Hey guys so I bought a new pioneer fh-x700bt head unit mainly for the fact that my old alpine unit didnt have hi/low filter settings. Anyways its installed perfectly, all of the wiring is good to go but my sub is not hitting.

I have 4 component speakers and 2 tweeters running to the head unit, and an amp running to the sub. In the back of the deck i made sure the proper wires are plugged into rear sw and the amp seems to be outputting/running and sound comes through everything else except for my sub.

this leads me to believe that the settings on the deck itself is not correct, my problem is I have no idea what settings they should be. Halp???

Yep they are all fine. All I did was switch head units but I checked all of the connections over again to make sure none came loose. Every wire is connected and in all the way. My sub was working literally with the old unit but as I switched everything except for the sub is working :/

ok so what you need to do is go into your sound setting on your head unit and make sure it recognizes there is a sub if it does and is still not working look at your amp and on the housing there should be little dials to turn if there is turn both all the way to the right and see if that produces sound. where are your grounding points?

The head unit has sub w: norm (there's a off, normal, reverse options). The only 2 dials on my amp are for hpf and LPf and those are maxed out. I really don't understand it being a problem from the connections but rather improper setup on the head unit? Like I said before the sub was working this morning on a cheaper different unit. Should I mess with the hpf lpf dials since my new deck has the ability to change those as well?

to add onto jbowles some amps will light up when there is power but the light indicator changes colors depending on the issue green always means good to go if it turns red it means there is an issue... what is the model of your amp and i can tell you what color that should be

I've always seen my amp light up green. Its a Sony xplode 500w. Right now I just replace both fuses but the amp doesn't seem to be turning on. I had the amp and sub professionally installed a while back but for some reason its not turning on now (no lights after new fuses)

ok where are your fuses? i hope one in the power cable and one on the amp right? if im right you need to A( make sure your grounded) B(make sure your not using too small of a fuse it should read anywhere between 25 and 50 on the fuse for your setup) check your power cable on the battery and make sure its not loose or corroded.. check your remote wire(blue) and make sure its screwed down tightly on your amp with a phillips screwdriver and make sure it is ran properly to your HU... the biggest issue at this point is power so in this order power cable to the battery and amp...make sure fuses are proper...check remote wire on amp and HU.
