So I have a PYLE 240W 2 CHANNEL AMP, speaker impedance of 4-8 OHMS ,frequency response 20Hz- 30KHz, output power 70w x 2 RMS / 120W X 2 Maximum.. what kinda speaker should i get that will be the loudest and clearest. This is a special project.. I am actually putting this on my ATV.. yeah I know pretty redneck but what ever.. you gotta admit it would awesome riding through the woods blaring some AC/DC or some Pantera.. anyways.. some one please help and I like to keep the speakers from being super expensive
