Hey guys. This is long but I need some help... I'm having some touble with my stereo system. I have two 10" woofers hooked up to a Sony Amplifier. This set up is pretty new. I've been running the stuff for maybe a 1.5 months without any problems (sounded awsome). All of a sudden, I burnt a fuse today (the one near the battery). I didn't think much of it and replaced the fuse. However when I turned the tunes on there still was no bass!! I just heard a slight pop in the beginnig. I checked the fuse in the amp and it was fine. I checked the fuse near the battery (the one I had just replaced) and it was burnt again!! The same thing happend again and again. I burned 4 fuses in a row this way (as soon as I turned the stereo on). Can anyone tell me what's wrong? I know for a fact that my subs are fine (I checked them in my neighbors car). The ground connection for my amp is solidly connected. Remote line is fine. The other connections seem to be fine and not touching eachother as well. I'm starting to think my amp is screwed. It's only a 1.5 months old though... Can some of the car audio experts please help me? Thanks guys.

No problem, I'm willing to bet you have a grounding problem on your main power line (positive) somewhere between the fuse at the battery (that you keep blowing) and where it connects to the amplifier. Chances are that the power cable's insulation has either cracked or been warn away in some place allowing the wire inside to come in contact with the metal frame (ground) of you car. Therefore creating a short circuit, and cooking your fuse. If you happen to have a continuity tester handy, you can test for this by checking if you have any continuity between the wire there it leaves the battery fuse, and ground. Often when people install car audio components, they forget to use some form of extra insulation between the main power wire's insulation and the car's body (ground). This often occurs when the wire is fed through to the trunk where it can easily come in contact with the body and eventually the insulation will be warn away by the constant vibration of the car while driving. Hope this can help, Dan

Thanks Dan and "pescioo7". If the main power is grounded somewhere would that cause the fuse near the battery to burn exactly when I turn on the stereo? Also can you explain this "continuity test" for me? Thanks again guys.
