## Questions & Answers

**Q: Can i run six 8 inch prv 8mb450 8ohm speakers with this amplifier or should i get something bigger**
A: Since you have 8 ohms speakers it would not be best to load them on a 4 channel amplifier because of the impedance, the amplifier will not provide enough power to them.
The best way to provide them power is a PRV SQ3500X at 1ohm! You need to wire all 8 speakers in parallel to 1 ohm.

**Q: 4 channels w/3 outputs, does it share power across left & right channel. I set gain by ear, l/r diff. Voltage with dmm but equals bridge power of amp?**
A: The red light was on once I connect the amp, and the new apm is working perfect

**Q: 800watts por cada canal? Oh 800 watts por todo**
A: Son 800 Watts en total. Estas son las configuraciones posibles:

Potencia RMS en 2 ohms 12.6 V 4 x 225 W RMS (ESTÉREO)
Potencia RMS en 4 ohms 12.6 V 4 x 140 W RMS (ESTÉREO)
Potencia RMS en 2 ohms 13.8 V 4 x 260 W RMS (ESTÉREO)
Potencia RMS en 4 ohms 13.8 V 4 x 165 W RMS (ESTÉREO)

**Q: Will 16.0V be too much?**
A: Just need 14.3 to work good
