mcgonzi Posted March 16, 2016 Share Posted March 16, 2016 Is it possible to bridge the KA-1000 to use it as a Mono Amp?I have 4 Subs SW-120 THX and would like them to run with mono amp so each channel can be controlled separately but at the sometime I don`t want the output to be reduced Hope to hear a good solution Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted March 16, 2016 Share Posted March 16, 2016 Sounds like a quick way to fry it in my opinion. That amp is built specifically to run one or two of those subs. If you have four find you a second amp. 1 Quote Link to comment Share on other sites More sharing options...
mcgonzi Posted March 16, 2016 Author Share Posted March 16, 2016 I have 4 Subs and 4 Ka-1000 I would like too know if the amp is bridgeble Using 1 amp with 1 Sub does not give the same power of 2 subs in one amp Quote Link to comment Share on other sites More sharing options...
billybob Posted March 16, 2016 Share Posted March 16, 2016 Using 1 amp with 1 Sub does not give the same power of 2 subs in one ampThat is correct if the same as an RSA-500 Klipsch sub amp. it gives more power if just 1 sub is attached. I would err on the side of caution about any bridging as per previous poster. It is a purpose built amp. Good Fortune! Quote Link to comment Share on other sites More sharing options...
jjptkd Posted March 16, 2016 Share Posted March 16, 2016 (edited) Running a single amp on each sub should yield the same output (power to single speaker) with twice the damping factor and more head room than running two subs on a single amp. The ka-1000 is rated 500 watts into a single speaker at 8 ohms and 1000 watts into 2 speakers at 4 ohms and since there is no separate controls for the speakers I'd guess that the outputs are wired in parallel to effectively drop the output of the amp to 4 ohms doubling the power but if I understand that process correctly it also cuts damping factor in half. I assume that you're running the Klipsch KW-120's? I'd try just hooking them up individually and see if that works for you, if you're not getting enough output that way order up 4 more of the subs and just run them in stacks. Good luck!

colterphoto1 Posted March 16, 2016 Share Posted March 16, 2016 It IS a mono amp. It just has two outputs for convenience to wiring to the suggested complement of two KW120 subwoofers. I wouldn't run more than that with it or risk blowing it up. If you need to run four cabinets, that would entail using 2 KA1000 amps. You could use other amplifiers with much more power, but you'd lose the automatic features, phase fine tuning, and any active eq built into the KA1000 by the Klipsch engineers. I'd get a second KA1000 if I were you. Or a completely different sub system if you need that much output. How large of a room are you playing to? 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted March 16, 2016 Share Posted March 16, 2016 I'd get a second KA1000 if I were you. He has 4 amps already? Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted March 16, 2016 Share Posted March 16, 2016 I'd get a second KA1000 if I were you. He has 4 amps already? he needs 4 more amps and 12 more subs. I mean what cooler than 16 subs? Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted March 16, 2016 Share Posted March 16, 2016 I'd get a second KA1000 if I were you. He has 4 amps already? no - he's attempting to drive 4 cabinets with one amp. 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted March 16, 2016 Share Posted March 16, 2016 I have 4 Subs and 4 Ka-1000 I would like too know if the amp is bridgeble Using 1 amp with 1 Sub does not give the same power of 2 subs in one amp From what I'm reading here, he has 4 subs with 4 separate amps. Instead of only getting the 500 watts per amp at 8 ohms with 1 speaker he's asking if there's a way to bridge the amp to get the full 1000 watts (at 4 ohms) to a single speaker cabinet.

colterphoto1 Posted March 16, 2016 Share Posted March 16, 2016 OH, perhaps that's it. In that case. No - it's a MONO amp as it stands. There do not exist two separate outputs to bridge together. 1 Quote Link to comment Share on other sites More sharing options...
babadono Posted March 16, 2016 Share Posted March 16, 2016 Could you hook two speakers in parallel across the + outputs of 2 amps and invert the signal into one of the amps? Quote Link to comment Share on other sites More sharing options...
Scrappydue Posted March 17, 2016 Share Posted March 17, 2016 How about use the amp as intended and not destroy your gear. They don't need 1000 watts otherwise Klipsch would have made it a 2000 watt amp. 1 Quote Link to comment Share on other sites More sharing options...
