I have an eclosure with 3 JL Audio 8w0's currently run from 2 channels (bridged to mono) by a Kenwood KAC 8401 4-channel amp.(the other two channels running front speakers). I'm wondoring if this setup is OK; for the three single voice coil subs powered in this manner? I plan to add a dedicated mono sub amp, but not wanting to spend the money right now because of the install and additional wiring kit cost. Thanks
