worked great

had no issues with product

Accurate description....perfect fit

This adapter was the exact one necessary to connect my OEM Bose system to my new Planet Audio receiver. My new unit uses the Bose amplifier and sounds great. With the new system, there is no need for an additional amplifier. Thanks for recommending this adapter and all of the great customer assistance. Sonic Electronix rocks.
