Toyota 86 Car Audio Upgrade
 

Hello, Just needing some advice, i want to upgrade the 2 rear 2 door and the tweeters, also i would like to run them from an amp under the passenger seat + an amp in the boot to run a subwoofer,

Is there any tutorials on how to do this, ive found a few on removing door trims but thats it, also what size tweeters, rear and front speakers will i need, and the depth.

Thankyou
