Amp keeps turning off

I have a hifonics brutis amp and 2 kicker cvrs. recently the amp keeps cutting out. there are lights that are on thr amp that stay on but the little power light turns off. the protection light has never came on. this started happening when i tried playing it when it was really cold out. but after it warmed up it continued.the amp sometimes doesnt work at all and sometimes it works at very low volume. it is a brand new amp (about 3 weeks old) so my guess is its defective

An amplifier needs minimum voltage (usually 6Amps) to turn on. If there is 12V at the input of your amplifier, check the remote for 12V as well as making sure the ground is secured. I suspect based on limited information, that your alternator/charging system is the culprit.Take your amplifier to a local shop and have it bench tested (abuot $10) they will hook up to an independant power supply and verify its properly working. Then it can be eliminated as the source of the problem. Also be sure your wiring and fuse are accurate for the amount of current draw.
Since your protection has never come on, and the power light is going out altogether, you may have an input voltage problem.

MAKE SURE YOUR GROUND WIRE IS GROUNDED GOOD,,AND IT IS IMPORTENT TO HAVE YOUR REMOTE WIRE HOOKED UP. IT WILL BE A BLUE WIRE,,FIND THE HOT WIRE FOR YOUR TAIL LIGHTS AND HOOK IT THERE THEN WHEN YOU TURN YOUR CAR ON THE AMP WILL ALSO COME ON.THAT SHOULD STOP ALL THE NOISE AND POWER YOU UP.

Can i bridge this hifonics amp


If you don't know if the amp is bridgeable, then I wouldnt do it. It could already be bridged internally and bridgeing it through the speaker terminals could be disatrous, i.e. the infamous blue smoke of death. The amp looks like a 2 channel amp fromt he pic and you have two speakers you are trying to power with it. So the safest bet would be to just unbridge your speakers and hook them each up to the amp as normal. No blue smoke. Good luck!

Speakers cut off when bass goes up


probably the amp going to safe or protect mode judging by the fact that you have 3 subs wired to it i would say it is not 1 ohm stable try disconnecting 1 sub and see if it still happens this will be running a 2 ohm load rather than 1 if it stops happening then you need to figure out a better wiring configuration that will work with your amp.

My amp turns on then off while it slowly blows the fuse out


If I were a guessing man, I'd guess that you had your amp hooked up in a bridged configuration. And also that you connected your two speakers in parallel (plus to plus and minus to minus). And if I were to further guess, I'd guess that you have a blown amp now because of what I mentioned above. Sounds like you need to spend some quality time with your favorite electronic repair shop. Good luck.
