Tobes49 Posted August 18, 2006 Report Share Posted August 18, 2006 Got a rockford fosgate punch amp. Thought it was 1 ohm stable but just checked and it only 2 ohm stable, What problems could it cause running it at 1 ohm? Link to comment Share on other sites More sharing options...
Cupramax Posted August 18, 2006 Report Share Posted August 18, 2006 erm, insufficient load on the output stages of the amp with the result being KABOOOM... enough? Link to comment Share on other sites More sharing options...
Paul Posted August 18, 2006 Report Share Posted August 18, 2006 Ohms law. <u> Voltage (V) </u> Resistance ® = Current (I) Halfing the resistance, puts the amp closer to short circuit and also doubles the current flow. example with a 12 volt circuit. 12 volts(V) connected to 2 Ohms® = 6 Amps(I) 12 volts(V) connected to 1 Ohm® = 12 Amps(I) works the same same regardless of voltage applied. whether it be 2v or 240v. Not recommended. Link to comment Share on other sites More sharing options...
Tobes49 Posted August 19, 2006 Author Report Share Posted August 19, 2006 I've been running it now at 1 ohm for a while with no problems. There a lot of cooling to it and the amp not being run very hard. Would it be the amp would run hotter? i've got a spare amp sitting in the garage so i'll run this one till it goes KABOOOM Link to comment Share on other sites More sharing options...
Paul Posted August 19, 2006 Report Share Posted August 19, 2006 yes i would expect it to run hotter and draw more current. So i would make sure its well ventilated, and that your feed cables are upto the job, with suitable fusing, perferably fused within 18 inches" of the battery or closer. If its running then its either well engineered and over spec'd or pure luck. Link to comment Share on other sites More sharing options...
Tobes49 Posted August 19, 2006 Author Report Share Posted August 19, 2006 There 2 guage cable from the battery 120Amp fuse 2" from the battery then 4 way splitter with seperate fuses 40Amp fuse then 8 guage cable to the amp. I would go with the well over spec, The best amp I have ever seen put together. Seen people running 18+ volts into these amps!!!!! Anyway took the sub out rewired it for 4 ohm's It not as loud now but much more punchy and crisper on fast notes, it also more than loud enough for me so i'll leave it wired 4 ohms.
