Boon Posted December 10, 2007 Report Share Posted December 10, 2007 Hi guys, I have a Schneider SPA-7000X. It's exactly the same amp as the Celestra DA6K and American Bass VFL 400.1 as well as I think one of the SPL Dynamics Amps. Anyway. It's rated down to 1 ohm (obviously, being a monoblock...) and according to the Celestra manual it can be loaded down to 0.5 ohms (I think even for daily??) Anyway, I'm about to buy a new sub, most likely an Atomic APX12. I'm wondering what coils to get, basically. I can get a Dual 0.5 which will give me 1 ohm for daily and 0.25 ohm for burps. Basically I'm just wondering if this amp will handle 0.25 ohms (plus impedance rise...) I have heard anecdotal stories of them being run at 0.25 for burps but I was wondering if anyone here has any experience with them. Cheers. 10.x volts fo' life!

andym85 Posted December 10, 2007 Report Share Posted December 10, 2007 .25ohms is super low....the only amp i know of that is capable of that is IA..no first hand knowledge of the amp you listed...but i would be extremely skeptical/careful if you are to burp any amp at .25ohms i likes me some audio stuff...

LeVeL-G Posted December 27, 2007 Report Share Posted December 27, 2007 i have burped my solar audio 5000D (similar to the celestra da6k) at .38 ohm strapped ( .19 ohm per amp) but you have to roll the volume slowly if you don't have enough battery power. i run a optima d34 + a C&D Tech 12475. The amp goes into protection before i can finish my roll. Box impedance rise is what you should concentrate on, try and get the final impedance after rise to .9 ohm. Update: keep the supply voltage above 10.5 volt and the amp will not go into protection. Link to comment Share on other sites More sharing options...
