you should put your rcas into your input instead of output on the amp lmao

HAHA LMAO at you not him. He meant on the sub outs in the headunit not the amp. //content.invisioncic.com/y282845/emoticons/graduate.gif.d982460be9f153bb54e5d4cb744f6ae8.gif Schooled.

okay i just tried a brand new pair of RCA and it didn't solve anything. I have a multi meter and i'm going to try that.

 

[wcarson8911 10+ year member]

will someone help me with this multi meter..i'm pretty confused...AC or DC? 2V or 20V ? should i test the sub leads or the amp leads?

AC voltage at the speaker terminals if you have if its digital i hope its an auto ranging dmm...if not then set it to 2v and turn the volume all the way down and turn it up and down slowly if the voltage moves with the volume its not the amp or rcas as you have output...or you could take a tone generator or 9v battery or drill battery and tone the subwoofer whichever works for your

okay i figured out the multimeter and the amp speaker outputs are working, the voltage is increasing and decreasing with the volume., My guess is the sub is messed up but what is the problem?

wait i thought AC was for in home stuff. And DC was for cars? i used DC and it was going up and down

EDIT

i used the AC and it increased when the volume increased. How can i check the sub?

meter the coils first....then test via tone generator, 9v battery or drill battery

audio signals are AC signals

explain the subwoofer tests more indepth please

Try another speaker/sub, you just connect any extra one you have. Just to see if it works. Is the gain turned up? Have you checked the features on the hu to see if the subwoofer is on?

 

[wcarson8911 10+ year member]

is there any way to see if the RCA inputs on the amp are messed up?

I'm not sure how. You can try another amp and see if the sub turns on. That amp should be in good working condition. It can't be the rca inputs, I've never had a problem it before.

ac=audio current? man i thought dc= direct current as it directly from the battery? i need to learn about my dmm i thought i knew how to use it but obviously i have no idea.
