5000 turbo 10-speaker system ?'s

[Ameer Antar]

Hey all, I picked up a set of door panels from a 5ktq which has the 10-speaker system in it. They don't look like Bose speakers (they say ITT like the normal dash and rear panel speakers). It looks like there's a crossover on the front door panels but none for the rear ones. I assume on the front ones, the smaller driver is a tweeter, the other a woofer. The rear door panels have only one smaller driver, so I assume it's a tweeter. So should there be a crossover to stop the low frequencies from going to these rear door tweeters, or are they really full-range drivers? Were these tweeters designed to split the signal using a crossover with the speakers in the rear deck? How many watts can I put into these door drivers? I was thinking of possibly using the head-unit's built-in amp for the doors and then getting an amp for the front dash and rear deck speakers. Any recommendations or advice?? Thanks in advance.
