I had my amp and sub out of my truck t he past few days cuz i needed to use my cab and i went to put it in tonight and its not doing right...every time i change the song it rumbles and sratches...and on my HU i can turn my sub on and off but when its off its still on and never done it before??? plus my amp is only pushing maybe half the power it did...i checked my grounds and even checked wiring on the speaker and everything, its all still the same? whats going on? anyone have any clue its really got me pissed off, oh and its a kicker cvr 10 and a kicker 200x2 amp

 

and now it plays fine with only one rca hooked up..if the other is connected the amp goes into protection mode, it still does the rumbling though...

 

RCAs reversed? dont think so b.c. it wouldnt play anything. CHECK YOUR GROUNDS AGAIN.

 

i have the amp grounded to my passenger seat bolt with the paint grinded off, is there a better place to ground it at? i played with the rcas and it does it either way, even on the output side of the amp

 

There are but it wont matter thats where mine is. Ill have to think about it.

 

LOL, got me baffled...

 

amp might be fried

 

it pushes full power with one rca though....when the other is hooked it goes in and outta protection mode, its really bothering me

 

Check the fuses on the amp. The amp I have running my midranges has two fuses and one was blown and it did the same thing you're describing.

 

mine is only one fuse and its a 30amp, and its fine i just went and checked

 

1. Check to see that you have power wire hooked up to power and remote hooked up to remote and not the other way around.
2. If your wires are run underneath the carpet check to see that one of them didn't get smashed by whatever you put in your cab.

 

they are under my carpet, and wires are ran the right way, i went threw that last night lol, i will go pull them out from under the carpet and check, i would not of thought of that one

 

make sure you didnt rip/tear/etc the rca wire

your getting noise in the system somewhere, all you did was rehook up the amp, not add anythings?

 

yea all i did was put everything back in, its the same stuff i had for 3 months now and never had a problem out of it til now, the rcas are fine, i just pulled them outta the truck and looked, besides being cheap walmart ones they are fine

 

It sounds to me like a bad head unit. I would say bad amp, however, the amp functions fine until you switch stations or songs. Is the head unit a cheap walmart one as well?

 

its a pioneer DEH-3900 the 06 model, i had it for about 7 months, its only problem is it dont spit the cds out all the, never had a problem besides that, but im starting to think it is the problem, it does it on all 3 sets of pre amps too,
