reedal Posted August 10, 2014 Report Share Posted August 10, 2014 I tried googling this, and searching this forum only gets you so far towards finding an answer since it finds the keywords, not what you actually searched. So here's my question. If you have a mono block amplifier stable down to one ohm, and it has two speaker outputs on it (two positive, two negative), and you have two dual two ohm subs, could you not wire them to give the amplifier a one ohm load each? A single dual two ohm can be wired in parallel to one ohm correct? So both subs wired to one ohm individually, and connected to the amp, one to each speaker output, could that make a one ohm load on the amp? Or would that wire them in parallel making a .5 ohm load? I'm not sure how the dual speaker outputs on the mono block amp work exactly, i imagine it's parallel since you get the same output no matter which one you use or even if you were to bridge the two outputs. No difference in output for mono block. So is that a possibility, or is that still wiring them in parallel as a .5 ohm load?

reedal Posted August 10, 2014 Author Report Share Posted August 10, 2014 That's what i figured, but felt it was better to get a second opinion. Thank you. Am i correct in saying that wiring it as such would place it in a .5 ohm load?

truthsayer Posted August 10, 2014 Report Share Posted August 10, 2014 Here these diagrams will help any confusion. Option 1 (parallel/parallel) = 0.5 ohm load Voice coils wired in parallel, speakers wired in parallel Recommended Amplifier: Stable at 1/2 ohm mono Option 2 (series/parallel) = 2 ohm load Voice coils wired in series, speakers wired in parallel Recommended Amplifier: Stable at 2 or 1 ohm mono Option 3 (series) = 8 ohm load All voice coils wired in series Recommended Amplifier: Stable at 4, 2, or 1 ohm mono truthsayer Link to comment Share on other sites More sharing options...
reedal Posted August 10, 2014 Author Report Share Posted August 10, 2014 No, those diagrams I've seen over and over for the last five years. That's not what i asked. I asked about each sub being wired to one ohm individually, as which is possible when both voice coils on the single dual two ohm sub are wired together in parallel, and then both subs (now being wired INDIVIDUALLY at one ohm) connected INDIVIDUALLY to each speaker output on the amplifier. Those diagrams quite clearly have the subs wired together, and going to the same output from the amp. Doesn't remotely touch the question. Thank you though.

If each sub is wired to 1 ohm and run to its own + and - on the amp, the final load the amp sees is .5. Due to the speaker channels running parallel inside the amp.

REVOofRustler Posted August 10, 2014 Report Share Posted August 10, 2014 The outputs on the amp are not two seperate channels. Think of it like a distribution block on both the positive and negative terminals. The multiple inputs/outputs are there only for ease of installation. So, yes, you would end up with a load of .5 ohms at the amp because you are wiring the two "1 ohm" subs in parallel at the amp. 2002 Dodge Dakota 4.7 club cab - Sold 2004 Audi S4 Avant - Fi and Crescendo - Stock Bose System - http://www.stevemeadedesigns.com/board/topic/147725-2002-dodge-dakota-end-of-the-road/?hl=%202002%20%20dakota 136.4 Sealed @ 29hz 137.0 Drivers window open @ 26hz Link to comment Share on other sites More sharing options...
truthsayer Posted August 10, 2014 Report Share Posted August 10, 2014 If op doesn't understand monoblock and the diagrams, not sure what else can be done to make him understand. truthsayer Link to comment Share on other sites More sharing options...
reedal Posted August 10, 2014 Author Report Share Posted August 10, 2014 Thats the type of answer i was looking for. Posting a picture that shows a different setup than that which was asked doesn't answer the question asked. I understand how the diagrams work. As stated in the question, i said i imagine that the mono block amp speaker outputs are in parallel, You must have missed that part. It was a simple question that you answered with a picture that visually depicted a different setup than what was asked about. I was unsure of the mono block dual speaker connection, but that was made clear by Orion and REVO 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...
truthsayer Posted August 10, 2014 Report Share Posted August 10, 2014 ^^^^^^^^^^^^^ I stand by my statement. If you can look at the diagram and understand, well SMH. It can;t be much simpler. you just remove one sub from the diagram for each input. or just use one speaker connection for both subs. truthsayer Link to comment Share on other sites More sharing options...
