I installed a d3 on my 03 aviator. it looks factory , I love it.
I have a factory amplified system, with an amplified sub, when I turn my vehicle on, the sub makes a thump sound. But after that it sound great. I bought the d3. the dash kit, and the harness with the rca's for the sub from Best buy. do you guys know what can I do to get rid of the thump?
Thanks for the help.
