I have the OEM speakers 4 ohm & 15w along with the Mit factory amp under the pass seat and the AVIC-Z2 says less than 50w speakers are no good. If I keep the OEM speakers do I also wire in the Mit amp into the Z2?

I'm planning to install a AVIC-Z2 in my 1995 Spyder VR-4. Looks like I have to replace all 6 speakers. Can some 3000GT owners tell me what you replaced them with, did you do it yourself, how did it work out? Thanks.
