I'd like to know this as well
Doing some google research netted the following: 4x25 + 1x50 and speaker level signal to sub with a low pass xover.
I believe both is related to the Bose Luxury amp not the Premium in lower models of GM trucks.
“- Amplifier is 150 watts (4 x 25 watts = 100, 50 watts for woofer).
- The front and rear speakers are 25 watts each
- Woofer is in a 7 1/2 liter bass box. 5 1/4 inch woofer in bass box. -”
And
“The radio/preamp does not have any "sub outputs"... It sends full range rear and front left and right audio signals to the amp and the amp uses its built-in cross over to determine which frequencies should go to the sub and which go to the speakers. There is no high-frequency cross over for the tweeters. Bose just wires the tweeters in parallel with the front door speakers and then puts a capaciter on the tweeter to kinda give it a "poor man's cross over". The capacitor roughly cuts lower frequencies so the tweeter doesnt blow. The sub on the other hand, as I said before, DOES actually get a "real" cross over that is internal to the amp. ”
