Y connector cables
Crutchfield Customer Review (What's this?)
I purchased 3 of these since I only had a single set of pre-outs on my integrated amp. I needed to run one set to my amp, and another set to my powered sub, the 3rd set I installed in reverse since there was only one rca connection on it. Good quality connectors with gold-plating; affordable compared to other options, better quality as well. Fast shipping. Thanks, Crutchfield!
Pros: Quality and price
