well i know zapco is most likely better since i run zapco and all but i was wandering how the the sq quality on the jbl gti amps i was looking into a gti 6000 but i dont know how good they are sq wise compared to a zapco 9.0 of course the gti 6000 is alot louder but i can always get more 9.0s anyways plz feel free to comment about the gti series. and the comparision.
