Problem for Infinity BASSLINK Car Subwoofer

My sub woofer wont turn back on




By austin_opitz on Oct 14, 2009

" "
I have an Infinity Basslink subwoofer in my 2002 accord hooked up to speaker level input. It has been in there for nine months and I have had no problems with it. Just the other day, though, I was towards the end of a 2 hour road trip when my sub just turned off and will not power back on. When i jumper the Battery terminal on the back of the amp to the REM terminal, the sub powers up and sounds like normal. I called Crutchfield support and they determined that the auto-turn on was not working so they had me send it back and they sent me a replacement. I am having the exact same problem with the replacement so i assume the problem must be in my car.

Hello austin_optiz,

If you have had 2 units with the same problem, I'd say that yes, there is a problem with the "sound sensing" function of the auto turn-on circuit. Either it's not getting the correct level or one side is being shorted or grounded. Some vehicle speakers may have one side at ground potential which could cause the auto turn-on to fail.

If the Basslink operates normally otherwise, I'd recommend that you just connect a 12V + fused and switched source to the remote terminal. Wire it through a conveniently mounted toggle switch and turn it on and off manually.

Hope this helps.
