>>> Here are my thoughts,
My standard system is the sorriest sound system ever put in any car period.
I want the car to remain visually stock..(I am 55 years old!!!)
Here are my thoughts..***** a complete set of L7 speakers.....change all door units to better L7 speakers......install rear deck speakers and power them with a separate amp...high/low connector off ASK unit.
