound reproduction. Ive have had it on high pass as well with the recent addition of my alpine mrpm500 and ppi pcx 124 single 12" and the highs are incredible. I own a 06 charger and I mounted the pdx4.100 upside down in the rear deck 8" sub cut out and it looks perfectly at home there. Awesome amp, definitely worth the money. Even in the Florida heat, in a trunk it still powers everything great.

Nice amp, good sound quality, but no pre-output, and lacks features found on similar priced amps. Also cheap plastic on sides, and caps are also plastic.

found this helpful.Great Amp, Nice compact design
This Amp not only looks good and is discreetly compact, but it produces some awesome results. I hooked this up to some Alpine components it it sounds amazing. I definitely recommend this amp to anyone looking for something to push 2 sets of Alpine SPX-REF components, since that is what I have.
The only down side IF I had to pick one would be accessing the gains. There is a door that you have to remove in order to get to them, and you have to use the right size Allen wrench in order to remove the door.

I search around for months, talked to dozens of people, and looked hundreds of amps...and this is the 2nd best amp I've found, the only amp that takes this amp down is the MTX Thunder Elite 1004, and the 604 elite is the equiv of this amp.
this amp, i got it last week, hooked it up a few days ago, even though i was still waiting for some more parts, new speakers primarily, but i hooked it up anyhow and tweaked around with it to see what it could do on my old speakers and with in the first day..it completely blew my rare speakers :-s
the rating on this amp is amazing, 150 is the nominal RMS, i had it only about 60% on the gains when the old speakers blew, and only about 50% on the head unit. the sheet that came with them, stated 180 watts RMS at 4 ohm, was tested stable back when it was packaged. mine was packaged almost 2 years ago, but none the less, damn good amp.
keep in mind that the possible peaks per channel can reach as high as 216 watts. At 60 amps at 14.4 volts. You'll be hard pressed to find a better amp, and the 2 ohm 4 ohm ratings are amazing, the ONLY amp on the market that even offers that, and in such a small footprint.
I took off some because I felt there could of been more tweaking on the knobs that could have been added, granted the head unit will do most of that in my set up, but a 3-band equalizer will really not do this justice. the lay out of the inputs is designed not for just speakers but for any set up, so keep in mind your wired and what they are when you install them, they are marked as channels, not rear front, left and right as normal 4 channels are.. I managed to mix up all my channels and have a hell of a time figuring them out :P
