Hey i'm new here. I am pretty knowledgeable with car audio/video, but this one has boggled my mind. I am running two 12" Kicker Comps on a Hifonics BXi608 amp. I have had this setup for awhile now but the other day it went into protect mode and I can't get it out. I have removed the in-line fuse for a day to try and reset the amp, that didn't work. I checked all of my wiring and everthing is fine with that. Can anyone tell me what is wrong?

Hifonics amp went bad, maybe? probably. is it still in protect with the subs unhooked?

Chances are your amp has one or more shorted output transistors. You will need to have all outputs on the side that has the shorted ones.

I have no idea what it was but I took out my inline fuse again during class today and when I came back from class and put the fuse back in they worked fine and have since then. Thanks for the help though!

I thought I had it fixed.. it did it again today.. It's like an off and on thing.. sometimes when i start my car they work, other times they dont... i just put a new battery in and tested me alternator.. I have no idea what it could be..

Disconnect the speakers and the RCA cables from the amp. Using a volt meter verify you have a good power, ground and remote connections on the amp. If the voltage is good and the protect light is still coming on, your amp is broken. With it's intermittent nature, you may have broken legs on the output transistors of the amp. This is a common problem with those amps if they are mounted to a sub enclosure.

hifonics amps are notories for doing that there doller to watt ratio is unbeatable but with reliabilty you cant count on them..kinetic batteries help the life of these amps...

How is simply adding a "kinetic" battry going to make the life of that amp longer? Keeping you voltage up to keep it within it operating limits yes. But simply just adding a batt to a sub par electrical system is just asking for yet one more problem. -------------

That is really a no brainer. The HiFonics rep also reps Kinetic batteries.

well like the other guy said its a no brainer!!i im a very experianced hifonics user and i kno that hifonics amps can draw lots of power and if the amp isnt fed the power its drawing from your electrical system it can damage your amplifier..thus shorting its lifespand...and yes by simply adding a kinetic battery to your system it will maintain a constant voltage power supply to the amplifier witch will help the amp perform properly and keep it from being damaged due to low voltage supply to the amp..this can be applied to any amp but hifonics ecpecially..
