So yeah, just got this big ol amp (about 50 lbs!) for $3 at a yardsale, tested and works perfectly. I would like to incorporate it in my home theater setup, 7.1 right now. The whole system is powered by my main Onkyo AVR and this is my firs foray into the world of pre amps etc. I would like to use this amp to power a sub placed in an enclosure that I build. The amps manual says it is rated at 600w bridged mono @ 4ohm. After some research it seems like the general opinion is that is a modest continuous number for the amp.


So my question, can i run an rca to xlr adapter from the sub out on my reciever to the amp and use this amp to sufficiently power a sub? Any sub recommendations for this power output?


Thanks for the help in advance.


here is a link to the manual

Ha ha! $3!!!??? I've been using this amp for 20 years to power my JBL and now my (distorted) Urei 809 speakers! I've been looking at modern AVRs and wonder how the specs of the 6230 stand against them... I've always been happy with it (after JBL serviced it).


Anyway why don't you just use RCA to 1/4" phono cables to go to the amp? As far as I understand it, this old tank should be able to power most subs sufficiently.


Hope it works out!

These Old Amps are tough to beat for sound quality and high current power.

Yes I agree, I have this amp. The XLR uses and old configuration and the polarity is not what is used today. The 1/4" input is normal. I would use an RCA to 1'4" cable. Monoprice has plenty of options here.

This amp is a beast and i've never been able to get one to shut down, even using them to DJ for 10 hours straight at about 90% output. You got a great deal, make sure you put the bridging switch in the right place and use the right output connectors for speakers, as they change when using in bridge mode.

Awesome find!

The JBL 6260 uses those great sounding Sanken output transistors, with a good sized transformer, and was designed for sound quality. It uses the same design criteria as all Harman Kardon amps do. Do not let the pro sound scare you off, because this amp is every bit an audiophile quality amplifier. I have compared it to an Adcom 555 and a Hafler 500, and it can more then hold it's own.
The overall sound is rather on the warm side, not a bit bright or harsh.
The Adcom 555 has a little more detail, but it can sound bright and harsh at times.

Be sure and give it some room for cooling, as the JBL 6260 amp appears to have a high Bias, and is known to generate some heat.

The JBL 6290 is a total BEAST, if you can ever find one ?
