Hey all! New here and I would like to say hello! Also need some help if anyone wouldn't mind. I built a tline enclosure for my wives 2013 1lt equinox, it is housing a single American Bass XD 6.54" subwoofer. Running it off a single RE Audio 600.2 DTX... I started tearing into this Equinox this morning and quickly noticed it's pretty different from any other car I have worked on. Could anyone maybe help me out by giving me and idea where they ran there amp wires through the firewall? Also if anyone used a line out convertor could anyone give me some info on how to wire this convertor to the MYlink radio? I hear there is a factory amplifier that you are supposed to wire the convertor into before the signal is amplified, I can't seem to find this amp either though? Any help is greatly greatly appreciated!
