Stereo upgrade...
Greetings all,
Just signed up and am new to this forum. I've read some threads pertaining to the Infinity Stereo systems on Dodge trucks. Not sure if I'm doing this correctly or not but here goes.
I have 2004 Dodge 2500 Crew Cab with the 5.9 Cummins. I notice it has the Infinity system, which reading other threads has 7 speakers total. Over the years I've accumulated a few Alpine CDE 175BT stereos (I like them) and was wondering (in an attempt to save money) if I could install this head unit and another Amp simply to power a sub I'd like to also install? Have read that this Infinity system already has an Amp which I'd like to continue powering the 7 factory speakers. My thinking is that I could use the HPF/LPF features of the head unit to reduce whats needed to increase mids and highs of the factory speakers and use the second amp to power only the sub? Is this a plausible idea or simply wishful thinking?
Eager for any feedback but especially of that which agrees with my line of thinking. 😉

I'm not sure I follow your idea correctly.
The factory infinity system is all in line, your 4 speaker outs feed directly to the infinity amp and it distributes accordingly to the speakers. I'm no audio head but in my opinion the infinity gets more crap then deserved, I've been very happy with any truck I've had with it all the way back to my 96. It's there, its wired, power the amp and go. Most if not all aftermarket stereos I've encounter have RCA out for a sub, so you should easily be able to used that for your sub hookup?

If you have all the components you need and just want to get the wiring right, companies like Metra, Crutchfield, or Sonic Electronix will be able to get you what you need. They also have tech support to help during install.
I've had great results adding a sub using a Kicker stereo line output converter. This is an easy way to add a sub. I've upgraded several auto stereos using sub jacks on back of head units as well as speaker level inputs, and can't tell the difference in sound.
You've probably seen the custom sub boxes that fit under the Ram rear seat(s). I got one on craigslist for $50 and it has worked very well.
