So I installed this in the back of my transit EuroLiner: Headunit: Alpine 9894R BassPower levels: 2*Rockford Fosgate 1000bd Subwoofer:4* Alpine SWR 1221d in 55l BR each with 7cmPort 2 standard batteries +1 additional battery with 85 Ah and 3*1F Boa Powercaps plus 35mm cables at short distances. Lowpass stands on approx.70 Hz and Subsonic on approx. 30Hz So, the bass sucks loud(I burst almost the head), the roof and the side windows move visibly. Only I don’t really notice anything about the body or the clothes! That can’t be!!!!!!!!! I tried every music: Hardcore,Goa,Schranz, Techno,Hip Hop,low bass music,BlachMusic… Wodran is that please?
