they are 4X6, 2 way, but I bought the new Pioneer 4X6X3, and man they kick rear!
Around 215 220hp.
From a Chevy Dealer.
In the throttle body.
4L60-E or 4L80-E.
I believe it is a turbo 400
off the driver side exhuast manifold
the stock speakers are 4x6 inches
Should be in a removable housing at the engine end of the upper radiator hose
Take the inside of the glove box out and look in and down to the right and you will see it.
they dont ship stock with rear speakers.
NO. Not even close.
It calls for a 195 degree T-stat.
