Hey everyone I recently bought a 2000 mustang that came with an aftermarket kenwood headunit. It has a mach 460 sound system but the speakers are very staticky. The front driver side speaker does not play at all nor does the tweeter.. I want to install two new speakers in the front and add an amp with 12" sub in the trunk.. Will I be able to use the mach460 wiring for my 6x8 speakers? Or will the amps present a problem? Thanks!
