like the title says. i need 4 matching subs. 15's. preferably d2 but d4 will work too... They dont need to handle lots of power. in fact. somthing between 300-600 wrms per sub will do fine... i was going to do 8 12" hifonics hfi's walled but i cant get a wall big enough in my car to fit all 8..... dont want to spend over $400. i know its cheap but its a budget system... lmk what you can come up with
