ive got a set of jaycar kevlar 6.5" splilts as my front stage, and they work very nicely... extremely clear, and ive never had a problem with any distortion (unless i cranked it up so high that my ears started to hurt)... but even with the volume VERY loud, they were clear... im also running a 4x100 response amp. i think for its price, its a very good quality amp... go to the car audio australia forums and read up on response stuff - even people in the industry say its great stuff these days...
