i have a magnum s6 175 in my pickup that i would like to put an amplifier behind. i want to go pretty big...say 600-800 watt dead key and around 13-1500+pep. i dont want to deal with puttin a motor maul in my truck, but i already have a 200 amp alternator i put on it. the magnum dead keys at 1 and swings to 125 pep on low, and on high dead keys 10 and swings to 200 watts pep. is there an amplifier out there that can handle this kind of wattage and swing? what other options do i have if i want to add more power but not change radios. also, i have been looking at a ranger 63ffc4 which dead keys 200 and swings to 400 watts pep. is there an amplifier out there that will handle that? thanks.
