I got my big 3 done, now I have my brx 1400.1d wired up. voltage stays at 14.2, dips to 13.6 at most. I have 1 obsidian 15 wired to 2 ohms getting 900 rms but I can run it to 1 ohm and give it 1400.. if I'm gentle with my gain will it be okay? or am I better off wiring my 2 12 p3s to 1 ohm and play it safe? I'm not looking for a long lasting setup. just something to get me by until I upgrade to soundqubed.
How are you going to drop the 1 sub from 2 to 1 ohm?
If you have a single sub wired to 2 ohms than how are you going to make it into 1 ohm? What is the coil config on your sub? I would think d4 if you have it at 2 ohms? Which would mean you can only do 8 or 2 ohms with a single sub and if it is d2 you can do 4 or 1 ohm

no no it's a d2. I have it wired to 2 ohms but I want to wire it to 1. the p3s are d4s.

I stand corrected its at 4 ohms. my bad I misread the diagram I looked at for wiring.
Are you just running 1 coil right now? A d2 can only be 1 or 4 ohm if using both coils. Only 2 ohm load would be running only 1 of the coils

If it's D2, then you can only wire it at 1 ohm (parallel) or 4 ohms (series). D4 can only be wired at 2 ohms(parallel) or 8 ohms (series). You can also use a digital multimeter to check if you wired it correctly.
Drop it down to 1 ohm and set your amp for 1k of output and you should be ok.

how exactly would I do that? set it at 1k?

Wire the obsidian sub to 1 ohm then. You will be fine as long as you set your gains correctly. Use the DMM method

Dmm method with a test tone and a dmm (digital multi-meter)

here's a tutorial on how to set your gains

I got it all set up now I have a new problem. voltage stays 14-14.5 all the time. 2 12s at one ohm make my lights dim like they're hazards. I set the gains down a lot and it only made a difference at the point where I couldn't hear the bass... so I took one 12 out. running it 900rms at 2 ohms. used dmm for tuning. and I'm still having dimming. did I do something wrong? I got a quote from singer but it's gonna take me 2 or 3 months to get that money together so I'm trying to work around that for now

Be sure to see the sub specs. It should tell you the ideal sealed enclosure size.
