Trouble shooting ideas for why my subs don't work

4x4Hemi · Sep 7, 2012

Okay so i got my subs and amp in my truck. and their just not getting any power! my amp is getting power as the light turns on, but the subs get nothing... I've checked all the wires and their all good, made sure negative to negative, and positive to positive... the RCA's hooked up right and the REM is good because obviously my amp is turning on... I can't figure it out and its really bumming me out. Any ideas??

double check them man, rcas might be bad also

4x4Hemi · Sep 7, 2012

i double checked and triple checked em.

is all the wiring new??? you using a LOC??? or on a aftermarket head?? if aftermarket make sure your sub volume is up

4x4Hemi · Sep 7, 2012

I got a new headunit. So your saying there's something on my headunit to turn the volume up on my subs haha what?

possibly. I know on mine there is a spot where I can turn the sub off.

Check your settings, could be that!

GhostRam94 · Sep 7, 2012

yep i would go through all the settings and mess with them cause that might be it

is it a new amp or used?

4x4Hemi · Sep 7, 2012

Its a used amp and he put all the wiring he had in his into mine. Could that be the problem?? I can't find a setting where I can turn the sub off... Does it just say "sub off" haha I looked through it all

GhostRam94 · Sep 7, 2012

you might have a bad amp.... try another set of rcas...

Same thing happened when I sold my subs, check the RCAs and try putting them into the left and right RCA on the deck instead of the sub out. Turns out the guys RCA port for sub was warped and not making direct contact to play subs. Oh and check sub wiring inside of box and make sure they are plugged in.

You losing signal not power

4x4Hemi · Sep 7, 2012

okay ill try out the RCA, like i can just switch them between the other ones? i know theres ones for video and stuff, i can just switch those around it doesn't matter if its the specific sub ones? it also very possible its his RCA wire.

Yeah usually there is a second set of RCA plugs, they are assigned to send the signal. If you get a signal you know it's the RCA sub out or maybe the RCA wire itself

Looks to me like theres only one for subs

bigbadram1500 · Sep 7, 2012

popped this over to audio since it is covering subs and amps.

glass3222 · Sep 7, 2012

what kind of amp? How many subs? Need specs

glass3222 · Sep 7, 2012

also, negative amp input should go to chassis ground not negative battery terminal. It should be as short of a wire as possible, most recommend less than 30 inches

4x4Hemi · Sep 8, 2012

okay ill do that to see if it helps,

Its an Alpine mrp m1000 amp power 2 12" alpine type r 1222
