Well that HU has 3 sets of rcas,and using one 4ch amp? and you are, or have bridged ch 1/2, or 3/4? So you will need the short rca to go from the HU to the eq subwoofer to the eq ,out of the eq, you run the rcas from the sub outlet to the inlet on your bridged channell of the amp/whichever 3/&4, or 1&/2, and switch the selectors to bridged/mono,and or the HPF to LPF on those two bridged channels, and set your gains accordingly after all hooked up,along with the mid/highs.From the HU I would run a set short of rcas from theHU front tothe eq front then a set of rca to the amplifier to the inlet of the channells that you have the front /rear speakers hooked up to 1and 2,or 3 and 4, and be sure that the selector switch for this one is on HPF/STEREO.and set your gains accordingly.If you are running components, hopefully you are, then the cross-overs will be needed for the tweeters,.Just sounds like you ran the rcas wrong by the way you have explained, and didnt switch the selectors properly, and may also have plugged the wrong rcas to the wrong ch on the amp also.Take your time, and make sure you run the rcas to the right ch, and that way you will be able to switch the HPF to LPF for the subwoofer on whichever 2channels you bridged, and check the switch for the HPF on the two channells you have for the mids, and highs.This is the way i would install an eq with a 4ch bridged on 2 channels .It is recommended to hook everything up before turning on the amplifier.Aslso, make sure that the amplifier will be able to handle the Ohms load of the sub installing.Most common amps will handle 2ohms bridged, but usually 4ohms,unless specified,so be sure that you have your sub impedance, along with wiring it up for the proper ohms load for the bridged ch of the amplifier before powering it up.:banghead:After said and done, set your HU LPF, and LPF to your liking, as everyone hears differently.Hope this has, and will help.I think it will work just fine,

i only have 1 sub output on my HU. so im stuck thanks for all your insight so far. i need a diagram or something ahhhhh

Have you tried to use the RESET button on the HU yet?That may work also?Worth a shot.What HU is the # on the face say?

Hey, I was checking out the manuel, fairly quickly, and on pg 23 it says that with the POWER IC On that the speakers are driven by the built in amplifier, and with the POWER IC OFF no sound is produced by the system?Try that out?

Also just at the bottom of the pg 22, about the addition of adding an external amplifier, and what to do with the Power IC
