## Questions & Answers

**Q: Can I use this amp to power 6 speakers infinity reference. Four 6.5, and two 8” speakers.**
A: Our JBL MA704 is a 4 channel amplifier. We'd like to know more information about what specific Infinity Reference speaker you're interested in so we could better provide you with recommendations and set up. Please reach out to our Customer Support. https://support.harmanaudio.com/us/en/

**Q: what is the average amp draw while listening to music?**
A: I don't know but I have installed on a 1000amp battery with another mono amp powering the SUB and I've used it for 5 hours+ without it draining the battery.

**Q: power supply is it 12v-24v**
A: I know it works on 12V because that's how I power it.

**Q: Water proof ?**
A: Marine grade is not waterproof. It will not handle direct contact with water. It will also void the warranty.
