What have you crew cab owners got as far as after market tunes in these things?
Other than the dash speakers, what other factory locations? Waaaaay waaaaaaay back in the day, 15+ years ago, I had an '85 K30 single cab srw. It had factory speakers right behind the seat on the B pillar. Do crew cabs have the same? With the '85, I was able to fit two small truck boxes with 8's behind the seat. What about the crews? Is there enough room behind the seat for the same style box? Could 10's be crammed back there? Any other options for subs?
