I have a rockford fosgate T400-4 and bought ID ctx 65cs comps for rear and ID x65 with Lanzar DCT 1-Inch Silk Dome tweeters. I x them over at about 60 hz and they were sounding really good. I finally pushed them on my way home from work on the highway. About 30 minutes worth of old school rap. Then all of a sudden my RF started going into protect mode. When I lowered the volume they started to play again. Before these speakers I had beyma 6.5" up front and O2 6.5" speakers in the rears that were 8 ohms with no issues. What is going on? I thought that ID were good speakers.
