400w head

Hey, my bassist and I are pretty much amp noobs. We picked up a GK GLX 4x10 cab yesterday because it was pretty much a steal. Now we're looking for a 400w head for it. We're pretty broke so we're looking for the best bang for our buck. Any help guys?

Thanks
 
I've read up on this thing and I'm really considering it. I was looking at the Firebass head too and I actually like that better. Would running the firebass head with the 8ohm 400w RMS/800w Program GLX cab be safe?

Sure, it would be perfectly safe, just possibly the worst power to weight ratio of any head / cab combination I can think of. The Firebass is rated 275 watts @ 8 ohms. The Nitro will put out around 170 watts at 8 ohms.

What about putting the firebass on 475w @ 4ohms. Thats not the bad kind of ohm mismatch and thats only putting about 18.75 watts extra on each speaker if I'm not mistaken. And what I've been getting from this forum is that putting extra wattage into the speakers is actually kind of a good thing right?

You can't "put the firebass on 4 ohms", it doesn't work that way. The head works at whatever impedance load it's hooked up to. If you run it with an additional 8 ohm cab, then yes, that will be fine, and then the 475 watts will be split in half to each cab, so no power handling worries there.
 
The impedance of the cabinet(s) determines the power range you'll get from a SS amplifier.

The firebass would be a good choice, but, as has been said you'll only be getting up to about 275 watts out of it.

Pfft, the Firebass is my light amp :P

My SVT weighs in at about double that, and there's only about 25 watts more power :P

Oh man I didn't know that. So I'm pretty much screwed at getting a lot of wattage out of 8 ohms without breaking my little bank?
