Ok I have a 2004 Crossfire and just installed a new JVC head unit with the Scosche vwo1b and it works great, thanks for all your work!

I am using the factory amp to power the 2 rear subs and it sounds good, very good and its scary. I also want to add a new amplifier to power additional 12" subs in the trunk. My question is, do I just splice into the antenna at the wiring harness (blue wire) and run that into my new amplifier. Dont want to run into any problems here.

If you can also tell me how to run my 4 gauge wire from the battery to the trunk without running into too many problems. Thanks for your help in advance.
