i have a geo tracker and i have 2 GNX 12's (4-ohm single voice coil) in a bandpass box, right now i have a kenwood 728s (300 watts by 1 at 4 ohm) i went to different places and they said it wouldn't make much of a difference if i bought a different amp, i would like to know what do you recommend? i would appreciate any help i can get. and is there anywhere around west tennessee that i can buy the mm124's? i used your dealer locater but it said there wasn't. thanks again for any help.
