Something seriously wrong with my install/box/amps? pics n vids

[WOT]

Had my stereo hooked up for a little while now, figured they might need to be broken in or time to unstiffen, but I think ive got a good problem with my subs/box or amps.

Im running 2 audioque sdc 2.5 15's, and 2 cadence txa 1000D's. Each amp is running one sub @ 2ohm (650rms)

Its a common chamber box, t shape (beauty panel on top hides that) with a dual port with a 38hz tune.

I personally think it hits pretty hard, makes ur nose itch and the mirrors go crazy and what not. But I dont think its even close to as loud as what some people are running with the same stuff or equivalent. Ive never HEARD louder though, but nothing is in my area. Whne your in the car obviously you can feel the bass, but you cannot feel it if you walk like 5 feet from the car with the doors all shut, just hear the comotion inside lol

Take a look at this vid showing how much the subs move, they barely move, maybe 3/8" total. Some people seem to move over an inch....

So then I thought ok maybe one amp isnt even working. And the way I have my rcas run is from the HU to the top amps INPUT rca's, and then from that amps OUTPUT rcas to the bottom amps INPUT.

So when I disconnect the top amps OUTPUT (meaning the bottom amp isnt getting an rca signal) the subs move MORE, they definetely were wanging in and out noticeable more as I could watching the path the sub stitching took, plug it back in, stopped moving as much. BUT, when I disconnected the rca's like that, they didnt have as much output..... weird?

Heres a vid of the hatch of the car for reference. Thats with 3 layers of sound deadning and the latch as tight as I can get it. Moves alot, but its really not all that loud inside the car.

Im having a tough time deciding what to do. I originally wanted to buy 2 more subs and make a wall because I wasnt happy with the output. Now I may just rebuild a box thats more basic with just a single slot port. Or there may be trouble with my amps I dont know I need some help with this one

thanks guys

out of phase perhaps

audioque reccomends like 4.5 cuft per 15, IDK if your box is big enough. I suppose you could always add more power too.

DJ said my 8 cubes NET was perfectly fine and what was recomended by him. And Im doing the full recomended rms wattage already.....

what sorta battery have you got?

You can't really go by how much the subs are moving... especially if you're playing close to tuning. Play something that sweeps down from your x-over frq down to tuning and watch the difference in cone movement as it sweeps...

big oem, 110amp factory alot, 0 gauge wiring to a dist block, then 4 gauge to the amps

sounds like everything is fine. might want to make sure the ssf is set low enough

ssf?

I have my subs crossed @ 63hz, with a -6db slope and the loudness function was ON during that test.....

subsonic filter

ya that was set perfect and hasnt been touched. Im curious is my port placement could have any effect.

I dont get why the subs start wanging more when the one amps outputs are removed though..

must be some kind of wiring problem, I would assume that you have one woofer out of phase and its fighting itself... other than that, it could be that you have a defective amp or maybe a pinched/nicked/etc wire....

stranger things have happened

maybe... imp. rise ?

port looks kinda close to the hatch

If that the case ill bet my left nut one of the subs is hitting out of phase. Go switch the pos and neg speaker wires on just one of the amps and see if that solves your problem.
