Alphasonik 2x10" PSW 810 Subs + powercap/cables/amplifier ?

I am selling my complete set of car subwoofer equipment now I have a new car and have no need for these. These subwoofers are the psw 810 series and have been amazing while I have had them and some of the best subs Alphasonik have made. Also in the sale is a Directed D2400 class D monoblock amplifier and a Directed 2.5 Farrod power capacitor plus a 4 guage wiring kit. Below are the specs for the subwoofers/amplifier/power cap. Due to the amplifier being 1 Ohm stable, the most powerful setting, and the subwoofers being dual 2 ohm coils, they have been wired together to push 1200 watts max each, easily pushing the full 800 watts rms.This amplifier therefore gives out 1600 watts rms with peak at 2400 watts. This is further increased by the 2.5 farrad power capacitor which stores power from the battery so power is drawn quicker. Directed D2400 Amplifier: Class-D Monoblock Amplifier Super-efficient Class D PWM design runs much cooler than conventional amps RMS Power Output: 400 watts x 1 chan. at 4 ohms 800 watts x 1 chan. at 2 ohms 1200 watts x 1 chan. at 1 ohm High-speed MOSFET switching power supply High-current complimentary Class D MOSFET outputs stable into one ohm loads Thermal, DC offset, reverse polarity, and short circuit protection with status LED Continuously variable 12dB/Oct low-pass crossover Switchable 24dB/Oct. subsonic filter Switchable 8dB bass EQ Switchable 180° phase inversion Remote subwoofer level control Master/Slave Function Variable input sensitivity: 150mV - 7.5V Chrome-plated wire terminals and RCA connectors ensure maximum signal transfer Rugged 2-piece heatsink and cover RCA Outputs: 1 pair LED/FAN Connector: provides power for optional LED light or cooling fan Dimensions:13-1/4"L x 10-1/4"W x 2-1/4"H Alphasonik PSW 810e x 2 10" 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 RMS power rating: 800 watts 89dB efficiency Frequency response: 29 - 500 Hz Dual 2 ohm 2 1/2” Voice Coils 8 gauge input terminals Mounting Dimensions — Depth: 154mm / 6 1/8” Through Hole: 225mm / 8 7/8” Diameter: 258mm / 10 3/16” 2.5F Directed power capacitor 2.5 Farad Capacitor Working Voltage - 16DC Surge Voltage - 18DC E.S.R (Euivalent Series resistance) - 0.0015 ohm at 120hz/ 25º C Capacitance Tolerance - ± 10% Reverse pole connecting PCB buzz warning function. If the cap is connected incorrectly by reversing the positive and negative wires during installation process, the PCB will issue a 45 second noise to warn you. Hi-end platinum plated 100% brass solid parts and chrome plated metal cover Over voltage limit and low battery voltage limit warning. When the system voltage peeks iver 17 DCV or LESS than 10 DCV. The buzzer on the PCB will issue an audible noise warning. Multiple small capacitance capacitors linked to provide the lowest inner E.S.R and largest moment discharge power Owned since new and have never been over used, very slight wear on subs simply from being used in the boot.
