Hi All,

After hearing the Mark Levinson system in my fiancée's new lexus, i have decided its time to rip out the crappy BO system.

After countless hours of reading threads here, i would like to consolidate what i have found and get feedback for my relatively simple plan. I am attaching a wiring diagram of what i plan to do based on the the information i have gathered from here.

System wise, the only things i have decided on are:

Amp: JL VX 1000/5 (love the simplicity of having one unit (amp+dsp) to handle all speakers (75rms x 4 + 600 sub)

Zen interface

Potentially a Jl sub that will bit under the back seat (the single flip up one). Open to suggestions

Have not decided on components yet- will get to that later

Below is what i have gathered from all my research-

  • Run 4 ga power and ground from battery through smaller grommet on passenger side with distribution block in rear
  • Run new wires for tweeters to back
  • Using this harness: Speaker Connection Harness - PAC (pac-audio.com) connect the stock BO wire to the harness and then connect the harness to the ZEN
  • This allows Can HI/LO to the Zen and peels off the speak wire for easy connection
  • Power/ground Zen through distro blocks- DO NOT use stock wiring
  • Zen to Amp via toslink
  • Wires from pac harness to passive crossovers
  • Speaker out wires from amp to crossovers and sub
Please see diagram below- This is what i am thinking conceptually based on all of the research.. Any feed back or things that i am missing? Thank you!!

here, on frf
the one downfall with the dsp amps is lack of power. doesnt matter who makes it, you lose dynamic headroom. most people will be ok with it, but if you listen to music with complicated orchistral passes, you will notice. the jl amp can accept 2ga, so i suggest using that instead of 4ga. also a 5 channel amp does not allow for an active front stage so you will not be able to tune the system as good as it could be. (unless you use the amp for the front stage only).as far a subwoofer, there are better subs available that will work in a small space. with the amount of power you are using, the oem wire is fine. no need to run new wires, unless you want to.

overall, you will be much happier with your setup, just remember you can greatly improve your sound quality for a little bit more, by going to an active front stage.
