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

Awesome little amp. Very stable signal. Tuned with an oscilloscope to match my sub.

Have 0 issues so far, no overheating problems and powering everything very clearly

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. 💪

Sounds quality good power and ground screws sets backoff causing powerless only thing haven't tried is lock locktite in theads to prevent blackout of set screw

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
