I recently changed out the head unit to an after market one on my 06 Scion tC. I loved the way the car sounded stock I always had mine set to feel and all normal settings. I was just wondering if anyone could recommend a set up that would get me close to that? I knew what my speakers could handle with the stock radio and don't want to surpass that on my new radio. Don't want to blow my door speakers by being dumb is all. Thank you!
