As the subject states I’m interested in installing a car stereo system in a 2009 Chevrolet Silverado, Crew Cab, 5.3 L with Bose Audio System. I’ve never installed a car stereo system. However, I am handy and I’m confident I possess enough knowledge and tools to achieve my goal. I would like to keep my factory ‘sounds,’ i.e. door chimes, turn signal, etc. In addition, I would like to keep my Sirius XM and Onstar active. I have decided on a head unit, the Kenwood DNX7190HD. At the minimum I would like to add two 10” subwoofers and an amplifier. I’m indecisive as to whether or not I should replace my factory installed Bose Speakers. Please provide me with input. Anyhow, below is a parts list based on the research I’ve done thus far. I don’t intend to sound arrogant, but money isn’t an issue. I would like to purchased quality materials and conduct a clean install. Please provide me suggestions for the subwoofers and amp. Any direction provided would be appreciated. 1.

Steering Wheel Controls – At this moment I do not have any audio controls on my steering wheel. I’ve considered adding them, however from past research it would be ideal to replace the steering wheel with one that has audio controls rather than buying buttons and having to deal with customizing the steering wheel wiring harness. 10.
