Just got (4) 6.5 inch aluminum cone top of the line Sony Xplodes to replace the stock cabin speakers and (1) 12 inch Xplode Sub for the trunk with a 600 watt Sony Amp. How hard do you guys think it will be to wire all the speakers & sub on the new amp and bypass the premium sound stock amp? I've done all my other installs myself and I would like to do this one also... give me some tips cause I'm not too familiar with audio installs.
