Issue with subs

[ImEnNergy]

Can anyone help me out, I have a sundown sa-12 in the middle, two nvx vcw124's on the sides, on a hifonics x2200.1d. When i turn the volume up on my headunit, or my bassknob it starts to sounds like an extremely fast heartbeat. Doesn't seem to cut out, The gain isn't even half way up, they are being pretty underpowered as it is. also are brand new, My headunit is a pioneer FX-x700BT. I'll post a video on youtube and link it, watch towards the end.

Well, I'm no professional....

BUT if you can't get your amp tuned properly... Turn your gain to 1/4, check your settings on your deck ("bass boost" and the like at 0), and how's your voltage when it does that?

When I first got my old setup put in my truck, it was doing something very similar because everything was out of whack (including only being able to go to 7 on the volume of the deck (35 being max) before it was excessively loud)

Also whenever my bass would hit (and do the same thing) the other speakers would flutter the same way.

Check it out (if you have already, check again) and get back!

How is it wired>? It sounds like there is potentially a lot of issues here

bad ground among other things. do me a favor, turn your system to volume 1 and shut all your doors. walk around and with out hurting your car bump into your car. if nothing happenes open and shut each door hard. if you hear the sub thump it's a bad ground, gain to high, bad rc connection.

is the SA-12 wired with the NVXs?

[ImEnNergy]

It is all wired down to 2 ohms, the sundown is wired the same/with the nvxs, and I will be checking the ground in a little bit, I've Never had a problem with the ground before this I had the sundown and two kicker comps in it.

ok I'll ask. How do you have it wired to 2 ohms?

[ImEnNergy]

Each sub wired positive to positive, negative to negative, then positive to negative going to the amp.

You have two D4 subs, unless I'm missing something. You're not wired to 2 ohms. Measure it with an ohmmeter.

Edit: Just seen the SA-12. Dafuq's going on here?
