Hey everyone i'm new to the forums so please work with me.lol. My e60 is on 20'' 3 piece D-forged wheels.They are all chrome but I was thinking of changing the lip to a polished or machine look and the face the same silver as my car?Opinion's are welcome.Also I just have the basic sound system and was thinking of putting some Mb quart qsd 213's in the front and mb quart pvf 213's in rear.I have a kicker 350.4 amp for the speaker's and a kicker 1000.1 for my 12'' kicker cvx's.Also I bought a audiocontrol lc7 for the radio. Now the problem with the system is I went to a audio place called audio shoppe and the installer was saying that installing a system would be a lot of work due to the fiber optic wiring? Also might void the warranty? Just the labor alone was 5k.Audio shoppe is considered one of the best audio places in SO CAL.
