Ask a Question
  • Is the Boom88 daisy chain compatible, or would I have to run each one separately? Would they work as a pair off a single RCA (single RCA to double RCA adapter) or would they be better ran as a pair off of speaker level inputs via the UW1 adapters?

    You can use UW1 or "Y" RCA plug to split the signal between two BOOM 88
    Source unit 's  Gain or volume should be adjusted accordingly

  • Does the Massive boom 88 active subwoofer contains a built in HiFi Capacitor or do I need to buy the capacitor separately? Is this unit CEA -2006 compliant? Is this unit compatible to Alpine Type E 6.5" Coaxial 2 Way Black Speakers - SPE6000 ?

    It is 2006 Compliant and you would need the UW1 Adaptor or any High to Low convertor if you plan on using speaker leads instead of RCA's. We do not know enough about the Alpine Type E speakers although we do not see reason why they could not be used with them.
