Hooked up system in my sons truck last winter. Pioneer avg 4800bs head unit, JL 10" in sealed under seat truck box and 1200 watt boss amp. All stuff I had left over from other cars over the years. Worked and sounded great. Last week his sub stopped. I walked him through some troubleshooting over the phone. He replaced speaker wire and it was playing again. 4 days later it was out. All weekend and into tonight I have done everything I can think of to remedy. But now I'm at a loss... I ran new ground, power and trigger to the amp. I tried 2 different amps. I changed brand new rca cables. I took sub and box to anther car and hooked up to make sure it worked. I even bought a brand new head unit. All of the other speakers are powered by the head unit and work fine. Are the preamp hookups on the unit internally fused? Could they have failed and then caused the brand new unit to fail also?? I'm lost. Ugh.
