Awsome amplifier!

Would buy this amplifier again and again. Would also recommend it to a friend. Clean sound separation and plenty of power.

good bang for buck

Decent little amp for what it costs. Puts out good enough power, I seriously doubt it does rated, but good enough. It's a little lacking in the controls dept, ie, no subsonic, no bass boost, fixed xover points. But it does what I wanted it to. Powering 4 6x8 components on the front two channels and rear is bridged to a 8" sub. It barely even gets warm. Pay attention to the wiring diagrams, for some reason Power Acoustik didn't follow industry standard here. Two of the wires w/black stripe are actually +. Overall, pretty pleased with it, small footprint, doesn't heat up, and puts out amazing power for the size of the thing. It is Class D, you do hear some more distortion vs a class A/B, but it's not much, and to me it's tolerable considering I didn't have room for this big of a class A/B.

Powerful little amp

This amp is very powerful for the size it is. I recommend it for anybody who has very minimal space and requires power to push your subs this is the perfect amp to have

Very good and cheap!

I got this amp because of limited space in my custom made amp box, and I didn't expect much, BUT the RZ4-2000D exceeded all my expectations!!!
Very powerful, clear sound, especially on the high volume.

Great Amp For The Money!

I bought this amp to power a pair of Kicker 6" X 9" 's and a pair of 12" Bazooka subs. All I can say is I was not expecting much but was pleasently surprised. Really brought the Kickers to life and only needed half gain. Decent sound quality and amp stays cool. Very compact and basic. Crossover is lacking features but most decent head units do the tuning. Set It and Forget It. If your looking for a good value, basic, compact amp.....This is a good choice.

GREAT on Harley Touring

powerful little amp - specs are nonsense, but on my '13 street glide it runs my MM651 Polks in the fairing and my Pioneer 6x9 in my saddlebag lids...
just take the end caps off and it will fit on top of the radio (Stock or Aftermarket). for a 4 channel amp, you cannot beat this one (in fact I think it sounds a tad better than the one I had before this one.

Great little amp!

This little amp packs a punch. I have it pushing four 6x9's and it handles them with ease. It stays fairly cool as well.

Power Acoustik RZ4-2000D

I bought this amp in trust that sonic electronix sales and promotes good quality products and they have delivered every time. This amp is incredibly small for the power that it is putting out and it does what it says it's supposed to do. I bought it to push my two precision power component speaker sets and it sound loud and extremely clear. Amp doesn't get hot nor does it clip or distort. This a great amp from power acoustic and I recommend for interior music installs.

Great little amp.

I wanted a small amp that could deliver power and not take up a lot of space. This amp really delivers.

Power Acoustik RZ4 2000D

I can only say that this amp is ok at best. It lacks several features, something more than just gain adjustments. Larger than what I had originally anticipated. There are other amps on the market for about the same price that are higher quality and features. if you're just wanting to put some power towards a couple of sets of speakers, this amp might be for you. If you're wanting to do more I would definitely go in a different direction.
