Hi, So as I'm going to try and do a track day or two, I've decided to sell my in phase usw10 (under seat sub woofer). I could get it under the seat of the r26 recaro's - but you can't fully move them backwards, so I built an amp rack that sits inside the spare wheel - cannot be seem when carpet is down. The sub cost 140 and I spent 50 odd on the wood, screws, carpet. Will sell just the amp for 80 or both for 100 (but you'd have to collect it - I'm not posting it!) sub is only 3 months old. I can get pics if needed, Cheers, Wardyworld
