Hey guys so I have had my system installed 4 years now. Just recently sound has been cutting in and out at a certain volume. If I have the radio playing above volume 38-40 it starts cutting out where everything goes silent than it comes back on. Higher I go with volume the more persistent the cutting out is. When I plug my iphone in the aux jack I can't go past volume 32-34 with the same thing occurring. If I keep the volumes low or below those levels everything runs fine.
I have a feeling I may need a new set of RCA cables, either that or it can be a battery wire or ground problem. Or possibly the headunit itself since it's an old radio (pioneer premier 8 years old). Any thoughts are welcome. Trying to get some insight before I tear the whole car apart. Also too the battery itself in the car is less than a year old.
Thanks in advance fellas
