I have a newly purchased 2010 LS with 2.2 just the base line Radio I think. 4 full range adn I think 2 tweeters in the pillars. I am looking for the specs as to how much wattage the radio puts out per channel, so I know what I am dealing with and how much more i need to go to improve it. I am thinking of going with Kenwood S in the doors and pillar, and maybe a Kicker sub and amp where the Premium sound systems sub is located that I dont have. Any help would be greatly apreciated.

 

Use the stock radio for control only...amp and speaker it the way you want after.
Doubt you have enuf to drive the Kenwoods and have em sound good with any kind of volume with the stock radio only.
Read ALL the threads here and you'll see the pattern.....

 

Thank you for your advice. 8-D
