How can I make my system louder?

[Skar'dSensless]

I am running dual Skar 15" EVL series 5000 Watt subs in a Skar factory ported box with a Skar SKVS 3500.1d monoblock amp in a 2015 Dodge Ram 1500 QuadCab. The system sounds pretty good as it is, but it just doesn't seem to be as loud as it should be. With a system this size I think I should be able to rattle the walls of building around me, but I'm only getting good sound maybe 10 feet from the truck. Would a sealed box make it any louder?

Because Skar...


I clicked on box info but nothing shows up. It looks way too small for two 15s from the pictures. Also did you upgrade your electrical? Anything over 1500ish rms needs some electrical upgrades. You have a volt meter installed?

Do you have pics of the system as it sits in there currently?
I'm assuming this is the enclosure...

Plus @ 1ohm id wager that Skv3500 is clamping 2k at best... Less if your electrical is subpar.

I upgraded to a Mechman alternator and added a XS D3400 battery. I took a screenshot of the box specs.

Yes, this is the box. It is currently sitting on its back with the subs firing up. And I did change to a Mechman alternator and added an XS D3400 battery

The evl subs are only 1250 watts rms. The dnr series is the 5000 watt line.

Running it through software, it appears that they are manufactured as sealed subs, optimally. 3.5 cubes sealed according to my software. 6.5 cubes ported, which is a fairly large box for a 15. Not very efficient subs on the box size.
