Previously I had a Crunch amp and it gives the alternator whine when I press on the accelerator. Tried many ways to fix it with capacitors and better grounding but it can only be fixed by turning down gain all the way. After changing to this, it sounds really clean even with the gain being turned up by default, despite having reused all the old power and grounding cables.

Très facile d'installation. J'ai un 10" 400 watts et l'amplificateur le prends très bien. Ne deviens pas trop chaude pour l'instant. Reste à voir sa longévité à long terme car je ne l'ai que depuis 24 hres. Arrivé en même pas 24 hre.

Some scumbag stole my sub woofer power amp out of my Honda Pilot. This was a great replacement and paired perfectly with my new Pioneer car stereo. Good a and fast delivery. Way cheaper than the audio shop wanted to charge me for a smaller lower powered amp. Just fit under the passenger seat with no obstructions.
