Sub Wiring Help Options

[Nick205]

I am putting an Infinity Basslink powered sub in the trunk of my celica. But the sub will not power on. I used a voltmeter and the sub has power going to it but it won't power on. However when I put the positive battery cable in the remote spot on the sub it will power on. Is it safe to run it with the battery cable in the remote spot? Can I run the remote cable and the power cable at the same time? Please help!!!!

A lot of head units have a wire designated as "remote" and it is often blue or blue with a white stripe (at least from all the decks I've used). All the remote line does is send a low power signal to the amplifier that tells it "the cd player was turned on" so the amp will power up. The signal is like 1/4 or 1/2 an amp and if you put your positive battery connection to that, you probably won't like the result.

As it was pointed out, you don't WANT the sub to be on constantly, you want it to go on and off with the cd player (what you called auto on/off feature), so you need to use the remote line from the head unit to the amp, not from your power antenna.
