[QUOTE="fmueller67, post: 8721035, member: 681394"] Hi Everybody, first of all, many thanks for admitting me to the forum. I used to be into car audio way back in the mid 1980s to early 1990s. In the interim I moved around a lot, didn't have time to work on a car, and I was reasonably happy with the stock systems in my cars. They have got better! Recently I bought a Corolla Fielder, which is a car that's not available in either Europe or the USA. We get it here in New Zealand, because most of our cars come 2nd hand from Japan. Anyway, it had the worst audio system I ever listened to - just two paper light speakers in the front doors. For the reverse camera the dealer had already installed a new head unit, which I kept. I upgraded the system to this: Head Unit: Nakamichi NA3600M Amplifier: Sansui SA-31504 Front doors: Rockford Fosgate R165x3 Prime Series 6.5" Rear doors: Rockford Fosgate R165x3 Prime Series 6.5" Dash board: Nakamichi 13mm tweeter pair with crossover Subwoofer: Fusion CPAS1080 active 8" slim underseat subwoofer I am pretty happy with that setup, but my question is about the tweeters.
