Taylor Campbell Posted January 7, 2014 Report Posted January 7, 2014 Hey everybody. I have recently installed a clarion XC1410 4 channel amp in my dash right below my kenwood excelon. Kenwood and 4 channel are on the same ground. Before the install I was using the kenwood's internal amp to drive my speakers. The first time I hooked up the amp I had white noise and alt whine. I ditched my cheap unshielded RCA and bought some Monster XLN's and lost the whine. I have traced the alt whine to the radio antenna. 0 whine on the radio with the antenna disconnected. Faint whine noticeable when music isn't playing with it connected. Am I getting a ground loop through the radio antenna? Is there anything I can do to prevent this? Vehicle is a Toyota Camry . thanks for the help.

Brian617 Posted January 8, 2014 Report Posted January 8, 2014 I have a similar issue. Did you ground the radio chassis, or just use the antenna ground? I'm wondering if I shouldn't just use the antenna ground since I'm only using RCAs and the head unit doesn't require much current.
Taylor Campbell Posted January 8, 2014 Author Report Posted January 8, 2014 I grounded the chassis. I have a mini four channel amp in my dash and I don't want to ground both through the antenna. And does any one have any experience with those antenna filters?
mothra Posted January 8, 2014 Report Posted January 8, 2014 i install those mini 4 channels all the time, I only use the same power and grounds for the Alpine units. For the Clarions I use separate power and grounds usually a 10 gauge size. The first couple I did had the same issue you're experiencing but when I change wiring and grounded to a different location the noise went away. I don't know if this will help you but it helped me. First i'd try grounding in a different location than go from there. if nothing changes, nothing changes You don't know what you don't know, till you don't know

(my clarion replaced a factory amp) But I will definitely try this out!
