Was running two Alphasonik PSW812J in fiberglass pocket enclosures powered by an Alphasonik PMA1000DA amp in my Dodge Magnum. Just blew one of the subs and they don't make them anymore meaning I have to buy two subs (RATS!). Given my amp specs (below) and fiberglass enclosures with limited airspace, what subs would you recommend for my broke a....?

AMP SPECS
1000 watts x 1 @ 4 ohm mono
1500 Watts x 1 @ 2 ohms Mono
2060 Watts x 1 @ 1 ohms Mono
Variable Low-Pass Filter: 50Hz - 150Hz @ 24dB/Octave
Variable Subsonic Filter: 15Hz - 40Hz @ 24dB/Octave
Variable Bass Boost @ 45Hz: 0 - +18dB
Variable Phase Shift: 0 - 180i½
THD: <0.08%
Signal-to-Noise Ratio: >100dB
Frequency Response: 5Hz - 250Hz
Input Impedance: 10kO
Input Sensitivity: 300mV~8V
Tiffany-Style RCA Jacks
Parallel Line-Out RCA Jacks
MOSFET High-Speed Switching Power Supply
Heavy 4 oz. Pure Copper PC Traces at All Preamp & Amplification Stages
Internally Mounted Fan-Cooled Power Supply
Solid Brass Nickel-Plated Terminal Blocks (4-Gauge Power, 8-Gauge Speaker)
4-Way Protection Circuitry: Thermal, Short Circuit, Overload & DC Offset

You will need 2 subs that are Dual 4 ohm and around 1000watts Rms (given that this amp is really a 2000 watt amp).

Post your budget and the list will begin.


Also do you have electrical upgrades? IF not you may want to think about running the amp at 4ohms(1000watts rms) so that you have proper power to the amp.

No electrical upgrades, just a cap(which I recently read don't do jack). Thinking about doing the Big 3 Upgrade, but as of now no.

Know this isn't relative to your question, but just though I'd mention it.
The amp is connected to the stock "Premium" Boston Acoustics system and it actually sounds very good. The amp is connected using the C2A-CHY Can Bus interface. "The C2A-CHY provides a 4-channel pre-amp output signal for use with aftermarket amplifiers. This interface uses the full range fixed level headunit output in conjunction with CAN-bus messages and delivers a 5v RMS (max) pre-amp output with fading and balancing capabilities.
• 4 channel output.
• 5v RMS (max output).
• Data controlled remote turn on wire

Plugs into the vehicle's CAN bus and provides a stereo RCA audio output for adding aftermarket amplification. Provides full range audio output 20-20,000Hz. Audio output level is controlled by the volume of the factory radio.

Here's a diagram:

I know it's connected to bat with at least 4 Gauge wiring and they added a fuse at fuse box, and there may be another added near the amp.
