    • Good product will buy again
Had the amp wired up to my double skar 5000w loaded pack, pushed out plenty of power and sounded amazing had the wipers in my jeep bouncing an inch off of the windshield lol. I definitely recommend because it wasn’t breaking the bank while still pushing out power

So durning normal play the amp shut down under a normal load . Powered into protect. We cycled the key off and back on, and the amp produced a high pitch squeal and back into protect. Me being a 30 mecp level one certified audio installer, went back to the amp, unplugged the RCA inputs and dialed all the gains down. Again cycling the key, the amp squealed and went into protect. Considering I used to work for American bass, not just in sales but also as a equipment repair tech, I decided that there a problem. So after disconnecting this amp, I opened it up. Upon opening I noticed right away that the tamper seals were previously split. Once I removed the cover, the pictures you see is what I found. This was not a brand new amp as advertised but a referb as you can tell by the solder points I am pointing to. When hifonics was made by API (audio products inc) these were unstoppable. The quality now...... I'm not going to comment. The pics speak for themselves. Fyi the output transistors part number hy4008w are 1.50$ a piece. I'm going to rebuild this amp not using these poor quality components. Just so you know this is what you are getting. It's a shame also that the quality of these I would use to chock my wheels with now as opposed to having being able to say I got a brutis 4k. ... show more
