so have my headunit, went the alpine ida-x305s, gonna run a LLC to use the ICC as a aux input but also lookin at a 5 channel amp with full speakers and a sub down the track but for now was thinkin about how to hook up the factory speakers to the headunit. was considering running new cable from the HU to the speakers and retain the factory wiring from the ICC but thought it may have noise.due to both using the same speakers.. any thoughts??
