What is the Scion Warrantee after installing speakers, amp or subwoofer? Has anyone had any issues with Scion once they installed aftermarket speakers or amplifiers?
As far as I know, the only time you would have trouble with a warranty is when you have a claim against it. I haven't seen any problems on the forum concerning the sound system.
