Hey guys, I hope I am not asking the same old same old, but I have a couple of questions about adding a powered sub to the 01 Symphony stock system.

All I found in the Tech articles was adding to the Bose system, so of course my first question is can it be done?

If so, how? I bought the line-level converter and a basic monster sub wiring kit thinking I could do it with the symphony system. Was I wrong?

Thanks in advance.

Maybe the easiest hookup is to wire directly to the rear speakers if you have a speaker level input or converter. That is what I did:

You can also tap into the line level signals going into the rear amp (mounted on the drivers side reas speaker). I looked the wire colors up for someone recently but am not at home so dont have the colors. Seems like the l/r hot were blue wires, one with a red trace and one with a green trace. The RTO is white, and the signal grounds are brown (both have a trace colors too but they tie to the same connector on the amp). Be sure you run separate 12V and ground. Dont reuse the amps 12V and ground.

Also europeanspeed.com has an article on installing a sub.
