[QUOTE="Jepalan, post: 8152781, member: 655519"] I looked at the amp's manual. It shows stereo inputs and says nothing about mono inputs. It looks like a basic 2-channel amp that is internally bridged to make it "monoblock". In order for a bridged output to work properly, there has to be a signal present on both L and R inputs. I highly recommend you use a Y-Splitter into this amp. Y-SPLITTING DOES NOT CUT THE VOLTAGE IN HALF - read on, the example is typical: Use this calculator to figure it out. [URL="http://www.sengpielaudio.com/calcula...agedivider.htm"]http://www.sengpielaudio.com/calcula...agedivider.htm[/URL] ------------ Vin = Enter HU output voltage Z1 = Enter HU output impedance Z2 = Enter Amplifier input impedance Zload = Enter Amplifier input impedance. ------------ Example. Vin = 5 volts Z1 = 200 ohms Z2 = 20,000 ohms Zload = Don't enter anything, default is 1 megaohm. ------------- The HU outputs 5V, but with amplifier connected, the loading effect of the amp causes the voltage to be 4.95 volts. If you connect another amp, lets say it also has 20,000 ohms input impedance, the calculator says; ------------- Vout = 4.90 volts With one amp, 4.95v With two amps, 4.90v ------------ *What if* Vin = 5 volts Z1 = 2000 ohms Z2 = 10,000 ohms Zload = 10,000 ohms With two amps, 4.54v ------------ [/QUOTE]
