BMS Posted December 13, 2016 Report Posted December 13, 2016 THIS ISN'T A QUESTION ABOUT WHAT MY LOADS' IMPEDANCE IS. So I have 2 Dvc subs I can make 1 ohm by putting the coils in series and the subs in parallel OR i can put the coils in parallel and the subs in series. Which Way would you wire it and why. Either way I have 4 wires running to the amp. If i have the subs in series it is possible but not likely that 1 sub could blow and open the circuit saving the other sub I did actually have this happen once but in most cases id imagine if one blew the other would be damaged anyway. other than that i see no real benefits to sway me to do it one way or the other.
3vil Posted December 13, 2016 Report Posted December 13, 2016 I'd wire it whichever way gave me the best sound quality, spl, or clamp depending on what my goal was. IE run some tests and see what is best suited for your goals.
reedal Posted December 13, 2016 Report Posted December 13, 2016 in the Crossfire Audio subwoofer manual, they state that you should always wire [multiple] subs in parallel, otherwise it can result in less than optimum power sharing and sound. all4spl tested it in a thread on here, and at 51hz tone, he had more impedance rise wired parallel coils/series subs than he did series coils/parallel subs, as measured by the termlab. Edit: I added the word multiple for clarification.

So, two dual 1's wired series parallel will give me a final impedance of 1ohm?
reedal Posted December 13, 2016 Report Posted December 13, 2016 yes 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
8ten8 Posted December 13, 2016 Report Posted December 13, 2016 yes Got it, Thank you. I'm going dual 1's this time.

8ten8 Posted December 13, 2016 Report Posted December 13, 2016 Why not dual 4s and straight parallel? Right, that's how I've done it in the past but from what I just read, it seems like subs run more efficient wired in series parallel. I often wondered why dual 1's existed
reedal Posted December 13, 2016 Report Posted December 13, 2016 Who's to say parallel/parallel is not more efficient than series/parallel? have you tested it? I haven't. I only said that in one test on one set of subs, there was less rise wired series/parallel than parallel/series 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
8ten8 Posted December 13, 2016 Report Posted December 13, 2016 Ok efficient is the wrong discretion. Less box rise sounds good to me. I'll try it. description
