The Tuscan is a small SUV that can get loud easy I've seen 4 type r 12's on a 5k break 150 then do demos for half an hour. A moderate pair of 15's with a 3.5k-5k will get you very close to 150. Spend the money and have a good custom box built. Get a solid alt from a good company and a pair of cheap agm group 31 batteries with 50ft of 1/0 and you will be fine
