Ok two questions about my Combo Amp, its a Fender Bass-80 160 watts. Im a bit clueless about how these works and havent been able to come up with the right keyword in the search feature to answer my questions. I tried looking for a tech manual online at Fender and no luck on my model. Ok first question. My amp has two speaker outputs on the back; one is where the 15 speaker for the combo plugs in and I assume you can put another speaker into the other one. Am I right in this? Second question. Since the amp is rated at 160 watts I am assuming that means with just the 15, it is an EV and I believe it is 8 ohms. Am I right in thinking that if I want to plug in a second cab, say a 2x10 with a horn (tweeter?) that it would have to be rated at 8 ohms? Also would this mean that I am pushing only 80 watts at 4 ohms now? I am somewhat ignorant when it comes to electrical stuff so please dont get too technical in answering. Thanks for any info.
