So basically I have a 2001 Wrangler TJ that has a newly installed Sony MEX-XB120BT, powering minimum of 55Wx4. My dash speakers are Kick KS 5.25 speakers with an RMS of 75W. When I play them louder they keep making a pop during more bassy sections and even for some songs it makes my whole radio shut off. What's going on? Thanks for any information.
