I have used the stickys and the search and cant find the answer. I have an ampeg 410 cab. It has all 4 of its 16 ohm speakers wired in parallel. I wired the first and last speaker in series and the two middle speakers are paralleled together. When I check it with a meter it says 8 ohms but I wanted to hear from you guys before I powered this thing up. I realize that if I lose a speaker that is in series with the rest of them then they will all quit. Is this the right way to do this? I got a great buy on an 8 ohm 15" JBL and I want to stick it under the 410 and the two 8 ohm cabs would = a 4 ohm load which is what I want. Thanks in advance.
