So I recently procured a Hartke LX5500 head (500W @ 4ohm) and am wondering if (2) 4x10 (400w @ 8ohm) cabinets (410XL V2) would be effectively powered by that head since splitting the ohm load between two cabinets would result in 250w per cabinet @ 4ohm? Am I just fridge hungry or is two better...

Hello, The fender rumble 500 watts combo works as follows: Without an extension cabinet: 350W with 2/16 = 8 ohm (internal speakers) With an extension cabinet: 500W with 2/16= 8ohm (internal) - extension 8ohm = 4 ohm. I never use an extension cabinet, and my speakers are sounding funny lately...

So would the following head + cab combo work well? GK legacy 800 (800 watts max output, 2 ohm minimum load) with GK CX410 4 ohm cab (handles 800watts) + GK CX 115 8 ohm cab (handles 300watts). I think this would be awesome. So (8x4)/(8+4) = 2.666 ohms would be the total ohms in parallel, and...
