About the Metra 70-6510 Amp Bypass Harness

Metra 70-6510

The Metra 70-6510 harness enables you to install a new car stereo in your Ram truck. It uses a "jumper" to bypass the factory Infinity amplifier, which means you don't have to run new speaker wire from your new radio to your car's speakers — this saves you a lot of time on the installation, so you can start enjoying your music sooner.

Since you didn't have to cut off your car's original radio connector, it's easier to put the factory radio back in when you sell your vehicle or return it at the end of the lease. Just plug the factory radio back in and keep the aftermarket stereo. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this harness is compatible with your vehicle. Warranty: 1 year.

Q
I have a 2004.5 dodge 2500 is this the harness I need? Will I need to replace the door speakers and will the dash speakers still work?
[ Devin  Jan 18, 2020 ]
1 answer
A
I purchased this same harness for the identical truck and it performed as advertised. My truck has the Infinity stereo factory upgrade and all of the speakers worked after the swap. The sound was much superior also. The installation was kind of a pain due to the limited space behind the dash on the passenger side, but it all worked out.
