I currently have 2 12" Alpine type R's wired to an Alpine MRD-M500, ive decided that they are not loud enough, I was wondering if anyone here had a suggestion on a new set up thats going to be much louder, clearer and just blow me away. I have a 2003 ford explorer sport, thats 2 door, and im looking to spend around $1100 on the subs and amp, im open to all suggestions. thanks for your time.
