Stereo Upgrade Q's
 

I have a 99 RAM 1500 Quad W/Infinity system (stock)

1) What size is my DIN hole? (1 1/2 or 2)
2) How do I bypass the Infinity amps?
3) Where do I run the wires for the amp and sub?

I just used a multimeter to shoot the stock wire harness to find my wires going to each speaker. I ran the sub wiring along the drivers side under the carpet to the back of the cab.

Im sure I have the same stock stereo unit in my 98, if not it will be close im sure. But, I took the head unit out to hook up some speaker wires for my high pass to low pass filter (for my amp) and on top of the unit it has the wire diagram laid out for ya. Tells you front, rear, right, and left speaker.
Also, i ran my power cable up thru the rubber gromit in the fire wall on driver side and down along the floor board. It went thrue very easily. The only problem i have is when i turn power off (key or power button) im getting a popping noise to the subs. I called around here locally and the guy said it was my remote wire. So, i moved it from the fuse panel (radio) and spliced into the ACC on the wire harness and it still does it.. Gonna try a few more things to see if i can fix it but if not, ill just take it somewhere to fix it.

i use a set of rca wires with the built in remote wire very nice feature.
