i have an 07 classic.

I got a aftermarket stereo for my birthday.

Was on crutchfield.com looking up harnesses for it.

They asked if the truck had 4 or 6 speakers.

The truck does not have onstar or bose system.

Has 4 speakers in the doors. But i see tweeters in there also are they counting the tweeters also?

Or would if just be a 4 speaker system?

that would be 4 i have same truck and bestbuy carries the harness as well as auto parts stores
