The Metra CHTO-013 is designed to allow the user to replace the OEM radio with an aftermarket unit in select 2005-2009 Chrysler/Dodge/Jeep vehicles with the amplified sound system and will retain the use of the OEM amplifier. The amplifier receives a digital signal from the radio to turn on and off instead of the normal 12 volt analog signal in previous models. The CHTO-013 sends that digital signal to the amplifier to tell it to turn on and off. The CHTO-013 is packaged with both Chrysler CAN vehicle wiring harnesses to give the CHTO-013 a broader application range. Also the CHTO-013 is up datable by using the USB-CAB, the USB update cable, and the Axxess web site, to help eliminate inventory that is obsolete.

Harness Features:

  • Designed to be used with vehicles that have factory amplifier
  • Provides a 12V Switched wire
  • Provides mute, parking brake, VSS or speed sense, and a reverse output
  • 14 Pin harness with RCA's
  • Two 12 Pin harnesses to 22 Pin Chrysler harnesses
  • USB updatable with Axxess USB-CAB
  • Authorized Internet Dealer
  • 1-year Manufacturer's warranty

Axxess CHTO-013

January 17, 2015

Product came fast and was boxed good. So far my sound system is running fine, 2 12" NVX's 1000W running off a Sound Stream 2000.1 Tarantula Series. Lot of wires so be ready.

doesn't fit

February 28, 2012

This product was a good value if it worked. I had it proffessionaly installed in my 2006 Pt Cruiser GT which i even called customer service to make sure I received the right product for my vehicle. Once installed it never worked at all. DO NOT BUY THIS FOR THIS CAR 2006 PT CRUISER.

A must to keep OEM

July 4, 2015

This is a must have part if your just replacing the head unit on your ride but still want to keep om Amp. You really need to know what you are doing and what you have to do this on your own. If your a novice then I recommend someone who know electric wiring or a shop to wirer it up.

Works with original digital amplifier

February 12, 2017

this product really makes what it promises: makes an aftermarket radio to work with original digital amplifier. It doesn't promise to keep steering wheel controls to work, and they won't work with this kit.

will this work with a aswc-1 steering wheel harness?
laura s on Mar 14, 2015
Best Answer: yes as long as your car has the controls and your car takes this harness you should be good to go. I used this on my srt8 Chrysler 300c and works great

Best Answer: Hello Glen,

Neither is "best" or better than the other. In regards to Your vehicle, specifically, they are actually the exact same kit. The CHTO-013 is simply set up to work with a Broader range of vehicles, which has absolute NO bearing on Your application. We suggest the Axxess CHTO-01 , as its more specific, and doesn't include features that are not related to your vehicle.

i want to hook up an external amp an woofer to my factory jeep radio how does that work 05 jeep laraddo ?
A shopper on Dec 13, 2014
Best Answer: Hello,

First, your install will NOT have use for the Axxess CHTO-013. The Axxess CHTO-013 is meant to add an aftermarket headunit. What you seek is a LOC (Line Out Converter), like the AudioControl LC2i. Alternatively, you can consider the PAC C2A-CHY, but it has many compatibility requirements, so please make sure to read through the details - link below.

I have a Jeep GC 2006. It has a factory amp that is controlled from the factory radio. The factory radio appears to turn on and off the amp over the canbus as well as control the volume/ output level of the amp. Will this equipment be able to do the same thing? ( Therefore control the amp over the canbus.)
