My Car Audio System
When I was young, more bass = better. When I got older, I wanted a clean sounding well balanced system where every note sounds equal to each other and the details come in nice and clear. This is what I have done to achieve that.

TermLab reading of the IDMAX sub with music.
My previous PWK box using Polk MM 8's but I replaced it when I burned both subs from playing too hard. They sound very very good and pounds hard.

01 Feb 2017:
Had these for a while now and the TC90TD foam surrounds are starting to deteriorate so time to bring out the spares to try them out.
These are the newer TD5 version which uses a shiny titanium inverted dome. Back magnet is also shielded.
Need some break in before it sounds better.
