former targa user here. i had my x652c seps and 10" dvc4 sub powered by a fenton 4100 amp (later changed to v12 1507) ok naman ang targa in terms of performance. bang for the buck talaga. kaya magtunog high end if tuned right.

my current set up is ryan audio kevlar seps and jbl gto 12" sub powered by ryan audio Q80 amp. (budget meal pa din) it really depends sa tuning para makuha mo gusto mong tunog.
