Awesome ride ....... How did you go getting the wiring in for the power / negative ground in through the firewall ?

also with regards to the head unit to factory speakers ( assuming you still are using your factory front and rear speakers ) wii g, how did you go there ?

i still have my factory double din unit and am torn between buying a single din unit like yours and going that way to run my rear factory speakers and run the front splits ( awesome aftermarket pioneer ones ) and the rockford punch amp and my subwoofer off the head unit via its RCA pre-outs

Any tips from you please would be greatly appreciated
