Another vote for Visual Ice here, this is my Alpine SWR-1242 in one of his boxes....
Sounds epic being run by my Genesis amp...
It's got a remote for the sub channel on the amp which is nice and handy, managed to squeeze it into a blanking plug in the centre console here.....
Makes adjusting the bass very easy, and I can turn it right down when "She Who Must Be Obeyed" is in the car.
Lastly my head unit, I looked at the Erinson or whatever they are, but just didn't want to risk it. So splashed the cash on this Alpine INE-W928. Absolutely fabulous unit, works with the SWC and the display in the clocks, so all good.
Just got to get my tweeters in the A pillars and I'm done, Oh did I mention I'll be 55 next birthday, never too old for good sounds
