Ok so im getting ready to upgrade my stereo system in the FJ...I know that there are live wires behind the blank panels in the rear of the truck so I was planning on cutting holes and wiring up 6in speakers...but what size goes in the doors...everywhere I go I get a different response, 5 by 9, 5 1/2, 6...so what is the stock size, and the tiny speakers in the dash, are those just tweeters or little speakers...any input is appreciated thank.
