Notes:

Discounts for doing multiple mods at a time.. Half the battle is splitting it open, so doing everything while its disassembled saves time..

A lot of these require cutting, drilling. modifying chassis or amp in some form. I try to be as discrete as possible many cases you can revert back to factory with out knowing it was ever altered. If I remove old parts I save them for you so you can tuck them away.
