i have sony 760watt xplod amp the fuse on the amp its self blows out all the time what can be casuing this to happen????

 

Q1: What is the fuse rating on the amp's fuse that keeps blowing? Is there only one fuse protecting the amp?
Q2: Does your main power wire have a fuse that will protect the wire from catching fire?
Q3: Do you have a fuse protecting the amp from excessive power surges?

I'm going to assume that this amp is the only amp that you are using, and I'm also going to assume that you have probably wired the amp incorrectly. I personally installed and wired two amps in my car, and I haven't had any problems thus far (knock on wood). I also did my homework and asked a GANG of questions.

I'm guessing at where you may have made a mistake in your wiring, so please correct me if I'm wrong. I'm assuming first that you installed the amp yourself. If so, you may have wired the amp directly from the battery without using a fuse to (1)protect the main power wire, (2)protect your car from catching fire, and (3)protect the amp from excessive power surges. I'm not that familiar with Sony X-plod amps, but I imagine that you're going to have to take a fuse that is rated at enough amps to protect the main power wire from catching fire. I'm guessing that your amp's fuse is 75-80A and you're going to need a similar amp fuse to protect the main wire. If you happen to have more than one amp powered by a main wire, you'll have to add up the amperage draw from BOTH amps in order to get a fuse that will protect the wire with enough amperage to flow to both amps. (EX: 50A + 60A = 110A > In my case, I have two amps that draw 50A and 60A respectively, so the fuse for the main power wire has to be at least a 110A fuse in order to protect the wire from a larger surge of power drawn by both of the amps (or something like that). IF YOU DON'T HAVE A FUSE PROTECTING YOUR MAIN POWER WIRE, YOU RUN THE RISK OF YOUR CAR CATCHING FIRE!!! The fuse is supposed to be there for a reason, so use it.

Good luck!

There's some problem in the wiring. Make sure the wiring you use for your power and ground are sufficient to the specs of your amp. I'm not familiar with Sony's amps at all, so I don't know the specs of the 760, but if its a single amp not pushing too much power (less than 500W rms), you could probably get away with an 8ga power and ground wire. Any more than that, go lower. 4 is always a good, safe bet. Make sure that your ground wire is the same size as your power wire. Check the ground and verify that it's firmly grounded to the chassis at a point where there's metal.

Also, make sure that the speaker(s) you are using are connected to the amp properly. If you're bridging a sub, make sure the amp can handle the load stable, impedance-wise.

Do you have an inline fuse near the car battery (if not, as indicated in the response above, you should, and it should match the specs of your system power-wise)? If so, is it blown?

 

ok i have a fuse on the power wire and on the amp they both now have 30amp fuse when i turn up the gain on the amp the fuse on the power wire 30amp bloes out? what can cause the problem?

 

Well a 30amp fuse isn't enough for 760 watts (assuming it can really deliver 760 watts). Make sure the fuse that is in the amp is the right size (ie: what originally came in it).

You should have a 60 amp fuse in the main power line if you're running an amp with 760 watts. I'd also guess that the fuse in the amp should be bigger than 30A. Check the manual.
