Hey Folks, I just wanted to share my Sound Quality Upgrades on my 07 Corolla.
I have had a basic 2 way passive front setup using Polk Db6502s for a few years with a nice JL 12 w6 sub in the trunk. I came across a great price on a used Audison Bit One and went for it to build a 3 way active front setup. You can see my equipment and system design in the image below.
Initial install of the 6.5 woofer and 1 in tweeter in the sail panel.
Sound deadening with 80 mil Noico on the drivers door and plastic interior panel. I also deadened the passenger door, trunk, and beneath the rear seat. I still intend to do the floor under driver and passenger feet and ceiling panels as well. I was amazed at the difference to reduced rear tire noise after doing the rear seat!
I've completed all the work on the install. I'm just digging out my pictures and documenting the work to share with you. More posts and pics to come. (-;
