ehall8702 Posted March 7, 2020 Report Share Posted March 7, 2020 I have a taramps MD 8000.1 and have a single run of 3/0 welding wire . A second run of 3/0 coming soon but gonna use a single run for now. The 3/0 is rated for 450a at 100' ( I believe thats what I read) the amp will pull almost 900a at full tilt, which it'll almost NEVER see, one because power is rated at 2 ohm, initial wiring on subs is 2.67 and after rise amp will be seeing roughly 4 ohms . I have 250a fuses and 500a fuses ( accidentally ordered them a while back ) . If the wire is rated 450 at 100' and my longest run is like 15' , a 500a fuse should be sufficient wouldn't it? Let me know if I'm wrong and I'll order appropriate fuses. Thanx in advance. 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

Dual runs of 3/0 welding cable, 300a alternator, 2 Vmax AGMs up front. current sub is a AB XR 12 ( dual 2 ohm) with bottom spider cut out in 2.25 cubes at 32hz Link to comment Share on other sites More sharing options...
CrackFactory Posted March 7, 2020 Report Share Posted March 7, 2020 I run an md8000.1 1 ohm. I have 300a fuses. I have not popped one yet. My box rises from 1 ohm to 3.6 and I've clamped 2600 watts from it. Link to comment Share on other sites More sharing options...

I got the 2 ohm version of the md8k, so at 4ohms I should get 5k out of it. 2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears.

CrackFactory Posted March 8, 2020 Report Share Posted March 8, 2020 I would probably run them if that's all I had around. I think you'll be safe enough with them. Link to comment Share on other sites More sharing options...
