you have a short....check your wiring




My car may run 18s, but I can do your taxes in 10 seconds flat.

Yeah, it could be pinched somewhere and even just a little metal touching the insides of the power wire will blow fuses. Mine did it once because my slider cut into it a little bit, fixed it and re-ran the wires under the center console.

somewhere, your power wire is touching metal.

check the battery connections. And check your amp connections. Usually power and ground wires are right next to each other, a stray strand touching the ground can cause a short.

actually my one amp did that and it ended up being something internal was blown, get it checked out, does it blow even with the power of the car turned off? like no key in the ignition and you go to put a fuse into it and poof it blows?

If the 12V wire was touching ground, it would still do that. Not necessarily something internal. But don't rule it out. I would hate to see someone send an amp back thinking that was the problem and the new one does the same thing.

Check your grounds.

Disconnect your power lead to your amp and make sure it isnt touching anything(tape it off if you have to). Now try replacing your fuse. If it blows then you definitely have a short. If it doesnt blow then reconnect your power to your amp. Now, if it blows it is definitely inside your amp, or you have a really bad ground.

all I did that was much easier was run jumper wires straight from the battery (with the amp on a bench near the car) to the amp and tried it there but it still did it, much easier than screwing around with grounds and power wire under your carpet, besides if it was a power wire touching somewhere it would be popping the fuse under the hood not at the amp

when did it become known which fuse was blowing?...not trying to be an arse but it really helps to know
