pioneer ftmfw, i got the older premire 860 n i love it, has so many features, and 6.5v preouts, i love this thing, mine ran like $600 n i got mine for $250 so i got one hell of a deal, and they play so clean to, gains for fronts, gains for rears(on headunit) 3 db slopes for each output, n xover freq's 50-200htz on all outputs, and can be switched over to pro mode n run high, mid, low from the front, rear, sub outputs, or be ran regular with fullrage front n rear, n low subs, well worth the buy imo
