Didn't think guessing where 80 hz was was to hard lol

Do you have a DMM OP? and agreed ^^^^ Its not that hard... lol
Does using some bass boost on the crossover harmful for the sub and/or amp?
Phase for sure
okay guys I have everything tuned right like y'all said and I used a dmm to check the voltage from the power wire to ground wire and it reads a little more than 12. while the truck is not running. Still hardly no bass coming out of the sub just a little tiny bit. Should I drill a hole through the bottom of the cab and ground straight to the frame? I am out of options and getting really frustrated because it seems to me like everything is right. I also don't get how to fix a phasing problem I see the phase knob on the amp but what to do with it? Thanks for all the help up to this point.
What is phase, or what is it for?
I don't know what kind amp do you have but i have a hifonics brz 1700 powering a single 12 dual 4 OA v.2 ported to 32 hz and to get that thing moving i had to turned the bass boost level to 9:00 and gain to 4:00.
Grob. Unhooking one sub see what happens. Phasing issues because of wiring will take 5 Minutes to fix. Unplug on and if it gets louder then one is wired wrong.
unhook the sub wires going into the amp...grab a 9v battery. Touch pos-pos and neg-neg with the speaker wires and battery. If both subs move the same way, they're in phase. If not, out of phase
A ground issue isn't really going to cause a decrease in volume. At least for me it didn't, just gave me ****** voltage
I have attached pictures of the settings on my amp and a picture of my current ground. As far as checking the phase, when i read the ohms on the wires going into the speaker terminals on the amp it reads 2 ohms. I have them wired together using this wiring diagram.

There have been 5 or so post about phase. Check it out and rule it out. Its the fastest and easiest thing You can do. Unhooking the second speaker. If its a phase problem, unhooking the second speaker will make just the one still playing 5 times as loud as both playing.
