I was wondering if anyone has some favorites. It is going under the rear seat of my f150, I have finsihed the box and will be installing in the morning. Currently I have bought the JL 10W1, Kenwood shallow mount, Boston G1 and the Power Acoustik STW shallow series. Iam going to try each sub tomorrow and see which sounds the best. I have .6 airspace which is just about right for these 4 subs. Let me know your expirences. I will post pictures of the new install tomorrow when it is done. Oh ya, I will be running these with a Boston GT 22.
