So I have the base sound system without a stock amp and I couldn't find the these wires

SUB LEFT
Red/White +
Brown/Yellow -

SUB RIGHT
Red/Blue +
Brown/White -

So my question is, what wires do I tap into for the sub to LOC convertor? I tried searching all over and couldn't find what wire to tap to. I'm looking around the harness that connects to the Idrive computer.??

please help

When I did this in my e82, I tapped directly into the sub lines and went bypassed the high to low line converter and got very poor bass notes (remedied this by installing an aftermarket deck and installing directly from the deck) so would adding that high-low level converter mean that I get more bass, like when I hooked up a custom head unit?

If you have a new head unit that has RCA outputs for sub, connecting these directly to your sub amp is all you need to do. RCA jacks are LOW LEVEL outputs, speaker wire outputs have are HIGH LEVEL, thus if you just tap into speaker wires and try to put into amp it'll be all distorted, thats why you need a Hight/Low level converter that converts that signal back to LOW Level outputs that your amp can now use with lower distortion.

If you use the RCA outs to a sub amp and sounds terrible, chances are its your Sub Woofer / sub box set up. Make sure cross over point is like 80hz and down to the sub.

Hope this helps
