I got a 10in. Rockford HE2 in my tour, i bought mine brand new on ebay for $100. They are 400wRMS 800wMAX. I bought a 4x8 sheet of 3/4 MDF and built a custom box. I got a 1800w kenwood amp for $230.00 from millionbuy.com and this system sound awesome. Im thinkin of putting another 10 in to bump even more.
