Powered sub install questions

Recommended Posts

CT99ResponseLX

I started the install of my powered sub tonight and double and triple checked the wiring and its good from what i can tell. I know enough to be dangerous. I have the power lead, the ground, the remote wire and the signal rc wires from the head unit all connected. The red power light is on but im not getting any sound from the sub.. I checked the sub settings on the head unit and its on. I adjusted the gain, and settings but still nothing. What am i missing?

Got any pics? Which powered sub is it?

Assuming it's one unit. Check the sub connections.

Just a shot in the dark, what head unit are you running? On my JBL black box you can enable/disable the subwoofer RCA outputs in the settings.

Ive played with the sub settings in the head unit and still cant get sound. The boat is still blocked in the garage, i may wait until i put it back on the trailer and drop it off at my local shop to troubleshoot and complete the install.. I jave plenty of other projects to complete before we ski so i can focus on that. The head unit and speakers are night and day difference already. Thanks.

The gain on the sub/amp would have been my guess, but it sounds like you already tried that. It's a long shot, but have you tried another pair of RCA cables from the head unit. They do go bad from time to time, or pinched and cut during installs.

If you just wanna see if the box will make any noise at all, eliminate your head unit as a source. Get a 3.5mm-RCA cable and hook it to your phone/ipod directly. Keep the B+ power and ground hooked up and keep the head unit on if needed to supply your remote turn-on power. You can always just run a short jumper from your B+ terminal to your remote terminal also if you suspect that may be an issue also. A test light or volt meter may come in handy if you know how to use one in checking your power/ground supplies . this will tell you for sure if the equipment is good, or if it is soemthing outside of it casuing your problem.
