its an old xtc amp.... coudnt find any details on it but xtc as a good brand is somewhat questionable..... Plus they dont mention any of the details on any of their products even on the official site. eg, rms values of subs, thd/sn ratios of their amps etc and that is not a good sign.
some subs had made there way into peshawar about a year ago and on of the shop owners told me i had wasted money on an alpine type R 15" and that i should have gone for a 15" 3000watt XTC sub he had.... unfortunately he didnt say a word after we demoed both subs...
point is, dont waste ur money on this amp. sell it to some shop keeper and grab a branded 4-channel amp.
