ground loop isolator
I purchased 2 ground loop isolators to clear up my road noise 1 from a shop and one from radioshack. I tried running the isolator from RS between my crossover and my high amp but it did not help. The RS isolator had two male RCA plugs so w/o a coupler I can't run it between the deck and crossover. I got the 2nd isolator because it had female and male RCAs. I put this one in line between the deck and crossover and it cut out all my bass. The tech at the store told me it shouldn't that maybe it was lowering my input. So I ran a second rca from my deck to my high amp with the isolator on it and it got rid of the road noise but there is absolutley no bass coming from my highs now, w/o a crossover or filter just the isolator. It's probabaly cut off around 1000Hz.
My question is: Is it possible the isolator has cut out the bass and if so where can I get an isolator without the filter?
thanks for the help!
