How do i diagnose problem?

you need to answer this question: how are you wired? in detail. for instance, i have 0 gauge with 300 anl fuse at battery.. which goes to distro blocc.. two 4 gauges go from my distro to my amps. the sub amp has no fuse between itself and the distro block. a 60-amp fuse is between the distro block and components amp. now when the fuse under my hood blew, i knew it had to be a short somewhere between the battery and the distro block. how did i know? becuz the component amps's fuse did not blow. i discovered the distro block was being pressed against the chassis (ground) under the back seat. i solved my problem. now u need to describe how your system is wired and where fuses are...

well, ive already stated this. i am running 2 awg wire with a 100-120amp ANL fuse by the bat. no distro block. amp appently has no internal or external fusing. i also have a 300/4 wired with 4 awg. and since the 300/4's inline fuse didnt blow, it must be a problem between the 1000/1 and 100amp ANL, right?

there, i think i just summed up the whole thread 4 ya.

you might have to "un-install" stuff depending on wher it could short out. checc all the most possible places first.. for instance, if you have a distro block that is exposed with insulation on it.. or if you ghetto-rigged two seperate lengths of 2 gauge wire and twisted together or some ghetto shit like that.. checc the wires at places u think the wire might be being squished or something.. or possibly the insulation of the wire got penetrated somewhere.. u have to find the short. there is no tool that helps u find shorts i dont think.. unless u have extensive knowledge and know how to use a voltmeter to checc for continuity.

the only place it coulda shorted is where it enters my firewall, but i already checked that and its ok. oh and it coulda also shorted in the engine bay, but i checked that 2. and since a local shop said that older 1000/1's have a problem with the power and ground shorting inside the amp, im thinkin it might be that. but i dont know how to check...

if u wanna eliminate that as a possibilty the best way is to try a different amp temporarily and if it runs fine you know its the 1000/1. do u have a voltmeter that makes a beeping sound when theres continuity? if so, place a voltmeter lead somewhere on the 2 gauge positive wire and put the other lead on ground.. if it beeps, you have a short somewhere.

actually, if you have a voltmeter that beeps when theres continuity, you can hook the leads up to the positive and negative terminals of the 1000/1. if it beeps, then its definitely shorted inside the amp.

have you opened the amp to see if anything looks bad?

i dont think my DMM beeps. can i check it at the amp without a beeping DMM? and no, i havent gotten around to opening the amp yet.
