I am really new to this so please work with me. I have a M & K (Miller & Kreisel) MX-100 powered sub. This thing has two 12inch subs and used to rock!! The amp I think is acting up . If you turn knobs while its powered on it goes crazy and will not stop. I am wanting to replace the amp. I am looking at one at Parts express, but have not a clue on how to wire it up..I also will have to cut hole bigger for the amp. Any and all suggestions welcome..Thanks
