Alright here's the run down, using mb quart high and mids with a dsc450 powering them, and for the headunit I am using a clarion with 5 volt pre outs. Now when my bass is hitting hard sometimes it sounds like the tone in the highs and mids change a little. It's only when the bass is turned up. Everything is tuned correctly checked with o-scope and adjusted properly. Now I checked on my dsc450 where the rcas go in, the rcas are a little wobbly, not the stalks just the ghetto rcas. Do you think when the bass is hitting it could wiggle one and change the tune?
Any ideas would be awesome and sorry for the horrible grammar and run on sentences lol.
