heres the funny part.....i did, im one of those flat broke do it your-selfers

And your going to be even more broke now because of this. If you don't know what your doing, search around in your area for some help, or just save a few more dollars and have a shop do it. You doing it yourself more than likely caused this problem, and you will have to pay for it now....

with all due respect its not that i dont know what im doing its that this is my first time doing this. considering my amp is close to 20 years old i would blame that more than i would blame myself....

sorry double post....

can you take a picture of how the speaker wires go into the amp? that will help us determine whats going on, if anything, with the wiring end of things...

i dont have a camera, but i can tell you i have only the sub wired to the amp. i have the pos from the sub going to the white wire off the amp (front right pos i believe it is) and then the neg off the sub is going to the orange off the amp (rear left neg i believe) ive been told to use the white and gray wires off the amp but that gives me the exact same results, however i will switch from orange to gray just to be safe. and then of course the red remote is going to the antenna power blue off my head unit. (and obviosly power and ground, i have my main ground going into the engine bay to a bolt on my frame, maybe i should shorten the ground cable to under 2 feet??)

i wonder, could this be because i have my RCS'a going from rear output off my head unit into the front input on the amp? this problem didnt happen until i did that, before that i had it going from rear into rear but switched it to bridge (apparently my amp wont bridge unless it has front input)

EDIT: not the rca's....i just switched from rear output to front output and same issue. interesting tho when i switch from 4 channel bridge to 2 channel bridge the sub's cone doesnt extend outward as much when i power the system, it does still do it but only maybe a 1/4 inch instead of all the way. i would assume thats because it only getting half the power it was on 4 channel.

ok so this thread appears to have promising hope. i do have engine whine and on/off thumps, i did kinda a wierd ground on this system so im gunna relocate all grounds and do my best for ground defense if you will lol ill update after if this solves it.

idk what ohm its wired at (how do you tell) i all four channels of my amp wired to the one sub ( front right pos to pos on sub and rear left neg to neg of sub)

did everyone miss this.

and i like the noobs (most seeming not so knowledgeable) helping noobs (again, most seeming not so knowledgeable)

yeah i was considering that to be an issue, but ive read that wasnt even possible so i dont see where the issue could lie if its not even suppost to be capable of doing it. i have used one channel i have bridged only 2 channels and same exact thing just on different levels on 4 channel it extends all the way on 2 channel its a lot less and one one channel the cone stays seating properly but the on off thump last for about 2 or 3 seconds and its more of a squelch then a thump.

if i may ask......if you have identified the problem, might you have some contributing advice rather than noob this noob that????

you should have ch 1 & 2 bridged going to one coil, and then ch 3 & 4 bridged going to the other coil, that should be the only way I see this working.

when you say coil i assume your talking about the voice coils? there for i also assume your talk about ch. 1&2 being bridged to the 1st voice coil and ch. 3&4 being bridged to the second voice coil. im going to assume again that your talking about a dual voice coil sub?

i only have a single voice coil sub and i have all four channels bridged to the only terminal on my sub.

im starting to think this whole thing is just a ground issue so im gunna relocate the grounds for my amp and for the head unit and see where that gets me.

if you have a single voice coil sub you can only have either a single channel going to it "A" or you could have "A & B" Bridged to it, giving the sub more power... your application seems to be the problem here, not the amp, nor ground. one sub, one coil, one speaker wire going to either one channel or a pr of bridged channels.

if I read you right, you are the flaw.

LOL! Then undo 2 of the channels. That is not how this stuff works. This has nothing to do with the age of the amplifier and everything to do with you having no idea what you're doing. Everyone is trying to help you so listen. Quit dicking with your grounds for right now and unhook 2 of the channels from the sub. You cannot bridge 4 channels together!!! If you really did that, you most likely would have fried your amplifier, but somehow maybe you've gotten lucky and it has survived. Since that seems to be the case, only bridge the fronts to the sub or the rear.... whichever you connected your rcas to.

Next, checking your grounds and making it better will get rid of engine whine and turn on pop.
