Finally, work has seemed to slow down and I am planning on installing my
Rockford Fosgate 25 to Life Power 1000 in my 2006 Mustang GT in stages
over the weekend. The only problem I have run across thus far is that I
was planning on mounting the amp to one of the fold down rear seats.
Well, the amp is too big, so it looks like I am going to have to mount
it to BOTH rear seat backs.

I hope this sounds good because this will be the final complete system:

Alpine CDA-9885
Infinity Kappa 682s all around
A single Solobaric L5 in the Kicker enclosure wired for 2 ohms
The 5 Channel Power 1000
For now, I am retaining the Shaker 500 8" "subwoofers" in my doors.

I intend to tune the crossover points and gains by ear and I will use
the built-in 28 hz Subsonic Filter.

The only questions I have right now are

1. Should I pick 100 hz as my starting High/Low pass point or go lower
than that?

2. Besides difficulty in folding down the rear seats, do you see any
disadvantage to mounting the amp to both rear seat backs?

3. How long before I need Dynamat?
