Title: Don't use speaker inputs
Review: This item works great unless you try to use the speaker inputs instead of low-level inputs. It creates a constant buzzing sound through the speakers. Thankfully my amplifier came with high to low input converters. Once I plugged these in, there was no problem. Very adjustable to your car's speaker configuration.
