Think I've replied to a similar post in the past, but here goes....
I've always been into cars, even from a very early age, and part of that (when you're in your teens/20s anyway) was having nice I.C.E. I started reading some Car Hi-Fi mags, and read 'Max Power' before I could even drive, but they were purile and childish, and left me a bit cold after a few years, in spite, or maybe because of, the ever increasing amount of bare flesh on display. (Whatever happened to Olivia Stringer?)
As I got older, I started to lose interest in I.C.E, and shifted my focus to I.H.E (In Home Entertainment), I started reading WHF in around 2000, before buying my first 'proper' system in '02.
This was further compounded by having my amp, CD changer and subs nicked out of my car a couple of years ago..... I haven't bothered replacing them, I just use the head unit (an Alpine..... Some habits just won't die) and the speakers in each of the doors (JL Audio 5x7s).
I think the only way I'd ever get into I.C.E again was if I was able to buy a nice classic or American car, which would be used solely for pleasure.
I don't mind (damned with faint praise? I don't mean to, I'm very happy.) the switch to home entertainment, we watched 'Knowing' last night (really enjoyed it too, despite the reviews) and the sound when the plane crashes is mind-blowing!! Makes the expense and hassle worth it, 10 fold!!
