[QUOTE="Fresh40, post: 8592077, member: 673598"] So I'm stumped... getting a lud hum from the subs. Doesn't matter the source or volume or playing anything. When the sub amp turns on the subs make the noice and it is a constant tone. This is not a new install. Its been in this car for 4 years roughly. It comes and goes for the past 2 weeks. I checked the ground as that what my first thought of the cause. But the ground is solid. All connections to the sub are secure. Not getting any humming sounds from the highs or their amp, just the subs. Not sure if I should open up the dash and check connections or test something else.... The following is what I have.... 2006 Acura TL w/ nav Phoenix gold amps O.5 sub amp ZX450 4 channel amp 3 - 15W6 JL Audio MB Quart 6.5 components x2 Using 2 line out converters connected after factory car amp. I've owned all of this for 20+ years and never had a problem. [/QUOTE]
