great product

Would recomend this product as it makes installation much easier and cleaner.

Plug&Play, yes, really!

Bought CTHO-03 to fit a new Alpine dash am/fm/cd in place of the 2007 JK Wrangler factory radio. Worked from the first time, i just followed the wiring instructions that came with the CHTO-03. Balance, Fade work fine but the independent volume control for the factory subwoofer is lost now. General sound quality is same as the factory radio.

Great wire harness

Great harness to ease the installation of a after market h.u to a factory amp. Install took less than 15 minutes and was as easy as 1 2 3

Great product

I needed that box to change my OEM radio for an after market. Installed on a Jeep Grand Cherokee 2008 with Boston Acoustic audio system. Easy to plug, very convenient, and sound is very great.

Great value

Due to my vehicle (07 Dodge Nitro) which has a factory pre-amplified system, it did make wiring together a little difficult but, I took my time and read all instructions several times as i wired it together and I was successful in installing this correctly. The reason I gave a 3 star on the ease of use is only because of the above (pre-amplified vehicle) The instructions for none pre-amplified systems looked a whole lot easier! Please don't be discouraged by this review. This harness works well....
