Need Help with new polks to amp

goingcrazy · December 2007

I Have A Thunder 4 channel marine amp in my boat with 4 polk Db 651's with each speaker on its own channel, however I have just added 2 more Db651's to my wake tower. My confusion is how to hook them up without frying speakers or the amp. The amp is rated at 4 ohms 50 watts per channel and can operate at 2 ohms at 75 watts per channed. I want to have the tower speakers hooked up to the two rear channels and all the rest ( inside boat) speakers connected to the two front channels. I thought after reading posts here and other places that I should series wire the inside boat speakers which would reduce the load to 2 ohms, But I then read that all four channels should operate at the same ohm load. When I say series I mean the negative from one speaker goes to postive of next speaker. Any advice would be greatly appreciated as how to do this properly Bob
