So, to begin, I'll list what I'm running for my system.
Vehicle: 2002 Subaru Impreza Wagon (this is somewhat immaterial because I'm not using any of the original sound system, door speakers, amp and all)
Head Unit: JVC KD-R520
Speaker Amp: Rockford Fosgate R250X4 Prime 4-Channel
Sub Amp: DB Drive OKUR A4 2400D
Subs: x2 Sundown Audio SA-10
I've been running this system for quite some time now in my Impreza. For the last few months I've been trying to figure out exactly what's going on within my system. Out of the blue, I started receiving this very dull tone from the subs. I could usually run the volume around 40-46 and it sounded amazing. Now, its like its been cut in half, and there is also some sort of distortion/interference coming through. This happens intermittently and sometimes will stay away for a few hours but then it happens again. The system seems to operate as normal as soon as the car is started, but eventually loses its wonderful bump. It sounds like with every note that plays, there's an extra sort of unwanted vibrating sound, or like a buzzing sound. I have sorted through all of my connections, found nothing. I replaced the RCA's, that still did nothing, checked my battery voltage and voltage drop, still nothing. I'm curious as to whether or not this could be a grounding issue? The DB Amp is grounded to the floorboard under my back seats. The paint is ground off and it does make solid connection, but is it worth my time to replace that with a full on returning negative cable to ground to the battery? I know for sure that both subs are perfectly fine, because the issue comes intermittently. I was curious as to whether it was an amp issue, but I'm not fully certain, hence why I'm here asking questions. If anybody has any input please do let me know. I really want to get this system going again!
