[QUOTE="highhpsupra, post: 2211102, member: 569075"] I installed my US Amps IS2200 today and ran into a problem. I am using 8awg wire temporarily and used only one channel on the amp at 4ohms. The amps rated output at 4ohms on one channel is 200RMS, so 8awg should be good enough. The fuse on the amp are 3x30 so 90 in total. However, the fuse at the battery is 50amps. (AGU fuseholder) Everytime i start the ignition the fuse blows instantly. Even with the amp on the lowest gain setting. Any idea on what can be causing this? When i did a search it said a short in the power wire can cause this, so im not going to rule that out. I also read that you can test for a short in the wire by disconnecting the powerwire from the amp and taping the end off and putting a new fuse in to see if it blows. If it blows then its a short in the power wire, if not its a faulty amp. Correct?? Any other things that i should look at before diagnosing this amp as a desfective one? Thanks for the help. [/QUOTE]
