Ask a Question
  • How do you run the speaker wires. You bridge them or run 4 wires out to amp?

    It all depends on the amplifier and how your final impedance will be. Most people tie both POS together and both NEG together for a 1 ohm final load for a single woofer. 

  • How big of a box can I put one 15.2

    Please review our manual for box specs https://cdn.shopify.com/s/files/1/0658/1297/files/HIPPOXL_USER_GUIDE_2020_Combined.pdf?v=1580491688 . Thank you for your Massive Audio support.

  • what is frequency response will it hit 20hz

    Hello Matthew, The HippoXL152, depending on enclosure and amplifier settings, will be great from 26hz to 90hz or so. Thank you, Aaron

  • How bout if you have 2 152s an a 1 channel mono block.how do you wire them if your amp stable at 1 ohm???

    You would only be able to wire a pair of dual 2 ohm speakers at a 0.5 or 2 ohm final load. So if you have a 1 ohm stable amplifier you would not be using 100% of the power. This amplifier would be best suited for 1 dual 2 ohm woofer however there is nothing wrong with running a final 2 ohm load as the amp will thank you for not pushing at its lowest impedance. Your best option is to use a 2 ohm mono amplifier like our BP4000, BP6000 or BP8000 for example.
