So far so great

I’m new to the car audio scene, but I’m a big fan of these amps. Outgrew my taramps bass3K and went to the Stetsom 5k (decent amps) but wasn’t super pleased with it so I returned it and purchased this MD 4K. These bigger subwoofer amplifiers love power… I’m running oversized agm primary battery, zero gauge OFC big four upgrade, 350 amp Apex alternator, and a 3.5 farad capacitor. Feeding the amplifier with dual zero gauge OFC power cables and dual zero gauge OFC grounds.

Power hungry

Puts some true power down. Make sure you have an extra battery, good quality 0 gauge wiring, and high output alternator. It really pulls some power.
