ahhh whats going on? this is sooo annoying. got 2 12 mtx6000 hooked to jl 500/1 in a dual ported box... when i crank the stuff it makes car headlights blink big time. its brand new car.. (well 2001) new battery. Rite now its on 8guage wire, and hooked to stock GM deck with low level converter... help!

beef up the battery to chassis ground,alot of ppl forget to do this.there is a few other possibilities,but start with that.L8r.Rob :cool:

dont get you... right now the battery is grounded to the the body... well it came like that stock from chevy.....

yes just make the ground wire bigger, at least 4gauge [img]smile.gif[/img]

Most cars only come with a wimpy ground wire about 8 guage. This ground wire is fine to handle all of the car's electronic accessories, but when you start adding more stuff, it won't handle it as easily.

You may have the biggest wire from the battery positive to the amp. Equally huge wire from amp to chassis, but if you leave the factory stuff from the chassis to the battery it would be like your entire system was wired with that small stuff.

If you think of electricity in terms of high ways and traffic, you know what happens when you suddenly go from 8 lanes down to 4 - MAJOR conjestion. Keep the lanes wide the whole way through your system. The car's electrical system is a loop, and the final stage of the loop is from the chassis to the battery

sounds goood, iam goto local shop pick up 2 feet of 4guage ground [img]smile.gif[/img]

So the ground i attach it directly to the battery right? and then to the chassis... how will they hold, sodier it?

thanks

use ring terminals.

I usually connect it to the original ground with a ring terminal (although finding 4 gauge ring terminals isn't easy around here ... Most audio shops around here don't even understand why you should upgrade the big 3)

If you are not picky about looks, you can use a welding lug ring instead of a fancy ring terminal. They can handle up to about 2 gauge wire. I crimped then soldered mine onto the wire and it seems to be working well.

IF this doesnt solve the problem what else could it be? I need bigger altnator? Will upgrading to 4 guage wire also help?
