Bad a** lil amp 4 the money!!! Pushin 6.5's, 5.25's, and 4x6 plates! Will buy another 4 5's n plates tho!! def worth the money!!!

Good value amplifier!

This amp has a great sound, small footprint, and low energy consumption (class D "digital" amp). It is a no frills amplifier that puts all its power into sound (not flashy lights and other bells and whistles). This amp is a great value for the money. The highs could be a little more clear, but for the price I don't think there's a better digital 4-channel amp on the market. Pioneer did a great job with this one.

Since it's a new amp, I can only guess on its durability based on Pioneer's track record.

The only downside I can see is that the amp has the "old style" connections for power, ground and speakers, not the newer, more convenient allen wrench connections. Presumably this was done by Pioneer to save money, passing the savings on to the consumer. That, with some lack of definition in the high end, is the only reason I ranked it "4" instead of "5". In actuality, I'd rank it "4.5" if this were an option.

Great Amp in a Small Package

This amp replaced a much older, larger, and less powerful Pioneer 4-channel model I had been using. I continue to use 2 channels to power my front (component) speakers, and bridge the other two channels for a trunk mounted sub in my 09 Civic Si.

Another advantage is how much cooler it runs. This isn't really a requirement for me due to where I've mounted it, but for those that are considering mounting in a confined space like behind or under a seat, it could avoid a melt down (had that problem with a Sony amp).

It took a while to "balance out" the gain and high/low pass filters for optimal sound and performance, but I'm really pleased with the results.

Great Amp

I have this amp installed with a Pioneer double din 4200. I have two sets of the Infinity Kappa Components. The sound is incredible. I had each wired to one channel, but the amp is REALLY under rated. I already blew two sets. Luckily there were replace by Infinity. Now I have a set wired to one channel so I am only using two channels and they still sound great at only half the gain.

Big performance, small package

If you have space or power requirement considerations, this amp is the solution. It draws less current than comparable output amps, and is small enough to fit in tight spaces. Very clean sound, adequate power to drive 4, 2 ohm speakers, nicely overcomes road and exhaust noise in my Corvette convertible at highway speeds with the top down. Great value.

Great Buy!

I bought this to power my Polk 6501 component speakers and the 651s in the rear. So far so good, amp is very compact and powerful. The polks definitely scream hooked up to this thing, thank you SonicElectronix for a killer deal.

Good To Go

An excellent out of the box, plug-n-play kind of amp. Very compact, stealthy. It's sturdy, durable and you can easily swear on its build quality. Above all, looks good too. Performance? Well, I used a couple of amps and this one didn't need any kinda tweaking, as if it just understands what speakers it has to drive.

Better than i Expected

This works great, have been useing it for 6 months now and am very pleased.

Perfect for speakers

This powers 4 polk audio speakers in my camaro. It is a huge gain over the factory setup. Can't go wrong. Don't waste money on more expensive ones.

great little amp

I’m using this amp to power a set of pioneer 5-1/4 component speakers in the front and a set of pioneer 6 x 8 three way speakers in the rear door of an 02 Ford Escape. Overall, I am pretty happy with its performance alongside a powered 10" sub. I don’t know how it would sound without the sub or if you powered a sub off it too. It is a great fit, out of the way in the cargo area of my SUV. Seems pretty durable too. I was moving a large metal chair that had shifted and hit the amp pretty hard. It put a little gouge in it but no other noticable damage.

One issue I have had is when I connect my ipod to my pioneer head unit, there is a very low but noticeable white noise. Like the sound when you (use to) start a cassette tape. I can’t think of any other explanation. It may be the cable, head unit or my crappy older ipod but I didn’t notice the noise until I had the amp in. I have had a little trouble tunning amp to my speakers but only because I mostly don't know how. I am a diy'er and don't like paying people. I think I got it pretty close to its best sound. Again, that's according to my ears. All in all, this was a great upgrade to my sound system that sounds great to me. Very clear and balance sound.
