Hello everyone, Im new to the forum and car audio. I have run into my first problem. I have a 2012 Lx Sedan with a 4 speaker system. I upgraded the stock speakers to Rockford Fosgate R165x3 6.5 speakers first, before recently upgrading the head unit to a Sony Mex-Gs610Bt. The HU has 5V preamp outs which i am not running into an amp, I'm getting the speaker signals from the harness off the HU. The problem is this; I was playing a particularly bass heavy song when the audio cut out. I checked the USB connection to my phone, it was fine. I switched to an AUX cable, nothing still. I switched to the radio tuner on the HU which was still powered and still no sound. After restarting my car I heard a faint popping from the speakers but still no audio coming from them. I removed the HU to check the crimp connections of the harness and they were all solid. Does anyone know of any possible causes of the problem? Is there any other stock amps or crossovers between the HU and the speakers that could be blown? Possibly the speakers are blown? I will try playing the stock HU and seeing if that works.
