Have you replaced the factory battery? Have you done the big 3 upgrade? If not doing these would be highly beneficial.

pull the main fuse to the amp and see if the car still has issues with stalling at idle.

Put the electrical system on a voltmeter to see what it's showing when these problems happen.

amp may have an internal short drawing excessive current.

electrical system is NOT the problem........

If the amp keeps blowing its fuse the problem is THE AMP.

You mean you put in a HO alt without doing big 3???? Not only is that just plain dumb its extremely dangerous... stock wires do not handle that kind of current.



And lets see, crap EA alt, crap optima battery, capacitor..... not much we can do with that pile of fail.

Frito, you're still missing what we've been saying.
The amplifier seems to be the problem. Take it into a shop and have it checked out on a bench to see if it's drawing more current than it should due to an internal short circuit.

Odyssey has good batteries in the deep cycle catagory but you'll want to isolate it with a battery isolator rated for equal to or greater than the current output of your alternator, if the battery is for the audio system as a second unit.
any RV shop or on-line should have the isolators for relatively cheap.
