My freind and are installing a box with 2 12's and a 760 wat amp. The amp has 2 25 fuses and they keep poping what are some possible problems/solutions

make sure your not grounding the amp out, also does the amp have thermal protection or anything like that. ya might be puttin a load on the amp that it cant handle, check the way your subs are wired, might be 1 ohm, and the amp is 1ohm stable.what type of amp is it? 2ch/4ch or mono?

well, when he says 760 watts, that makes me a little leary, mostly due to the fact that the only amp that says "760 watts" is a sony amp. and we all know about sony car audio equipment.

actually, pioneer makes a 760 watt amp.
What kind of equiptment are you running and how do you have it hooked up

Sounds like a mismatch of components, gain control settings and wiring of subs. Give us some details on your gear and how it is wired.
1. Sub brand and type (Ie: RF DVC, 4+4 ohm or SVC 4 ohm)
2. Amp brand and type (Ie: Power Pooper, 2 channel, bridged MONO)
3. Subs are all wired parallel, or combined series/parallel
Thanks,

the easiest way to trouble shoot is with a multi meter... You need to start by verifying EVERYTHING is measuring out the way it should.
Start with the speakers. - Disconnect the speakers at the amp and measure the impedence (ohms)that the amp sees. You have to disconnect them from the the amp to properly measure them. Should be within an half an ohm or so of what you were planning on wiring them at. If it is anything different then you need to pull the speakers and see if the wiring is correct.
Next is voltages.- Touch the ground probe to the ground poinnt on the amp and measure the constant and remote wires. Remote wire should have nothing to do with it but check EVERYTHING.

Ttocks has the right plan... check the key components you have with a multimeter.
1. Measure the ohms resistance of your subs as wired, but disconnected from the amp
2. While the subs are disconnected, power up the amp and see if the amp pops fuses again? If no, amp is probably OK, but sub wiring is either incorrect to amp or there is a shorted wire or voice coil on the subs. Have to review that in more detail.
3. If the fuses blow w/o the subs connected to amp... there is a problem with the amp and needs service
Good luck and let us know what you find out OK?

what ever happened here?

He is still checking? Betting it was/is an amp problem and the amp is in the shop???
My guess...
