    sweet. good news. the amp powers on with out any subwoofer connection. the polarities are checked and good.
    i am worried that there is a short somewhere. and i dont know what that looks like or where to find it.
    the other thing is one sub is an almani dual sum.n and the other is a pioneer. prolly too much juice for one sub. the thing is they were woring fine together before.
    what is the next recomended step?

SOURCE: smoke and no more juice

I Have also had this happen to me, pretty similar around the time it happened to you also, but I'm not just getting my hands dirty and inside the amp. If I fix this, I'll be sure to let you know what it was that I did, or bought and replaced......... I would also like some ideas and support on this if this has already been taken care of

SOURCE: amp blowing fuses

The amplifier probably has shorted output transistors.

Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).

Which fuse in the fuse box belongs to headlights in 2002 Ford Escape?

The fuse box is beside the battery under the hood. The fuses and what they relate to is marked under the lid of that fuse box. Use same size fuse if it needs replacing. If in doubt check all the 15 to 30 amp fuses.

It could be one of the three large fuses under the dash, or it could be in the power distribution center under the hood. But it does sound as if a main fuse that feeds the smaller circuits has blown.

Got new head gasket installed-not related to prob.after that bat.went dead,new bat and alt. still drains bat overnight. could it be a short in starter?

Check the main alternator fuse. It is either a block fuse in the fuse box under the hood or it is built into the positive battery terminal. If it is blown your battery will not charge even though everything else is in perfect working order and the alternator light(charge light) on the dash will not light up to tell you there is a problem. You will drive a short distance and the battery will go dead. After recharging it will start right up run OK till it runs out of juice again and dies, etc. Find the fuse and check it is not blown. It is a frustratingly simple fix to a hard to diagnose problem.

Something is shorted, large amp fuses do not just blow. Go under the hood to the big black box marked FUSES. You are looking for the blown main ALT or BAT fuse, but you must find out why it has blown.
Make sure nothing has shorted out your positive battery cable, accessary wire, did you add anything to the electrical system that was not fused ?

Blowing of fuses

The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.
