I hooked up 2 10" subwoofers (250 rms each) and 2 4"x10" rear speakers (150 rms each) to a 4 channel amp (75 rms per channel). It was working fine for about a week, then the rear right speaker smoked, stank, then the amp went into shut down mode. The 2 subs and the rear left all work until the amp shuts down. I have a 1.5 farad capacitor leading into the amp, and my ground is secured tightly to the frame of the car with about 8 inches of 4 g wire between the amp and the bolt holding it down. I have checked and dble checked to make sure there is no pinching of any wires, and I can't figure out what is going on. Please help if you can. Everything is rated at 4 ohms, nothing is in bridged or parallel mode. It is straight wired: 4 channels, 4 speakers.

No matter what the specs say...there is no way a 4X10 speaker will handle 75 watts rms....more like 30. That being said your right rear 4X10 is history...when the smoke gets out it's gone! If your running any bass to them at all, it will continue to happen when you replace it/them. You need to cut out the bass to them....anything below 120hz approx. Your amp should have some sort of crossover built in. It all depends on brand on how to hook up. That will help some. Also watch the gains on these channels. Don't run them all the way up...cut back some and the 4X10's will live a long natural life.
Your amp should be O.K. if it's of quality. Just replace the 4X10 and you should be ready to go again after your readjustment of the amp. If you're not sure, got to a quality shop. They shouldn't charge much to re-wire the set up for a longer life and help with the adjustment of your amp.

You have melted the voice coil in one of the speakers, and it's shorted. This has either damaged the amplifier or put the amp into "protect" mode. Disconnect the damaged speaker and see if the amp will play the others. If you have a component that smokes, never leave it connected to your other components.
