Hello "Oh Wise Ones", I'm about to purchase 3 mtx 15's (here's their info). RMS Power: 300 Watts Max RMS Power: 300 Watts Maximum Power: 600 Watts Impedance: Dual 4 U Voice Coil: 2" Frequency Response: 19-150Hz Sealed Enclosure Net Volume: 1.75ft3 Speaker Displacement: .11ft3 Suggestions on amp or amps? Would like to run close, if not a little over rms. Have not completed the fb box. Have 9ft3 to work with so space isn't a prob. Suggestions on on placement/aiming? Going into 2003 f-150 scab. Rear fold-down seat removed, fbglass mold of floor and rear lower half of backrest. Will mount amp/amps behind backrest. Budget: 500.00 or LESS would be good. Thanks so much for your input. J
