Review on Axxess AX-ALOC648 4-Ch Adjustable Line Output Converter - 80W by Jeffrey Kue

This product was used with a Crutchfield aftermarket radio in my son's Grand Am. Due to On-Star GM wiring, a special Metra converter was required to keep the warning. This car has horns. This particular Metra converter came with a Crutchfield radio package. However, this adjustable line-level converter was also needed because the output of the GM On-Star converter supplied by Crutchfield was too high for the existing factory power amp that came with the car. This item was easy to install and required level adjustment. once installed it was easy to do. I recommend this product to anyone having a similar problem.
