Question about Alpine MRV-F540 Car Audio Amplifier
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.
