Well i am in love with the scion that i just picked up one week ago...this is my first post here!!!! Any way i was wondering i have the pioneer six disc changer head unit in there and want to put some subs in there, is it possible to upgrade the factory head unit and put the subs in the storeage compartment, i have some MTX road thunders that are good for free air usage. but i don't know about the wiring for the amp particularly the RCA and RMS. Any links or suggestions would be much appreciated.

 

Welcome to Scion Life and congrats on your purchase. Great choice of color too!!! Yes, you can upgrade your factory HU. Click on the link to see how I upgraded my system. Be sure to send me a PM if you have any questions.
