Skullz Posted December 22, 2016 Report Posted December 22, 2016 Try bench testing everything if your able to do that to see if you can isolate the problem to a specific piece and rule out the car or wiring, and if not you'll know you have an issue inside somewhere you need to track down. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2
ShadeTreeMechanic Posted December 22, 2016 Report Posted December 22, 2016 I use an EQ with a built in pre amp to drive the line. This allows me to keep the gains really low on my amps. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
reedal Posted December 22, 2016 Report Posted December 22, 2016 you could try grounding the amps to a closer chassis/frame grounding point, but I'm not so sure that would eliminate the noise. It's possible, but a direct ground to battery should be fine the way you have it. Did you double check to see if the noise is still there with the RCAs not connected to the amp, like you said you would?

ShadeTreeMechanic Posted December 22, 2016 Report Posted December 22, 2016 Turn your gain down. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
CarbonCone Posted December 22, 2016 Author Report Posted December 22, 2016 Turn your gain down. Still does it while turned all the way down. When I flick the amp to LPF I get a really high pitch noise, on Full and HPF it drops to a hissing noise changing the eq doesn't change a thing. Gain changes the hissing volume but still able to hear it while gain is all the way down.
ShadeTreeMechanic Posted December 22, 2016 Report Posted December 22, 2016 Does it do it with the car engine off or only when running? 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
