Powerful amp at a great price

I purchased this amp and installed it nearly 2 months ago. It never shuts off or overheats and I drive more than 2 hours every day for work. Installed in my trunk, ran a 4gauge power cable that I trimmed slightly to fit, and run it hard for hours at a time. Recommended if you are using for personal enjoyment. Note that the instructions are not clear on how to wire the remote power on. You must connect this to the white wire on the remote bass level potentiometer.

Small package with a lot of volume

I have been looking for a small amp because I don't have a lot of extra space in my 2000 GMC 2500 Ext Cab - and wanted a digital amp because i was concerned about heat. It has been 20 years since I had an amp that wasn't factory and so far I am thrilled with this product. It has only been a week since i installed it so I can't really comment on durability but I am truly impressed with the amount of power this puts out.

Currently it is running a set of Infinity 6.5 components in the front, Infinity 4 x 6 door pods, and two Infinity 10 subs built in a down firing enclosure that I made.

I am not an audio file but this system sounds awesome and is perfect for my eclectic tastes. I am still working to get the gains set properly and play with the high and low pass filters. I will have to do a little more research on the best method to do this by ear and not trigger the protection circuit which I have done twice.

The only issue I had during the installation is that the amp will only take an 8 gauge power feed and I had already ran 4 gauge in anticipation of getting another amp and that the terminals screws were Phillips head screws. Not a big deal and for the price I paid I am not going to complain.

Just to be complete this amp's source is a Pioneer Avic D4 (pretty old) and I usually listen to an Ipod or bluetooth through a Motorola TK30 - provides Ipod and Bluetooth.

rz5 2500d

Nice and compact. I'm no expert but I don't think it can push 2500 watts. I have it hooked up to a pair of rf shallow mount 10 r2... Non the less it sounds good. I'm happy for the price.

This thing will power your whole system and the thing is tiny. I am running NVX speakers, front components in front and 6x9 in rear and a NVX VSW104 subwoofer. everything runs good. i just don't believe that the 600RMS @ 2OHMS. I tried the box on a 400rms kicker and it hits harder.But for the price, this is a good buy for a all around system and easy to hide. oooo and it just gets warn with 2hrs of play.

The amp seems to been well built but the wire connections suck.Set screws for wire tightners? When you tighten the screws on to small fine wire the screws cut the wire.These wire connectors need a rethink.

big power small package

First of all its small. It could in any ride. I'm running pioneer D series components up front and orion HCCA components in the back and it pushes them loud and clear. The sub channel is most impressive. I was running 2 JL 12W6 V2 subs in a sealed box wired at 4ohms and iwas amazed at how hard it pushed them. Love this amp! Especially for $150. Also a friend has a JL 5 ch he paid $550 for and he was impressed with this amp.

Power Acoustik RZ5-2500D

This little amp is probably a bit overated in wattage but is very clean and runs very cool. Been running it for over a month now. The small guage wires are a little annoying but i have big fingers so it just takes a little longer to fumble my way through it. The instruction manual needs to be in a larger font as I had to literaly use my cell phone to zoom in on it to see what the diagrams were but being made in north korea, i guess they need to save ink for more important things like propaganda...overall, great amp for the value

Unlucky guy

It seems that I am the only unlucky guy who has bad experience with this amp. I am from Bosnia and beside all difficulties (Bosnia is out EU; had to be patient with shipping...) I decided to get this 5-channel amp. It's specification and customer comment were OK. Finally, after almost two months I got it. After installing it with professional installation kit I realize that subwoofer and one channel do not work. Other three are OK and sound seems correct. Still it is in warranty period but I am not in favor to use it because it would be another frustration for me (at least I should wait for two months to have some feed-back). I wish other customer who buy RZ5-2500D to have less bad luck than I did...

No problems

Does what it says, first install I've done alone and no problems yet. Runs cold never heats up too much I don't think, so definitely a D-class.
Only powering a sub through one channel at the moment, will be wiring all speakers to it soon.

IMPORTANT: the remote turn on wire to connect to your head unit is the wire that's connected to the bass control knob. Plug the bass control knob thing into the amp, find the 'white?' wire (I think it's white) and connect that to the remote wire you should get from a wire install kit, super easy.

I can't vouch on how much this thing actually powers, apparently they over rate it, but it's powering 2 10' pioneer shallow mount subs in the 5th channel pretty well.

The tuning knobs are easy to turn and such, almost too easy, but they don't move so it's good.

Works pretty good

The power and ground wires are really close together for some reason on this amp so care must be taken when hooking it up. It is a good amp for its class rating.

Nice Amp, but the ratings are way off

For the $$$, yea, nice amp. But I put an oscope on this and this is not getting anywhere near the RMS ratings. I even used a power source at 14 volts and at best it was doing 65 watts x 4 and right at 250 on the mono. I wanted a cheap system in my hunting vehicle. Overall for money, can't complain, but I don't understand how these companies are stating numbers taht are nowhere near close. I thought there were electronic standards?
