Dr. Venkman Posted March 26, 2018 Share Posted March 26, 2018 Our kitchen/breakfast room is one long(ish) room with two pairs of speakers (towards either end). Right now, they are set up as separate rooms in C4, and each is its own output on the audio matrix (Triad AMS-24) and its own zone on the amp (Triad TS-PAMP8-100). We've decided that we will never need to operate the zones independently and that we would like for them to just function as one. Additionally, the speakers are the only thing in the breakfast room in C4 (all of the lights, door sensors, etc. for that area are in the kitchen), so we would rather just not have it cluttering up Navigator. I put in some programming so that the breakfast room follows any time the kitchen changes, current device, volume, or on/off status, and I hid the breakfast room in Navigator. It seems to be working perfectly, but my question is: Was this the best way to do it, or should we wire the speakers in parallel and have it run at 4 ohms (then have my dealer delete the breakfast room altogether). Thanks. Link to comment Share on other sites More sharing options...
sonic30101 Posted March 26, 2018 Share Posted March 26, 2018 Depends if you need the additional amp and or matrix outputs. I would just use y adapters and feed both amp inputs off the same audio matrix zone but if you could utilize the additional amp zone for something then adding both pairs in parallel at 4ohm won't hurt anything Link to comment Share on other sites More sharing options...
Dr. Venkman Posted March 26, 2018 Author Share Posted March 26, 2018 Thanks much. We've got plenty of matrix outputs. All of the amp outputs are currently in use, but we don't have plans to add any more zones, so I don't think we benefit by freeing this one up. I'll just leave it as two zones on the amp, and if we ever need another, I'll know where to get it. You prefer Y adapters to programming that has one matrix output following another? Just for the sake of not taking up an extra output zone, or to save the controller from processing the commands? Link to comment Share on other sites More sharing options...
ichbinbose Posted March 26, 2018 Share Posted March 26, 2018 I would put both speakers on one output of the amp and delete the unneeded zoneSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Dr. Venkman Posted March 26, 2018 Author Share Posted March 26, 2018 Related: do any settings in the amp need to change to pair them and run at 4 ohms, or is it just automatically taken care of by the impedance on the circuit? Link to comment Share on other sites More sharing options...

thegreatheed Posted March 26, 2018 Share Posted March 26, 2018 Use the global input (input 1) for one set of speakers on the pamp8 and link the 2nd zone to the global input with the switch on the back of the amp. Link to comment Share on other sites More sharing options...

You do not think driving two speaker units from one channel will impact the performance of the speakers or perform any different than if both speakers were driven from two separate channels?

ichbinbose Posted March 26, 2018 Share Posted March 26, 2018 No it will not. it will lower the ohms and make it require less power to drive the speakers. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Pounce Posted March 26, 2018 Share Posted March 26, 2018 We really don't know what speakers OP is using. There is a difference. Better or worse is subjective or at least dependent on products, room and content etc. Link to comment Share on other sites More sharing options...
lippavisual Posted March 26, 2018 Share Posted March 26, 2018 Wiring them parallel so the impedance at the amplifier is seen as 4 ohm will not have any sound quality issues. The only differences are obviously the lower impedance at the amp and the other would be a perceived louder overall sound. That’s it. Also, doesn’t matter what speakers they are. This is just basic audio science. Link to comment Share on other sites More sharing options...
zaphod Posted August 6, 2018 Share Posted August 6, 2018 Picking this thread up as I am interested in running two sets of speakers in parallel. It seems like this isn't an issue - it will just lower the impedance of the load to 4 ohms, which (given Ohm's law I=V/R and V remaining constant) will double the current required. What do you have to be careful about for when you do this? Wire with too low of an AWG that now has twice the current? In addition is 4 ohms the typical minimum impedance for a C4 amp, or any regular amp like an AVR? Link to comment Share on other sites More sharing options...
sonic30101 Posted August 6, 2018 Share Posted August 6, 2018 You want a thick gauge when running 4ohm and the ideal size depends on the distance. Most c4 amps will do 4ohm, not all avrs will do it safely. You may also get an impedance matching speaker selector to bring them back up to 8ohms if needed Link to comment Share on other sites More sharing options...

lippavisual Posted August 7, 2018 Share Posted August 7, 2018 For most speakers installed for WHA, 14-16 gauge is more than adequate. Doing a theater with some massive monster speakers? You can move down to 10-12 gauge. Link to comment Share on other sites More sharing options...
