Grab a DMM and start checking voltages. Make sure you've got 12v on the amp's + and remote terminals. Then if they do have power to them, check to see if your getting any voltage out of the amp.

If his amp powers on he is getting power to the amp and remote. Check speaker outputs for power and check sub with DMM

duh, I must have missed that

what should the sub read?

what voice coil configuration do you have dead president?

NVM Saw it in your sig. Should be around 1 ohm usually alittle under to acount for rise.

If you pull the sub out and put a DMM on the coils you'll know right away if it's blown. Usually they blow open so you won't get any kind of reading at all, it just read like an open circuit. (Or some very high value).

i just bought a dmm but i dont know how to use one lol

my speaker outputs aren't reading anything

how hard were you pushing your sub. that amp can smoke that sub if you clip the amp hard

 

[beyondrepa1r 10+ year member]

well my speaker outputs on the amp i cant check the sub right now since its raining outside right now i wasnt pushing it that hard

anyone?

to check the amp output:

set DMM to VAC and put red and black DMM leads on amplifier speaker output (+) and (-) terminals, respectively.

to check sub resistance:

disconnect speaker/sub wires from amp. put red and black DMM leads on sub/speaker (+) and (-) wires, respectively.

if you get an O.L. or open reading then you have a blown sub or loose connection - remove the subs and test the terminals/check the wiring. if you get just under 1ohm then your sub wiring should be fine.

i figured out how to use it but the speaker outputs arent reading anything
