subs stop playing

[bladebarrier 10+ year member]

ok well i went out today and started bumpin again. and it shut off. i get to mcdonalds and my friends wanna hear my system. so im bumpin for like 6 songs straight. nothing has turned off. but then i start driving and sure enough it turns off again after like a minute. it was dark and my amp has blue leds on it so i can see under my seat when its on and off. and when the music turned of the lights of the amp were flickering. so thats good news to me. its the amp and not the subs. so does anyone have any suggestions on what this could be. it has to be wiring of some sort. this is the only thing i can think of. my second battery (kinetic hc 2400) has 3 1/0 wires coming off of the - terminal. but the threads are stripped in the battery so i cant get them off.so i ran one of the wires to a distro block and had 2 4 awg wires runng out of it. one went to the amp and one went to the chasis. this is the only thing i can think of.
thanks,

4 gauge is plenty for a short run, so I doubt that's the issue. Is there anyone that would let you swap a similar amp into your system for an hour to double check? Your amp could be failing, but it would be best to make sure it's not a wiring issue, by trying out a different amp first.

How's the ground on your amp? Have you used your meter to make sure that the resistance on the ground line is as low as you can get it? Is it straight to the frame, or is it grounded inside the trunk somewhere that might not be as good as it looks?

The fact that you replaced your alternator connections yourself, makes me think you know your stuff, so I apologize if that question offends you, but now that your amp is able to draw more power, it could also build up heat faster if it isn't getting a really good ground.

i doubt any of my friends would let me do that just because its "professionally installed" and they dont want me to mess it up because im not a "professional". but i will be getting my new sundown saz in about a week or so. i bought it from some guy on here and hes waiting for my e check to clear. but anyways i havent gotten a meeter yet. i will go get one today. and the ground on my amp is fine im almost positive of that. the paint is off and its bolted down to the chasis. but what would i check for in terms of resistance when i check my grounds? and no it doesnt offend me at all. id like to think i know my stuff but its times like these that make me think otherwise..//content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

This is a pretty good read about grounds. Some of it is written a little more technical than it needs to be, so if you have any questions on how to do it, shoot me a PM and I'll walk you through it.

I'm surprised there isn't a better sticky here somewhere on grounds, but the only one I saw was about as helpful and experienced as the average "pro" at your nearest Best Buy or Circuit City.

ok well it turns out its a bad ground after all. i finally figured it out. i have a kinetic hc2400 and i have a distro block for the two ground runs of 4 awg. one to the chassis and one to the amp from the battery - and one of my wires keeps being difficult and is loose in the distro block even if i tighten it. its weird.but anyways im almost positive thats it. how do i check a bad ground with a dmm again?
