Rockville RXD-M3 4000W Mono 1-Ohm Car Amplifier, High-Speed MOSFET, Adjustable 12dB Crossover, LED, Remote Sub Control, Perfect for Car Audio and Subs

I have this amp powering 2 Rockford Fosgate P3 12’s and impressed with power it Produces!

Anything is better than my 200 watt amp before, BUT this amp surpasses my expectations! Not only for its function, sound quality, and price but the thinking behind each and every connection; power inputs and speaker outputs have a set screws that are at about a 45 degree angle meaning they securely lock a wire in place AND you don't run the risk of grounding out your tool on the chassis IF you like to take risks and not disconnect it beforehand. Read through the reviews on its performance; I am not going to bore you with my speaker setup or technical data since it works great for me and from a lot of the reviews; it works great for them and that's what I based my purchase on. So you keep reading reviews if you want or just get it! In the meantime I'm going to go for a drive....

The amp does push great power for the money. I had a single alpine type x 12" rated for 1k dms at 1 ohm. While this amp seemed a bit lacking compared to my Rockford fosgate 1000.1bd, it wasn't bad for the money.But heres where I'll say to stay far away. Rockville has some awful quality control. Without music playing, no wire shortage, no fuses blowing.. The M3 amp just started smoking. Yes it took a year of use, but it was burning itself up from an internal shortage.Rockville first told me in an email, it's under warrenty. And now, says it's been over a year and out of warrenty. If I'm willing to pay for repairs and shipping, theyll fix it. So they went back on their word.If you go on YouTube, you'll see EXO and other youtubers recently having a problem with the K9 subs. Not being up to their cea rated power. Rockville replied saying his tests are flawed. Fairly unprofessional.The M4 amps have a very similar issue. Where people would get them, work for a while, and just stop working. That's what happened to mine. Not pushed or even used that often. And smoked, without even anything playing.

Running 1ohm load to 2 10" Power Bass dual VC subs. Amps does not get hot and has good power. Still tweaking trying to adjust it to not sound too harsh for the regular tuner but still hit hard on bass cd's. Might have to install the bass knob to fix this issue although I've never experienced this with any other install I've ever done. I replaced on old PUNCH 200 that had a damaged gain knob. Was not impressed with the Rockville fuse block that came with this kit, the cover falls off too easily.

This thing is amazing. It's nice to finally be able to get something that has decent R. M, s, everything else lies. This thing straightforward and tells you what it puts out

Just installed unit in my 2010 f250 hits way harder and better sound quality then my old Rockford 4000 watt amp good product easy tuning have been running a Rockville RXD-F30 Micro Car amp separate for my speakers for about a year all around these guys make a good product would buy again

Got it powering 2 2500 watt skar subs and haven’t had a problem with it yet going one one year

I love this amp. It hits really hard and has all the protection from not making it blow out. Louder than my 800.1 kicker and that blew in 3 days. It stays on hitting pretty good barley goes in protect. Ive went through alot of amps, autoteck 2500 amp meanmachine, the alpine 450 mp, also the power acoustic 2500 and this one is better than all them bar none. Steady at 1 ohm is a major plus for me. Im pushing 2 gothics. And I've blown mtxs 10s 6000 series, alpine type r, almani, kicker 12 comp r, kicker 10s comp r, and the german red 12s 1000 watt.

Say 4000w and 2000rms got certificate and its only 1000 rms now cant return it not happy
