How do I hookup 2 Subwoofers Togerther

How do not have LFE ON MY PREAMP

i USE Y connectors on my preamp to run one Sub (WORKING FINE) How do hook up another sub Sunfire Subwoofer

This from the manual

Aways drive each woofer through the
Left/Mon input even though you are driving one woofer with a right channel drive
and the other with a left channel drive. If
your pream pli fi er has a single sub/LFE
output, use a Y cable to split it into two
outputs

Just as the manual says. Use a splitter to run 2 single RCA ( just split them down the middle..and make sure they're long enough ) to each sub. It really doesn't matter if its left or right signal because sub bass is mono.

The challenge with daisy chaining (paralleling) two subwoofers from a single preamp output is you are presenting a significantly lower resistive load to that channel. I would not advise such.

With two subs, split each channel driving a single sub to balance the load difference.

Another question please. I have 2 outputs on my Integrated Rogue CM 2, R+L each fixed and variable. Using "fixed" right now. Should I Use 2 "Y" connectors off of fixed and hook up the second sub Both subs Rythmik 12SE R+L? No speaker hook ups on these Servo amps.

Maybe I'm missing something or perhaps your subs don't accommodate speaker level hook-up. I've hooked up subs speaker level for years without issue.

If you want the subs to track the relative volume of the speakers, use the variable.

I have been told the opposite use "fixed" to keep the path simpler. I'll try it again. THX!

the subwoofer output will be constant, i.e. fixed regardless of volume control.

 

Hope you are enjoying your Rythmic subs, posted on January 7, 2024 at 07:33:01

I would use 2 cables from the variable outputs on integrated (L/R) to your L/R subwoofers.
That way the subwoofer will rise/fall with the output of the integrated, to main speakers.

I tried that with my Musical Fidelity A1-2008 class A amp to my HSU sub that has speaker level inputs, and the A1 amp displayed a fault indication immediately on it's LCD display.

Some amps apparently can't support that type of sub connection safely. I should add I am an experienced hifi guy and very careful with my speaker hookups...

Yes, there's always that possibility. A few years back I knew of a classd amp manufacturer who cautioned against it, but it seems pretty rare. I only have one solid state amp and it's Classdaudio Mini Gan3. Tom (the designer) endorses speaker level hookup. The exception being REL where he says not to hook up the ground (black) wire. So it's always a safe bet to contact the manufacturer if you feel there might be a compatibility issue.
