    Default How should I hook up this sub & amp?

    AMP
    KenWood KAC-7251

    800 Watts max power
    150 Watts x 2 max (4 ohms) RMS
    460 Watts x 1 (4 ohms) RMS
    Power Output at 2 Ohms, at 14.4V (1kHz, 0.8% THD): 230 Watts x 2

    Bass boost via wired remote control
    Frequency response 5Hz to 50kHz
    Built in low pass filter (150Hz)
    Built in variable high pass filter (50 - 200Hz)
    Speaker level input
    Gold plated input & output terminals
    Integral cooling fan

    SUB
    Alpine SWR-1221D (12") Dual Coil
    Max Output Power 1000 Watt
    Nominal Output Power 300 Watt
    Sensitivity 87 dB

    How should i hook this up? One coil to each channel?
    Bridge amp then connect coil in Series?
    Any recommendation would be great. (im pretty newbie at this.)
    Schematic would be great, otherwise descriptions work as well.

    Since the AMP you selected (KenWood KAC-7251) can ONLY output to one channel stably in 4ohm mode, I would strongly recommend option # 2.
