Live with it,keep tuning,add another sub, get a smaller amp

[WadXpress]

I'm a hour from a store that I could by a sub at and then return it. The small local shop heard my truck helped me tune the 4ch but when we were doing the sub he just said the amp was a beast and the sub couldn't take it but they dont do any sundown. They have skar and kicker subs there

I don't know it def could be a faulty sub or something wonky going on but a lot of people have mentioned the same issue with the SA series subs in sealed applications.
I know Sundown will tell you they prefer the SA series to be in a ported application but sealed will work too. However I have read numerous times (I have never owned a SD sub) that those SA subs are Completely different animals in a ported enclosure

Bad noise usually is bad sub or bad (leaky) box.

To set gain - set your crossovers, make sure EQ is flat, any bass boost is at 0, and bass knob is at max.

I have 2 Sundown SA12 in a sealed box. each sub has 1.3 total cf then minus the sub displacement. They sound really good and hit really hard. I have them wired at 1 ohm and using a 1500D sundown amp. total of 1500watts, i have my xover around 80hz. If your having the problems of not enough volume or sound or sound crappy id say your sub is blown or a wiring mistake. I would go over and check all wiring on sub and on amp.

How about a dust cap that was loose and not sealed? Would that do it?

You definitely want that sealed

Yes.

Hopefully that's the problem. We will see tomorrow. Thanks for all the help. Hopefully this is the only issue

Its a sundown sub, not a JL W6. I would get a better sub made for your enclosure.

It was something as simple as a dust cap. Sounds great now. Thanks for the help everyone

I like to keep my slopes at 18dB +, especially with subwoofers. I don't want to have a low slope and have talk radio playing through my subwoofer when someone with a deep voice is talking.

It has more to do with the preout voltage I believe.

What?

Pre-out voltage only determines what level you set your gain at.

I swear I've read that somewhere before

I just watched some videos... I don't think I'm pushing it hard enough.. it's loud asf in person but these videos I'm looking at seem to really be going hard.

Gonna use a dmm later to set my gain. See if I can get it close to optimal. Right now it's around 50% with zero bass boost and flat EQ lpf ~80hZ
