Hi low-enders, I realise that is probably an often asked question, but a search didn't produce an answer that satisfied me: I bought a Rockit 120 Bass amp, and the seller threw in a cab with a 15" JBL speaker, which was blown. I've sent the speaker off for repair. In the mean-time I found out the speaker is rated at 8 ohms, and the amp puts out 4 ohms. My question is then - what are the ramifications, if any of using these two together? Would I get better performance if I put another 8 ohm resistor in parallel with the speaker to lower the resistance to 4 ohms? Thanks for your time.
