I was wondering how to get 2 ohms out of a dual 2ohm sub? The brahma says you can wire it for 1/2/4ohms. I would like to get 2 ohms out of each sub and the run them parallel for 1 ohm. Angel ------------- BOOM, BOOM, BOOM BOOM....

You can't. The Adire site is giving possible impedances for multiple subs. If you have two 2 ohm DVC's, wire them each in series for 4 ohms, then parallel for a 2 ohm load on the amp. ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Thanks Steve I couldn't think of any way that it was possible. ------------- BOOM, BOOM, BOOM BOOM....

Actually, it CAN be done with a single driver. If the VCs are wired in series, that gives you one 4 ohm load. If you wire the VCs, one to each channel of a STEREO amp, that presents a 2 ohm load, and if you wire the VCs in parallel, that will give you one 1 ohm option.
------------- It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I have only one 1200.1 mono amp right now. When I get the second amp I will be wiring each sub for 1 ohm. I was just confused about the brahma website saying you could wire the dual 2 ohm sub for 1/2/4 ohms. But thats not what the website means as explained to me by Stevedart above. >Actually, it CAN be done with a single driver. If the VCs are wired in series, that gives you one 4 ohm load.

And when you do get a second amp You'll be using a distroblock with a crossover right? The amp will be a mono amp i assume? or how are you going to split the RCA and Remote wire? Do you have a diagram or can you explain how you will run the wire. Because i could not think of any way .

The second amp will be an identical 1200.1 mono kicker. I could use the amp strapping circuit to connect them both together, but I will probably run each seperately to be in stereo. For dist block, I don't need it because I have 2 runs of 0/1 ga and a run of 8ga for my 300.4 that runs my mids and tweets. I will be adding another run of 0/1ga for full length ground to lower resistance. For RCA I have 3 RCA's running to rear Front/Rear/Sub and the Kicker has a preamp output to jump a short RCA to the second 1200.1. Remote wire will have a relay since I will have 3 amps instead of 2. It would probably work without, but I'd rather do it right. For Crossover, I always use amps onboard x-overs. Works fine for me. Here is what it looks like now: ------------- BOOM, BOOM, BOOM BOOM....
