That sounds like a decent setup, what exactly is the problem?
If you are looking to add two more subs, I would HIGHLY recommend using the same model that you currently have.

AMPS:
XS-1500.1 Class-D Mono Block with Dual 2 Awg. Power & Ground Terminals
450 Watts X 1 Channel @ 4 Ohms
900 Watts X 1 Channel @ 2 Ohms
1500 Watts X 1 Channel @ 1 Ohm
SUBS:
PSW812
12” ALPHA 800 SERIES SUBWOOFER
Proprietary Cast Aluminum Alloy Machine Cut “Alpha” Basket
Proprietary Cooling Rings for Motor Assembly (Patent Pending)
Kevlar® Reinforced Composite Balanced & Laminated Cone
High Tensile Strength Two-Layer Surround for Enhanced Control
Flat Progressive Rate Nomex® Damper w/ Spiral-Woven Leads
135 oz. Double Stack Magnet
Rated at 900 Watts RMS
92dB Efficiency
Frequency Response of 28Hz to 500Hz
Dual 2 ohm 2 1/2” Voice Coils
8-Gauge Sure-Lok Input and Output Terminals (Patent Pending)
Mounting Dimensions — Depth: 168mm / 6 5/8”Through Hole: 275mm / 10 7/8” Diameter: 312mm / 12 5/16
I cannot find ported enclosure specs on this sub. The web site has sealed or BP designs in production... but no ported designs.
You may be experiencing over load of watts to each sub when you really crank it up. In a ported box, it takes much less power to reach X-max (maximum excursion limits) on a sub. The subs are rated at 900 watts RMS each, so in a ported enclosure, you may hit X-max at 750 watts per sub.
Say more please...
