I've never joined any forum, but have benefited from them in the past, so here's my first shot at this forum thing. Thought I'd add to all the help you've already received. I've got a 98 Dakota w/infinity. While I do plan a larger system in the future (thunderforms, components, dynamat,etc.), I got a freebie "junk" JVC from a buddy when we installed a new Alpine in his car. The "junk" deck had a couple wires screwed up from previous install, so figured I may as well use it after I repaired that. From help on this forum, I figured out I just needed to power up the factory amp, and I was good to go. I am using some Infinity two-ways I had laying around for the front doors, but just the factory in rear. The ONLY thing I did aside from a basic install was to run the remote lead from the deck to the factory amp. I left the factory tweets disconnected - Infinity's have plenty of high end. Granted, it's no competition system, and there is no bass (gotta wait for some $$$ for some subs), but considering I just swapped out the deck and front speakers, it's a pretty decent setup for my work truck (for now anyway).

 

jus so ya know the factory amp turn on is in the wiring harness behind the deck ull have to update us on ur progress!!
