Speakers Brands: Quality,Price,Installation

[frankie257]

Hi, I have been wondering to possibly upgrade my front door and rear deck speakers. I know that the front door speakers are 4 x 6 and the rear deck speakers are 6 x 9. The brands that I have narrowed down to are either Kenwood or Pioneer speakers. I want to know which of the brands has better quality for these size speakers and cheaper price. Also I pretty much know how to replace the front door speakers but, I really don't know how to replace the rear deck speakers. A list of tools needed would also help out a lot. All comments are appreciated. Thank you.
