    GMT900 Bose Premium Amp to Luxury Amp Upgrade

    Scott, thank you so much for the very detailed write up. . . you've saved others so much work! I always puzzled over why my Silverado's Bose system doesn't sound nearly as impressive as Bose systems I've had in Corvettes. Would it be too much trouble to get the P/N from you for the "plug and...
