So, I have an infinity basslink system in the back. I installed it about 5-6 months ago. Power comes from a 12 gauge wire through the car. The radio has a dedicated subwoofer mono outlet, so I have a 1->2 rca splitter. The sub has worked fine until up to about a couple weeks ago. It just won't boom like it used to. I've checked and rechecked the ground, both fuses, all rca connections, settings on the head unit, etc. The servo led still blinks on the system so i know it is getting audio input but there is no bass.

cliff notes: sub doesn't work, sub gets power, all connections good, joey is sad

HELP??A?@?!??!?!

I have the bass link 2... and it did this when one of the RCA's was unplugged. I'd start there. Perhaps the 1->2 adapter is unhappy.

Really really am pleased with this box otherwise, though.

EDIT: Also... unplug the deck completely and let it sit for a few minutes and plug it back in. Had a fluke with the stock radio after someone attempted to jump their car with the cables backwards to mine. :-/

That must be one small amp setup if you're running 12 gauge. I'm running 4 gauge on mine but then again i'm running 2 amps that claim to push 800w RMS. If you've heard of Steve Meade (famous for his Tahoe on youtube) i remember him saying that If you can take the sub out of the box, a simple way to test if it isn't fried is by hooking up your cars battery directly to the (+) and (-) terminals on the sub. Don't leave it connected though, just quickly connect it and disconnect it. If the sub moves then its still good.

the sub is one piece with the amp. i played around with the rca cables and they come on after a while. it is very temperamental. it worked this morning driving home from office depot. but not on the way to office depot...weird

Little overkill there?
Good idea, but a little over the top on the power source, IMHO.
Kinda like weeding your lawn with a cruise missile...
You can do the same thing with a AA battery and save yourself some trouble.
Going with a small speaker popper is MUCH easier and there's no risk of smoking a voice coil.

meh works solidly now..

i got a new battery a couple days ago. i think it just wasn't getting enough power to the coil/amp

I'd run a bigger gauge wire. 10 gauge at least but 8 would probably be better. Should help with your amp getting power. Crutchfield has a list of recommended gauges depending on your current draw and length of wire. I believe 12volt has one too.

Hey i'm just saying what that guy said on youtube. He does know his stuff by the way but you do have a point using a AA for simplicity's sake.

Just throwing it out there... Hate to see good speakers get wasted.
A battery will smoke a voice coil wit da quickness!

Wanna have some fun? Find a toasted one and time it...
Back in the day, we'd sit around the shop for a few beers after work on
a friday night and perform the "AC Voice Coil Test" on thrashed woofers.

All you need is a plain old 120 volt power cord with a couple
of alligator clip on the business end and You can make smoke TOO!
A good quality woofer will give you a 60 hz hum for a while before the smoke comes out...
Little speakers go even faster!

Ahhh - Good Times...
