i used all old school stuff, the crossover is a ppi frx456 elctronic xrossver, and a ppi deq230. don't get me wrong i wasn't putting mtx amps downs, but i just have a hard time to set it the way i like it. and orion amp is almost plug and plug, and mainly due to the high thd rate, you do have to consider the mtx amp is .2% thd and the orion is 0.03 and thats a ton of difference in the clean watts you are delivering to the sub. so you wouldn't you agree thats one of the major factors why one amp costs alot more than another, quality?
sorry '99golfer i wasn't trying to start a thread.
