My friend bought my ma auido eho154 and he has never used it, so its still brand new never been powered up, he dont have the funds to power the sub up, with the cost of amps and batts to put this sub to work he wants to get rid of it! The sub is 5000wrms/10000peak, quad 1.3ohm voice coils, 15", he is looking to trade it for two 12's in a ported box and he will throw some cash in to depending on whats offered for trades! Thanks
