very werid electrical problem with new pos amp

[brickloaf 0]

i had a t20001bd on my btl for a loooong time but finally sold the amp and the whole charging system but still have the sub im trying to sell, but i bought this kenwood 9102d from a buddy so i could thump while im trying to sell my sub...

when i have all the wires connected (and yes it is hooked up perfect this isnt my first time) the power light does NOT come on, but the remote wire has enough voltage and the power wire is good (checked with volt meter)....BUT when i pull out BOTH 30a fuses the red power light comes on for like 3-5 seconds then fades away, but voltage and everything stays the same on the amp...the 4 channel amp i have hooked up next to it off the same battery works perfectly fine...

what im thinking is the amp might just be fucked but the fact that the power light comes on when i remove the fuses makes me wonder...maybe a bad ground? but its grounded in the same place my 4 channel was grounded so it should be good....

any ideas anyone??

yes check your ground to make sure it's efficient

well i took off the ground and reconnected it and it sparked up so i know theres power going through it but it still does the same thing

yea i had the same problem with my old amp. i regrounded it and it did the same thing.i got a new amp and it works fine...i think the amp you have is gone.

You should never unhook the ground with the power wire still attached, let alone then hook the ground back up to the amp. If it wasn't smoked before, it most likely is now.

nah idk about that with my old setup i disconnected the ground first many times and never had a problem with the t2k

If you have power going to the amp but no ground attached, that power is looking for a ground anywhere in or around the amp. If a stray wire or tool touches the amp in the wrong spot, you'll see some fireworks. If the fuse is pulled from the power wire obviously there's no problem with this. But having a live power wire plugged in is asking for trouble. But hey, if you've done it a bunch of times and never had a problem, maybe you'll keep getting lucky.

check your remote wires

Very unwise, i've smoked an amp this way. my ground rocked undone and my amp arced on my chassis.

Um... if removing the ground wire first from an installation is the wrong thing to do...

Then what's the difference in removing the ground from the chassis vs removing the ground off the starting battery?

Once the ground on the starting battery is removed, ALL grounds from all equipment in the car has been removed....

So, should we remove the fuse box out of the car before unhooking the battery?

That doesn't make sense...

I think some of you or i have misinterpreted what he meant by removing the ground....

[jcarter1885 995]

Yeah i have removed the ground wire before and it wasnt a problem and hasnt been for years that I know of, never damaged an amp or anything else by removing the ground first and then putting it back.

Shiz, I think everyone assumes that the amp was playing while he disconnected the ground

[Duran 387]

When you remove the negative cable from the battery you don't have a complete circuit, then there is still a complete circuit (like when the negative cable is still connected to the battery) and you remove the ground wire, obviously you don't have a complete circuit anymore, but you are just asking for a blown amp. Touch a screwdriver, or anything metal to the amp frame. and you'll have yourself a new paperweight.

[shizzzon 461]

u can't have a complete circuit if you remove the ground off the battery because the ground has been removed out of the car. When you remove that wire, u can sit there and touch the power and ground to each other all day long on the amp and nothing will happen.

I don't really understand why you guys think it's so bad to do this because back when i first got started in audio several years ago, lots of manuals to equipment i bought always said to install ground wire last so that's what users would do.

But he hadn't disconnected the negative on the battery as evidenced by his second post saying it sparked when he put the ground back on.

No shit?? Read closer at what I said.

well as you described in the title a word to explain the amplifier "POS" that's probably your problem right there.
