hey guys i need some help on deciding what 4 channel amp to buy. i have a pioneer 4200ub deck it has 4volt rca outputs and i have 2 6x9 alpine r series in the front and 6.5 alpine r series in the back the rms is 100 watts for all four of them. so i would like some recomendations on an amp. i looked at a cadence xa175.4, a orion cobalt co6004, and a crunch gpv 1600.4. but would love some input on those amps and other amps that mite be better for my set up would like to stay under 200$ any info would be appreciated. thanks in advance
