VS Berlina/ KJ Verada/ 88 Trans Am
Help me before I burn my car! This prob has been ongoing for ages, and its in my verada not my berlina so I hope y'all don't mind giving me more advice.

When everything was factory, I had no problems. Once I started screwing around it all went south. My front speakers cut in and out with no consistency and its driving me nuts. I have factory front splits, which are amped, 2 alpine type s subs amped. Both amps run off the same power cable and currently sharing an earth ( I have been meaning to run separate earths but haven't had time) running through 2 distribution blocks. When the fronts cut in/ out it takes my subs down too. When I disconnect the front wires from the amp the subs don't ever cut out, but when I connect the speakers back up, bam some old ****. In my quest to fix this I have: bought two new amps, changed power and earth to 4 gauge, redone all connections and redone terminal ends, new battery, 100amp anl fuse, ran new front speaker wire, switched between 3 head units.

Unless some one can offer some other ideas im left with buying new aftermarket front splits and running new wire for them too ditching all the factory wiring, running separate earths for the amps, blowtorching the whole car.

Tired of spending money eliminating things!! This is a stupid problem which ive never encountered before.
HELP!!

Well why don't you start with running a seperate power cable to each amp, or atleast a larger cable ino a distro block that has 2 cables suitable for the current draw on the amps.

Why would you disconnet the speakers and say the subs work fine when the speakers are the issue, surely you'd disconnect the subs instead, then investagate the problem. I'd reccomend you start by doing that.

I'd also bet the mono draws more current so it takes priority over the multichannel, make sure you battery and alternator are up to the task awell.

Finally how do you run a 4 awg cable in to 2 distro blocks, i'm confused. More info needed here, you can't run 4 awg then split it into 2 x 4 awg (you can) but it doesn't work that way, how do you have it set? You need to be really specific otherwise were guessing at best.

Have you measured voltage at each amp to see if one of them are dropping?

Also when is it cutting in and out? At a reasonable volume level? When it's been running at higher volumes? When you go over bumps? Erratically? Can you do something that will cause the speakers to cut out? When the amps cuts out, does it go into protect mode or does it shut off completely?
