Hi I need a bit of help with all these ohms which I have no understanding of these. I have an EB 180 and I have upgraded the speaker to a Soundlab 1041f. its a 15 inch 400 W speaker rated at 8 ohm. My question is can I add the original blue line 150 W speaker which I have put in a cab, its rated at 4 ohm? I dont want to add too much and cause damage to my amp. Help please
Gary
