MA audio blowing fuse

Hi, ive had the ma audio hk-800d for quite some time, recently i upgraded to a alpine cd-player. THe model for that is cda-9813. Today, i ran the power wire straight form battery, i ran 10 gauge as per alpine instructions. Well, after a installed that the amp never really ran right since. Today, on the way to work it was makeing funny scratching noise like the sub was blown, so i cut all amp signal. Even with amp turned off it was making scrathing noise. eventually it stopped. So i got to work and turned signal back to amp, and nothing. I looked and the 30amp fuse was blown. So i watied until after work and replaced it and it blew immediatley. What would cause this, i re-checked power and ground wire and they're fine.

if the fuse on the amp blew, immediatley sounds like there is a direct short some where in the amp.

in the amp. nothing esle has changed recently. the sub is not bown though, i suppose the wires in the box that hook up to the voice coil may be touching, but that would make the protect go off would it not. I don't thnik it's the amp, it's never been stressed and it's only running a 4 ohm load.

If its blowing fuses, the power supply in the amp has a FET open and is direct shorting to ground. It needs help //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
