johnarias15 Posted July 19, 2012 Report Share Posted July 19, 2012 Hi Guys I put a system in for my friend who has 2 10" Digital Designs 510 Dual 4 ohm coils. The amp is a Crossfire C3 501 that puts out 500 watts RMS at 1 ohm. We are also running 8 gauge Power wire. When I have the subs wired to 1 ohm, they cut out on a song with low notes or when the volume gets too high. I have the amps gains set correctly with a SMD DD-1. And I know its not the Amp because I have the exact same amp in my own truck which makes the subs cut out. To make them to stop cutting out I wired the subs to 2 ohm. But I want it wired to 1 ohm to be louder. Could this be an electrical problem or something else?

Kranny Posted July 19, 2012 Report Share Posted July 19, 2012 whats the voltage dropping to when it cuts out? Quote Link to comment Share on other sites More sharing options...
HunterJohnson Posted July 19, 2012 Report Share Posted July 19, 2012 how long of a run is that 8 gauge wire? It is most likely an electrical problem, do your lights dim?

notorious97200 Posted July 19, 2012 Report Share Posted July 19, 2012 You can wire your subs to 1 or 2 Ohms ? How an you do that ? 8 gauge may not be enough. But I am not an expert.

But I am not an expert. yeah how the hell did you wire 2 dual 4 woofers to 2 ohms? its impossible. unless you only used one sub. Quote Link to comment Share on other sites More sharing options...
CleanSierra Posted July 19, 2012 Report Share Posted July 19, 2012 I'm confused, did you say you KNOW it's not the amp because you have the same amp in your truck and the subs cut off? Maybe you wrote it wrong or my English is failing, but isnt that a contradiction? Also, as previously said, you can only wire 2 Dual 4 ohm subs to a final load or 1 ohm or 4 ohms, no other way, I promise. Quote Im not the one you want to try to troll. Just a fyi for you.

rockFord_Expedition Posted July 20, 2012 Report Share Posted July 20, 2012 SMH For starters... -Make sure all connections are secure.. -How long is the run of 8ga? -What is the rating of the fuse you have installed? -Pics of ground(s) connections -Where did you tap into power at? -Describe "how" you wired subs Quote Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire Link to comment Share on other sites More sharing options...
Socky Posted July 20, 2012 Report Share Posted July 20, 2012 What kind of 8ga are you running, it may have to much resistance and not sending the proper voltage to the amp, what is the voltage at the amp before it cuts out? What are you exactly reading ohm load at the amp?

johnarias15 Posted July 20, 2012 Author Report Share Posted July 20, 2012 Sorry but I meant to say they are now in a 4 ohm load. I haven't been able to check voltage yet but I planning on doing so later this evening. I also want to clarify that I have 2 DD 8's in a 1 ohm setup with the same amp in my truck which plays fine. But trying to check everything I took my amp and put it in his truck and it still cuts out. The run of 8 gauge is possible 5 to 6 feet. The system is installed in a 2000 GMC Sierra Single Cab. The fuse is rated at 80A. When the subs cut out the amp does not power down or go into protect mode also. Currently the subs are wired like this. But the subs cut out wiring like this The power cable is directly wired into the positive battery terminal on the battery with the proper connectors. Also my friend has led dark blue interior lights so its hard to tell if they are dimming but a voltmeter test will probably tell me everything.
