The Skar Audio SK-M4004D full range class D four channel amplifier is part of the new mini amplifier series product lineup from Skar Audio. The SK-M4004D was engineered to be compact, but provide the power and reliability expected out of larger amplifiers. Featuring a high speed MOSFET power supply, and an efficient Class D design, this amplifier is powerful, reliable, and extremely versatile.
The SK-M4004D makes for a great amplifier in applications where space is limited but power cannot be sacrificed. In addition, this four channel amplifier features high level input connections for those installations that lack an RCA connection. In addition to the high level inputs, this amplifier also utilizes an adapter harness for the speaker outputs allowing for an easier installation.

Got the sk400 pushing four 6.5 fsx an the rp800 on the sdr 12 excellent products very happy with my purchases wish you guys had epicenters
Super awesome company glad I went with them for my car audio ordered on 4/17 and got it 4/21 I can’t wait to get it all wired up got 4 IX12s and a 1200 watt amp hopefully this weekend i will have it finished
Absolutely fantastic little amp, so much power for its compact size. If youre debating on buying this amp, quit debating and buy it asap. You wont regret it
I love this little amplifier. It really woke up my JBL mids and highs. Power is great and so is sound quality. It runs pretty warm but nothing really to worry about. You won't be disappointed.
To be honest I can't tell the difference between this and a class A/B this thing has a extremely wide frequency range from 10 hz all the way up to 41000! This amplifier is extremely clean at low and very high volume level's! Even using the high level inputs! 🥴🥴 Good little amp!
