New 4 Channel Amp

ok so i have an autotek at1200 running my highs now and they get pretty loud but the sound quality *****. My dad has an old mtx amp in his suburban that he's willing to trade. It was made back in tha 90's but I dont have the series on hand. It was all black. Would this be a good trade or should i just wait and get a Infinity Kappa Four or something. I have pioneer premier components in doors and infinity coaxials in kicks all up front and infinity mids in rear.

bumppppp

uh buy my crossfire thats what you should do. very nice sq unit with .05 thd i heard from roger at crossfire
