I am looking at upgrading the Head-Unit on my 08 Mazda 5 GT to a Pioneer AViC-F90BT along with complementing speaker/bass/amp upgrades. Would having the car Dynamated prior to upgrades introduce problems in wiring and speaker installs? The car is a daily highway driver and I would like to reduce the noise in the car's interior asap. However, not at the risk of limiting future stereo upgrade plans.
