Hi All, i own a pair of TBI Magellin subs that came with a pair of amps that have volume, crossover and phase controls and puts out about 160 watts and one of the amps quit working. Instead of buying a new TBI amp or having this one repaired by TBI, i was wondering if anyone knows of a sub amp that has these features that I could check out. Also I want to mention that I use the high level inputs where I just run a second set of speaker cables from my amp. Thanks, Tish
