baller95 Posted March 5, 2016 Report Share Posted March 5, 2016 Hey guys, I recently picked up two Alpine SWS-10D4 subs and I'm looking at getting the Pioneer GM-D9601 amp. The subs are rated at 500 watts RMS and they're dual voice coil. The amp is capable of producing 800 watts RMS at 2 ohms and 1200 watts RMS at 1 ohm stable. My question is if I should run my system at 1 or 2 ohms. I'm sure the subs can handle a little more than they're rated for and from what I've read the amp puts out what it's rated for if not a little more. So, should I run my subs (1000 watts RMS combined) slightly under powered (800 watts RMS @ 2 ohms) or slightly overpowered (1200 watts RMS @ 1 ohm)? Also, 4 gauge wire should be sufficient for the amp right? And 8 gauge for the speakers? Thanks! Link to comment Share on other sites More sharing options...
reedal Posted March 6, 2016 Report Share Posted March 6, 2016 You can't run that amp at 2ohm, because you have two D4 subwoofers. Only 1ohm, 4ohm, or 16ohm. So, run it at 1ohm, make sure you have the gain and filters set properly, and your wiring should be fine. 8ga for the subs is a little much for that small of power, I'd go with 12ga personally. But if you already have the 8ga then use it.

The Pioneer amp however has two output terminals but it's called a monoblock amp for some reason.For 1 ohm it'll be a bridged connection but 2 ohms will be like this right?

ShadeTreeMechanic Posted March 6, 2016 Report Share Posted March 6, 2016 If that is a mono amp then it will be 1 ohm. If it was a two channel amp then it would be 2 ohms on each channel. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...

No, the two pair of outputs is for simplicity in wiring. It's just a mono (one channel) amp. So you are not able to wire to 2 ohm. Only 1ohm, 4, or 16ohm SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
MotorCityFats13 Posted March 6, 2016 Report Share Posted March 6, 2016 amps like this are good for breaking down the power each cable will carry to each voice coil / sub.... I run my amp at 1ohm but run separate cables to each voice coil.... so in turn I get a split of power going through 12awg speaker cable... so instead of 1200rms going through 12awg its 600rms going through 2 runs of 12awg but sub still gets the same power but with less parasitic loss through cable size .....on the amp the terminal blocks are joined together internally Link to comment Share on other sites More sharing options...

Alright so I guess 1 ohm it is! Thanks! Link to comment Share on other sites More sharing options...
