yeah i have a 800w 12" pioneer sub, bridged to a 760w pioneer amp and it acting funky. its fine at low volume setting but when i turn it up to about half way it like pops and cuts out a little then a little bit higher setting and it jsut doesnt play. any help here. i already am runnoing a ground al the way back to the battery 4 guage so i think thats good i think the positive wire might have a @!#$ty terminal on it at the battery could that cause this. any thoughts/help appreciated. thanks

it's not ghetto, it's "in progress"
first of all...your ground should be as short as possible.

I dunno wuts going on, but one thing I can say is u want the shortest ground possilbe.
if it ain't broke...MAKE IT GO FASTER
I dont think its the ground....there has been much debate about grounding to the battery, but I have done it this way for a couple of years and have never had a problem....it fixed some of the problems I was having with the short ground.

How are your gains set? Is your amp clipping and going into safety protection?
Maybe something broke internally? I've heard of friends of mine having issues with the power input part of the board breaking off, specifically recent Pioneer amps.
I had the same issue a couple of years ago with one of mine.

um,i hear that gm doesnt use any solder just clips so grounding to the body is pretty weak. and at AMS, a local sound shop, they highly suggest running a ground right back to the battery with the same guage wire as the power. thats why i did that.
the gain is on the side of the amp. its a little flathead screw type lookin deal. i have it set at about 3/4ths of the way up.
i muted my other speakers, then turned t up til 10 volume thats 1/4th then i adjusted the gain til the sub sounded good.
the power terminal on the amp looks good. i got a rf wiring kit and the rca on the clear wire, when i plugged it in then unplugged it from the amp the rca jack like popped out with it but i thinks thats ok. if it is the amp i got the insurance on it so i could just go get a new one for free.if you think thats my best bet.

Are you saying the RCA jack came out of the amp itself? As in BROKE? Cause if that's the case, that's probably what a lot of the problem was. But in theory, the entire chassis of the car is a very good ground ( as it's grounded to the battery anyway), hence the "shortest length" of the ground wire. That way, you're not adding extra wire resistence to your ground wire by running it 18 feet. The only reason I could see for them suggesting to run it all the way back, would be if there was a crappy ground between the battery and chassis up front (though I assume you would have other problems beside a crappy amp ground).
If you have a bad power connection, I guess it COULD be adding resistance to the system, and then it's tripping the overheating circuit in the amp....not very likely though. Possibly clipping protection. Try turning the gain on the sub amp all the way down, turn the deck (and other speakers) up until about 2/3 volume (or until you hear the distortion), and then back it back a hair. Then leave it there and turn your sub gain back up slowly. See if it keeps doing it with that. Other than that, I dunno.
if you have a bad ground yoru ground connection at the amp should be hot.
as far as gm not using solder and using clips not sure what your meaning by that. ive seen the robots welding the pieces of the body together, and from most tests ive done the diffrence between running a ground straight back versus a short 2' ground is negligable. so i save myself the expensive wire cost. did you buy the gound cable at the shop and have them install it?
"i muted my other speakers, then turned t up til 10 volume thats 1/4th then i adjusted the gain til the sub sounded good."''
what did you turn to 10? your headunit? if it was the headunit, how high will the volume go before it stops?

i mean all the wiring gm does is clips, no solder. and no i bought the wire at a farm and fleet and installed it myself. yes i turned my headunit up til 10 volume its max is 40 so ten is 1/4th of the way up.

does the amp shut off ...or just the speaker stops playing?
visually check the connections INSIDE the box as well.

naturally, if you set your sub gains to be good at volume 10, then turn it past that, you're gonna have distortion, and other issues. You would want to set it up at the volume where you would be at your loudest. So if you never turn past say, 30, tune it at 30, not 10.
right, charles.
slowgreenfire, if you set the gains with your headunit set on 10. your not going to be able to turn the headunit up past 10 without getting into problems. turn the gain down all the way. then turn your head units volume up to maxium before any distortion sets in, then adjust your gain up. u should be able to crank that headunit up to the 32-35 range before distortion sets in.
as for not using solder on their wires. wether they solder an electrical wire wont have any effect on your ground, your ground is ran to the body of the car and runs thru the cars body. not the cars electrical wiring. and you should upgrade your groun from the battery to the body of the car on any install you do.

alright ill set my sub up like that. and yeah i just heard the cars stock ground was really crappy
