chambers1517 Posted March 13, 2013 Share Posted March 13, 2013 I installed all of my equipment in a bar at the back of my theater room. I have 3 Lascalas in the front along wit an IB sub. I am powering the IB sub with a Behringer EP4000 amp. The amp is right behind us and is really loud. The room is finished and there is no way to run new wires to the IB backroom.I would like to put the sub amp in the IB backroom. Do you guys think there would be any major drawbacks to put RCA connectors on one of the speaker cables currently running from the bar to the subs and feed my sub out on my reciever to the sub amp input?

CECAA850 Posted March 13, 2013 Share Posted March 13, 2013 Why not just install a quieter fan? It's cheap and easy. I believe it's a 24v fan. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted March 13, 2013 Share Posted March 13, 2013 You're also not going to get the LFE (.1) info off a speaker wire. Quote Link to comment Share on other sites More sharing options...

chambers1517 Posted March 13, 2013 Author Share Posted March 13, 2013 What I mean is , put an RCA plug on one end of the speaker wire and plug into sub out on my reciever. Then put a 1/4 inch plug on the other end of the speaker wire which is in the sub backroom and plug it into the Behringer sub amp. Quote Link to comment Share on other sites More sharing options...

chambers1517 Posted March 13, 2013 Author Share Posted March 13, 2013 That is what I need but no way to run the wire, everything is finished. I was thinking of building one with the existing speaker wire 8ga, but was wondering if it would pick up any weird interference. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted March 13, 2013 Share Posted March 13, 2013 I wouldn't use speaker wire to carry a signal. RCA's are bad enough on long runs for picking up noise. Why don't you just change out the fan? Quote Link to comment Share on other sites More sharing options...
chambers1517 Posted March 13, 2013 Author Share Posted March 13, 2013 Looks like a fan upgrade. Thanks guys. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted March 13, 2013 Share Posted March 13, 2013 Before you disassemble the amp, turn it on and see which way the fan blows so you orient the new fan the same way. I think on those it's pulls air from the rear and blows it out the front. Quote Link to comment Share on other sites More sharing options...

Fans in pro amps are for tight enclosed racks. does your ep4000 get hot? iv been running pro amps at home for years and snipped the positive wire on more than i can count. not 1 has even broke a sweat. just make sure you have enough wire to pull it back together to soldier if you sell or use it in a closed road case in the future(there will be a good inch or 2 extra fan wire installed from factory. all without even taking the amp case apart). do some checking around online if you have doubts. no pro amps burning up anywhere in at home use w/out fan. now if the 4000 does get hot buy the quiet fan which is as easy fix as running cables as you are aquiring info about Quote Link to comment Share on other sites More sharing options...
OO1 Posted March 17, 2013 Share Posted March 17, 2013 Since you are having a fan issue -dont forget to look for the direction of the airflow to find the correct unit - the airflow direction is usually indicated on the fan itself - -until you get the replacement - first takeout your fan - remove the paper gasket over the bearing and lubricate the bearing with oil - sewing machine oil or even better synthetic oil used for power tools - - if the fan quiets down - great - that means that the fan was on the way out - -I would call Behringer to see if they have a 24 volts replacement or if your part is under warranty - noisy fans means a worn out bearing section or motor assembly - maybe they were having some quality issues with their OEM supplier -getting a factory replacement that was tested is important - Digikey - NMB - are OEM manufacturers - - I have a lot of good luck with BGW replacement amplifier fans , as long as the airflow is the same - BGW X2500 amplifier fans units are front to rear airflow to cool heatsinks - the bonus is that they last for ever as they are truly very well designed -- take care Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted March 18, 2013 Share Posted March 18, 2013 - if the fan quiets down - great - that means that the fan was on the way out - -I would call Behringer to see if they have a 24 volts replacement or if your part is under warranty - noisy fans means a worn out bearing section or motor assembly - maybe they were having some quality issues with their OEM supplier The Behringer fans are noisey, brand new out of the box. They're not defective. They have an aggressive blade shape which causes noise as they cut through the air. The quieter fans don't move as many CFM, but as noted above, it isn't really that critical.
