I ordered a MB Quart q4.150 and it is on back order indefinitely so I need a good 4 channel amp to run active for ~200-230 shipped. 125-150w/channel. Old School and newer equipment, it doesn't matter, just let me know what you have.
that isnt an active ampWhy not just go with an ONX4.125? There HPF goes up to 13KHz
