My 2008 dodge ram has the Infinity system too. I bought the truck new and just replaced the factory radio last year and had to juggle the idea of keeping all seven speakers vs. Going to only 4 speaker run off thr radio. So glad I kept the factory amp.
I did the Metra interface too. I have not added any subs yet in the truck. I like my under the back seat storage space too much. The Infinity system in my truck is designed to use the 6x9 in the driver side door as the subwoofer. Its not a bad system but, the speaker wears outs pretty quick.I did replace the head unit in my Spyder GT and used the Metra adapter to wire to the Infinity amp. Then I added a second amp to run the sub in the trunk… Sound is awesome.
Okay, I will check that out! Thanks@Rodger3G ..... have a look at this post...read to the bottom and you will find my set up...You may have to scroll up a bit?
Looking for suggestions to upgrade the speakers only in my factory installed infinity system. I understand they need to be low ohm (2-4 ohm?) to match the amp. Also does anyone know the model numbers of the speakers in this infinity system (front door, tweeters, center, rear panel) for...www.club3g.com
