I know this thread is a few years old now but hopefully still active: If I go for a basic Pioneer head unit, designed to work with 4 speakers + Bass...how do I get power to front dash speakers and rear headliner speaker? I haven't ripped into my dash yet but I'm assuming the stock amp provides the add'l power to all these speakers? Related can you add link to the "tons of posts" re removing stock amp? Can't find anything in search. Thx!
not sure about - Toyota OEM quality -
here is the free "kit pocket" from Crutchfield that comes with a H/u purchase
no complaints on my part....
replacement of the h/u and stock speakers is fairly rudimentary (remove stock amp is a must) - tons and tons of posts (of which I have contributed on)
if you need more 1:1 direction - simply shoot me a PM
