so yeah, i have an 09 gts with everything you can get from the manufacture on it. i love it. but i wanna add a 12 kenwood that i have instead of the 10'' that it comes with. how do you do it? i'v thought 'bout just taking the speaker off but when i did i just found alot of wires and not just regular speaker wire. any tips or suggestions on what to do?
thanks

I also want to replace the factory sub with an aftermarket and add an amp to power it. This is with navi. i'm thinking if you wire the power and ground cables like normal, then tap into the existing "RCA" on the factory harness and wire the remote into the ignition somehow, that that would work....but this is just a thought. I haven't actually done anything but I want to.

has anybody with navi done this? there must be someone who has. Thanks!
