There are a lot of solid receivers out there that give you Apple CarPlay and Android Auto, built-in Bluetooth®, and SiriusXM connectivity. Very, very few, however, boast the shallow chassis of Alpine's iLX-W650 (only 2-13/16" deep), making it a great candidate for a smooth installation in many "problem vehicles."

If you are having trouble wiring your new aftermarket radio in your 3rd Generation Acura TL spanning years 2004 2005 2006 then this custom made wiring harness will help. We will create a harness for your exact radio installation allowing you to install the new radio without the need for any wire splicing or wire tapping. This harness will allow you to have a plug and play installation for your Acura TL with whatever compatible radio you chose.

The plug and play installation will allow you to retain your factory amplifier, speakers, subwoofer and navigation. You will lose the center speaker audio when installing an aftermarket radio.

We also add the AXSWC steering wheel control interface connector so you can retain your factory steering wheel controls if desired.
