#12624, "RE: Head Unit Install w/o Infinity Amp" In response to In response to 9
You will have to run wires from the radio to the amp, not just jump the wires from one side of the amp to the other... there are no wires to jump. As far as using the 4" speakers in the knee area of the dash, make sure you hook up those speakers in series with the front door speakers so you don't blow up your nice new radio. Anything under 4 ohms will burn out the internal amplifier of a radio.
