Whats up guys, so I got a Z2 for my Gs300, and I currently have a after market amp installed in the trunk for my subs. I still use the factory amp, and cd changer, but obviously am going to lose that once installed. My questions pretty straight forward, ive seen a few methods of installing the head unit and by passing the factory amp Via making a harness with two of the Metra 70-1761 kits, one at the stock amps end, and the other to plug "directly" into the avics harness... sounds simple right? pretty straight forward? well, yea, not when you got this all, and know almost nothing about radio installs, besides the basics of installing an amp and subs. I did not install the current set up I have, I got it professionally done, which like I mentioned, still utiliZes my stock speakers, amp, and CD changer in the glove box, but no longer uses my stock sub which I removed. Heres some pics of what im working with, if anyone could give me any intel id greatly appretiate it, I am left with a mess (to me it looks like) of wires and dont know what should be used, and what possibly shouldnt. Ive included pics of what im "supposed" to make as well if it will help you understand. IF YOU OWN A LEXUS GS300 AND CAN HELP ME! I have a spare 2000 platinum edition ive been parting out, I WILL GIVE YOU INTERIOR OR IF I HAVE WHAT YOU MAY NEED! FOR FREE IN RETURN IN APPRETIATION!
So here it goes:

MY AMP AND SUBS, I believe he used a line out converter from the original sub for the new amp in the trunk.
