Yep, at the amplifiers. I get the same 14.7 volt reading when they cutoff too.

I agree. I think the amps are toast. They're only a couple months old. I've read that Hifonics amps aren't what they used to be like back in the day.

I'm getting 14.7 volts to the amps. I have three amps going to a ground distribution block. One of the amps works, the other two monoblocks don't. I just installed a Mechman 400 Amp alternator and did a big four upgrade. I thought that would fix my issue, but it didn't.

I used different RCA cables, but I'll try and wiggle them to see if that helps. Thank you.

Hi Doxquzme, I just tried using the RCAs from my mids and highs amp (JL Audio JD-400) and both Hifonics amps still don't work. I think that the amps are faulty.

Thank you Doxquzme! I'll try those steps and will let you know.

I have two Hifonics BG 1900 amps. One amp is powering a 15" Sundown SA v2 at 1 ohm. The other amp is powering two 12" Kicker L7s at 1 ohm. I tested volts to both amps, and I'm getting 14.7 volts. Checked RCA cables and all is good. The amps do power on. They aren't in protect mode either...
