Wow, that's one massive power amp! I did a quick review of the photos, and here's my 2 cents.

The XLR jacks were added after it left the factory, definitely not original.

The photo shows that the current speakers are wired in series. You need to check the impedance of each of the individual speakers and see how you can wire the cabinet to take full advantage of the power of the head.

And Pleat erred in his last post, if all four 16 ohm speakers are wired in parallel they will equal 4 ohms, not series.


Jep, it's really a monster. I like it a lot. Also because of the complete lack of design whatsoever. It's just what it is, a box with knobs.
About the 4-15, i'm getting rid of it. I'm going to take out the speakers (those are not original), and keep them for "just in case". A guy i know is a HUGE Kustom fan/freak. Blue Cheer lover, Stoner etc. and very serious, and with a tremendous amlifier collection. Also a lot of vintage Kustom gear. A couple of the 3-15 collums for example, you name it, being there is like a dream. Sunn tops piled up. Well, you get the picture. Anyway. He can have the cabinet, and that gives me a good feeling, it's in good hands.

I tried the top on my Peavey 215 cab, who looks pretty small next to the Kustom 415, and it sounds splendid. So i'm happy. I was looking for this top (a bit ashamed, but almost on a daily basis) eversince i bought my Kustom III bass in 2003. It's so extreme loud and warm. Wow.
