Skar Audio A U D I O Compact Full-Range Rms Mosfet 4 Channel Car Amplifier (SK-M4004D,400W)

Good value, lots of power. make sure you mount this amp with a gap as the fan is located on the bottom. It worked a lot better for me once I gave it more room to breathe. It gets hot and will overheat if you do not do this

Pleasantly surprised with this amp. This amp replaces my old 4 channel amp and mono sub amp. It is running my 6x9 front door speakers and 6.5 rear door speakers along with a 10” pioneer subwoofer. This amp is a bargain for what it’s capable of doing. The sound is nice and the build quality looks great. I would buy this amp again.

This Skar Audio SK-M4004D amp is a beast in a small package — delivers crisp, distortion-free sound and plenty of power for all four channels. It runs cool, fits anywhere, and really wakes up your speakers. Perfect mix of size, strength, and quality. 💪

definitely outputs the power advertised, and sounds extremely clean. Only thing I don't like is the small subwoofer wires on the output harness. I feel it's too small for the rated output

As someone who has been into car audio for several decades I was very skeptical that this amp would perform for this low of a price. I read reviews and watched YouTube vids of amp dynos and this amp is legit. It puts out more power and sound than my alpine amp I replaced with it and for a fraction of the cost. It’s definitely worth the money and it performs very well. I haven’t had any problems with it so far and it hasn’t shut down from heat or anything either. I’m pretty impressed and I think you will be too. I’m definitely recommending it and if you’re on the fence about it, go for it.
