Question about Car Audio & Video
I have two 12" PG Xenon subs wired at 2 ohms each. I have had my setup for over a year already and have not had problems until today. This morning I turned on my car and noticed that my subs were making a huming noise. I checked all of my wirirng and everything is fine. I turned off the car and I hear a loud thump from the subs. I tested my amp with new RCA's and the sound was still there. I noticed that the sound only comes when I hook up the RCA's to the amp. I have my RCA's seperate from the power cable and my ground is properly connected, so I know this is not the problem. I also noticed that when I turn up the volume I hardly hear any sound coming from the subs, The subs look like they are bumping, but the sound is very low. I tested each sub seprately and I get the sound from both. I don't the think there is anything wrong with the subs. I checked myre wiring on them and everything is properly connected. Can someone please help?
This sounds like a problem with the head unit output to the sub amp. Are you using a Pioneer head unit? If so, you may have a problem with some surface mounted fuses inside the radio on the main board. Certain Pioneer head units have a common problem with these fuses blowing. They are fuses for the ground on the RCA outputs.
Let me know if this is the case, and if it is I can give you the part number of these fuses and tell you where they are located, but you would need good soldering skills to replace them. Also let me know what model number your head unit is.
