jl audio has the speaker to rca cable for sale now on their website under audio accesories 12.95!! You use this cable to add a sub directly from the factory sub wires there is NO need for a loc or remote wire!! You can use this cable to run from the tl sub to the amp and not run a remote wire since the jl amps use signal sensing for turn on !!

this will work on any JL amp? or jus 250/1 500/1 ?

 

Not sure about the other jl amps the 200/1 and 500/1 are the only ones i have delt with! You can search the amps on the jl site to see if any others use signal sensing technology!

 

amps with signal sensing only are capable of this application

 

Sort of...
I'm using a JL e1200, and it DOES require a switched power source to turn the amp on, but it also supports high level input. Just run the existing sub wires to the amp input.

 

Yup...you could run a remote wire for your amp turn-on from fuse 32 on the fuse block, or run that same remote line from a relay, if you're turning on multiple devices.

Lots of JL amps support line-level inputs...I'm running a 500/1 and a 350/4.
