1. Which subs are not too expensive and make deep and dry bass. Don’t want a boom boom. 2. Have Canton RS 6 3-way with 2 25 cm bass. Can I install the bass in a case in the trunk and use as subs? Midrange driver in door and tweeter in front. Do I have amp with 2x 75 watts or 1X150 watts with soft for sub. 3. Which finished case fits into the Lupo trunk? Ideas? for 25s or 30s subs? 4. Do I need a rear speaker? Do I have a few Kenwood 16cm 3 ways? 5. How much do I need? Watt can handle my battery? Thank you & ciao your nickname Vatter
