Thanks Mark! Objective here was to keep it inexpensive. Fixing the $1k AC leak in the car this spring is my major concern. I chalk it all up to this...It was cheep, and If I wanted to be THAT concerned with the sound, I would go all out and build speaker boxes. ANYTHING has to sound better then those 20 year old 4x10" speakers in the side walls! ;) -----Original Message----- From: Marc A.

Or if you want to be real high tech, you can order special acoustic board sold by many car audio vendors.. The board the speakers are mounted to have a incredible impact on the sound quality. -----Original Message----- From: Kevin Abato [mailto:delorean@xxxx] Sent: Wednesday, February 13, 2002 9:06 AM To: Dmcnews (E-mail) Subject: [DML] New Speaker Install...Save original car <SNIP> >> ...but the rear wall is too >> expensive buy another one to cut and mount speakers in.
