Ok, a little background.
I FINALLY installed my subwoofer set up. I hate revealing details, so i won't. But it worked great. I'm running it from an Alpine 9856 headunit to a mono amplifier to a 10" subwoofer. Worked GREAT.
So i turned my truck on, and i turned on my tunes... and i don't hear my sub. So i check all the wiring (new wiring, tends to fall out.. etc.) everything's good. I thought it might be the wire on the sub shorting out. I checked out, it's all good. Then, i pulled the RCA off of the amp, and it gives me a green light (that's good). I'm like, wtf right?
So i plugged the RCA cables back in (red light!! BAADD) and on my headunit, unplugged the RCA's.. green. (good!). So um... i thought, hell, it's the damn RCA cables! I go to radio shack, got brand new ones, plugged it in. RED (BAADDD).
So... what's up? I don't think it's the amp, because the green light still comes on when the RCA is unplugged. It *might* be my headunit, but that's ok, because i have warranty on that. Any other things i should look for? I'm using all MONSTER cables and the amp/sub setup is perfect for each other (nothing's overpowering/underpowering).
Help? i'm kinda disappointed in myself...
