I would plan on spending around a thousand dollars if it were me. You need A New head unit door speakers and amps and crossovers for all of this also. I would go with 2 12s or 2 15s since you have plenty of room. You can get 2 12 inch solo baric L5s for $284.00 off of ebay a box for another 89.00 the rms is 750 on those speakers it will be plenty loud enough. Another 2 hundred for an amp. then you got a lil over 5 hundred for a head unit wire, door speakers and another small amp. Good luck
