In my 2001 Cobra I have the Mach system with a Kenwood Deck. It appears that the Speakers are still being amplified by the mach system. I am going to upgrade in pairs so I am thinking of to wiring the speakers straight to the deck which is a 52x4 watt deck. I am sure i need an aftermarket amplifier but what do you guys think? Will the sound be drastically different front to back if I do it this way?
