How do I reset the amp... the red light is flashing on the amp...the car was bought used and i have no information on the amp.. the amp has power.. it has good ground. the amp trigger wire is also working with the key on and the fuses are good.. but i cant seem to get any sound outta the speakers... thanks
The amp will reset every time it's turned off. The red light flashing, instead of staying constant is a warning that one of the protection circuits are activated. If the amp is bridged wrong, it can do this. If the load impedance is too low, it can also do this... don't trust the speaker, it it says 4-ohm, it may actually be 3.8-ohm, which could cause a problem if two speakers are wired in parallel. If it's not getting enough power, it will turn off briefly, but will turn back on after a second. A capacitor is not necessary with this, just use 4 gauge cable and have a good battery... make sure the ground is good, that one is commonly ignored.
Hi, note that if you are not using the proper gauge b+ and gnd cable with this amp then the current available at the amp wont be sufficint to keep amp on. also try using this amp while vehicle is idling. if this doesnt work then disconnect all spks from amp and check if red lite stops flashing. if it doesnt stop flashing then amp has internal fault. if lite stays on brite then proceed to check each spk load impedance, then reconnect each spk individually. the minute red lite starts flashing it will give you a clue that the channel or spk load is faulty. cheers

that means you probably have a shorted speaker wire, a bad speaker or the amp itself is bad, try disconnecting the speakers one at a time and see if it turns on or not. if the red light stays on with no speakers hooked up it means the amp is bad
Unplug the stereo input signal from the amp. If the amp does not do it
with the wires unplugged, you may have a problem with the radio sending
too much voltage to the input of your amp causing it to go into protect
mode. If it continues it is in your power source to the units. Let me
know and I'll see what Ii can do. Hope this helps...
Actually, it's more likely that the problem is on the outside of the amplifier than the inside. Your problem may be caused by a ground wire that's come loose from the grounding point, a defective fuse or corroded connection on the power wire, an overload of the remote input wire, or a problem with the head unit that your amp is connected to.
The easiest way to troubleshoot is with a voltmeter. Test the voltage at the amplifier's main power terminal and remote terminal while the meter's black probe is connected to the ground terminal. If you find voltage dropping on one of the terminals, you can focus your attention on that wire.
