2005 Ram 3500 7 Speaker Infinity

Hello, I am new to the forums and have been searching for several days on various sites (including this one) to find a solution to my problem and am hoping you can help. I have a 2005 Dodge Ram 3500 Diesel Laramie. It has the factory RBQ (6 disc changer) radio and the 7 speaker Infinity sound. I am trying to put in the JVC KD-AVX1. I have read in some forums that all you need is harness kit with the amp turn-on lead and all is well to re-use the factory amp and others have said I have to bypass it. My amp is located behind the glove box. I am trying not to cut any wires in case I need to return to stock. What is the real answer to integrating my amp? Secondly, I only plan on using the amp that is built-in to the JVC unit and was wondering if I could use the front speaker leads on the JVC to power the 3 speakers located in the dash with a 500htz cap as well as the 2 front speakers in the doors. What are your thoughts? Any help would be greatly appreciated...

my experince with that car is you have to rewire the ampilfier behind the glove, a good way though is just disconnect the harness and use t-taps to each set of speaker wire.... test the main harness for ign. ground and 12volt constant...Thats SIK!!!!

Yeah. That is what I had was afraid of. Thanks!

you do not have to bypass the amp.  pac makes an interface that retains the factory amp, gives you 12volt and accessory wires. part# pacc2rchy.  available from any audio dealer.

  I would have to agree with autofx.  If there is a speaker in the center of your dash its probably a dedicated center channel created by the amp so youd lose that if you rewire, also i think... your front speakers are 6x9's or maybe they're 6-1/2's either way if you cross them over at 500hz you'll have no bass or midbass in your truck.
