i need some advice on selecting amplifiers for four brahma 15 inch woofers. my selection so far is zapco studios, two rockford 3000t, 2 kicker 2500, 2 orion 2500, 2 hifionics 2400, or 2 arc audio. does any one know if us amps, or mtx would be good choices? they are going in the back of a 2000 yukon in a seald fiberglass enclosure. any one out there can maybe point me in a good direction for good amps.
