This is a great product. Plug an play extra outputs to run to an amp. No cutting or wire crimps required. Definitely recommend if trying to keep stock head unit.

Quality Product at a Great Price!!!

May 17, 2009

My local car audio shop listed this same PAC AOEM for almost $70.00, so I jumped at the chance to purchase it for nearly HALF PRICE!!! First and foremost, this interface is extremely easy to install with simple hand tools, so it gets an A+ for that. I'm only running a 300 watt amp that pushes a single 12" woofer, so my system is pretty basic to begin with. Secondly the quality is unbeatable for the price...the wiring and connections are top-notch! Really the only flaw I can find with this product is its size...it's kind of a tight fit in the dash of my '01 Trans Am...but with a little finesse it can be tucked back behind the head unit nicely. Ive had the PAC AOEM installed for about 6 months now and have had no problems at all!

Excellent service!

December 1, 2009

I wanted to retain my stock radio, but desired a better sound that I know I could get by adding a sub woofer to my system. I ordered the PAC AOEM-GM21C adapter from Sonic Electronix to do the job. The delivery was fast and the product performed as stated. I was able to "plug & play" the adapter and in a matter of 15 minutes had my system ready for a sub woofer upgrade.
