I just installed my panasonic head unit and am putting the rockford fosgate FNQ3514 components in. They have a crossover that comes with them and it has one input and 2 outputs. (1 to the bass and 1 to the tweet) How do i make it so 2 channels can go into the 1 input so i can have the 2 channels RMS be 50 together instead of 25 and 25? Is this possible?

Most head units are not bridgeable. What model Panasonic do you have?

Don;t do it you will kill your speakers first and the your head unit,maybe if yourun the deck at - 12 and listen to non demanding music you could get away with two ohm stereo on the front channel that is if your cross over is bi ampable.

That is a nice head unit. It has Panasonic's MOSFET50 amp (25 watts RMS/50 watts peak X4.) The amp is 4-ohm stable and CANNOT be bridged. If you try to brideg the head unit, you will probably blow the amplifier output transistors and void your warranty.

The deck has 5V pre-outs for both main and sub. If the power is too low for you, I suggest you buy a nice amplifier.
