Fender 350 Rumble combo and Ampeg combo question
Is there any possible way to wire an extension cabinet to a Fender Rumble 350 watt combo amp ?:atoz:
What would be a good Ampeg combo amp that would take an extension speaker cabinet ?
You need to put a male 1/4 inch jack on a two
conductor wire going through a hole you drill in
the back of the cabinet and run it to the internal
speaker. Then install a female 1/4 inch jack in a
hole you drill in back of the cabinet. Run a two
conductor wire between the amp speaker cable
and the female jack. That way you can plug or
unplug the internal speaker and plug in an external
speaker, or the internal speaker, but not both.
Any wires used should be at least 14 gauge wire.
Jacks should be speaker jacks.
The 350 combo is rated at 350 watts at 8 ohm.
That probably means you can only run a 8 ohm
or 16 ohm external speaker.
It's strange. The 350 head will run 175 watts at
8 ohms and 350 watts at 4 ohms. They say that
the two amps are the same, but I don't believe
Thank you ! So you can't run the internal and external speakers at the same time ?
No, I don't see how you can run both
speakers at the same time.
That is a frustrating thing about the 350
combo in my opinion. I've had Rumble
combos in the past and they just seem
like practice amps to me.
I bought the 350 head and can run two
speakers that are rated 8 ohm each
and it seems to have way more umph
than the Combo. I'm real happy with the
But, if you do the installation of the jacks
like I described, you can run a 4X10 cab
and that would probably make a big
improvement in sound.
I did that mod to a Peavey amp I used to
have. That amp had a 12 inch JBL speaker
and I could use it as an extension cab for
a another amp. That wouldn't work as well
for the 350 combo sense the speakers in
the combo are not that good and it would
be a heavy as hell 2X10 cab.
Don't get me wrong. The 350 combo is a
nice amp for what it is, but it should have
been made with a speaker out jack. That
keeps it from competing with other amps
rated at 350 to 500 watts. I think this
situation caused the 350 head to be a real
sleeper of an amp. The head can compete
but few realize that.
That's just my opinion.
But the rest is what I would do if I wanted the option to switch from the internal drivers to external cab.
Thanks for the info. I read somewhere that
the 350 combo ran at 8 ohm and never
Now it makes more sense to me,
