one of the cables must be connect to the battery, that s what keeps the memory. I believe you must take it to an electrician as the wiring varies.

I need the wires to conect my infinity basslink 10''


Any auto parts store or WalMart will sell adequate speaker wires. For a sub of this power rating, you'll be fine with 14GA speaker wires (pronounced 14 gauge) but if you want to get beefier wires in case you upgrade the sub later, I'd recommend this 10GA hookup kit or something comparable.

My sub woofer wont turn back on


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.

You have an internal problem in the amplifier of the sub woofer box. You need to take it in to be checked at a service center, there are no quick fixes for them. Sorry,

Infinity Basslink killing battery


Both issues sound like they are related to a non-connected or loosely connected remote wire on the Basslink.

If you're using RCA preamp wires to connect your stereo to the Basslink, make sure the remote wire input on the Basslink is solidly connected to the stereo's remote output.

If you're using the speaker level inputs on the Basslink and not the RCA preamps, make sure the remote input is not connected, as the Basslink will automatically turn on when it senses the speaker level inputs are active.

Power light


Hi Bill, I believe the power problem is related to the Remote wire which should be blue or yellow. The remote wire is suppose the turn the Basslink on and off when the radio is turned on and off. The yellow wire is normally used for power antenna. Traditionally the remote wire is blue. You can use a Speaker level adapter and splice in with the L/R rear speaker wires, and the adapter will convert the speaker level to line level. The output of the adapter will go to the Rear speaker input on the basslink., Write back if you need more detail on the adapter.
