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.

  • 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. ... show more
