Congrats, keep us posted on how the audio install goes! If it works out I may follow in your steps.
Okay - just got her back from my stereo guy. The center dash speaker completely blown as was the back woofer - it was cracked and someone tried to glue it LOFL and finally just cut the wires. He disconnected the two front center mids and dash center speaker as he deemed them as worthless.
He installed a JL 4 channel amp and 6x9 Infinity Kappa fronts and Kappa back seat 6.5 and a 6" woofer in the cargo bay. The result greatly exceeded my expectations. My guy is George @ Mobile Electronics 10100 Clay Road in Houston 713-460-2555 - He does business with Javier whom many folks in Houston know well.
George also installed HID low beam and fog light kits which greatly improved the lights.
Interestingly he confirmed that the ML is pure garbage.
