I have an amp that is advertised as 150 watts. It even has 150 in the Model of the amp TBX150H. It can be used at 8ohms (100W) or 4ohms (150W). I had my cabinet wired previously at 16 ohms. Sounded thick. Then I rewired it to 4 ohm to get that advertised 150W. Is there a reason that the sound (to my ears anyway) from the amp/speakers sounds better BEFORE wiring the 4ohms? It would seem that if the thing is advertised as 150W..that 4ohms would be the preferred setting. I thought it sounded fuller/thicker when wired at 16 ohm. Or is it just my ears tricking me?
