Ok guys I really need help selecting an amp to work with my Magnum S-9. I've saved up my money and just want to make sure I'm spending it wisely. My radio swings 50 watts pep on my Dosy meter. Fatboy amps recommends I use a 1 2879 x 4 2879 High Drive. Xforce amps recommends a 1 2290 x 4 2879 and to keep my deadkey and mic gain turned down. Most people on other forums is recommending a straight 4 2879 High Drive. I want something that is going to produce the most clean output power for my money that I can use everyday and be reliable.
