How can i wire one 2 ohm dvc subwoofer to a mono amp and make it run at 2 ohms?

Question

i bought a new amp thats 1800 watts max and 900 watts rms at 2 ohms, and 900 max watts and 500 watts rms at 4 ohms. my subwoofer is 800 watts rms and 1600 watts max, the subwoofer is dual voice coil and 2 or 8 ohm. the box says 2 OR 8 ohm.

the problem is i can't find a wiring diagram that will tell me how to wire this dvc 2 ohm subwoofer to a mono amp and have it run at 2 ohms so i can get the full 900 rms watts out of the amp. the only diagrams i cam seem to find run a 4 ohm load to the amp.

Answer 1

there is no way you can get a final load of 2 ohms with a subwoofer that has dual 2 ohm voice coils.

the only ohm loads you can get will be either 1 ohm, or 4 ohm.

that site shows the only wiring options for one 2 ohm dvc sub.

if you have two of those subs, then yes.. u can get a final 2 ohm load. but its impossible having that load with just one amp and one sub.

Answer 3

You could use one coil, that would give you 2 ohms but you will be losing alot of output from the subwoofer as opposed to having both coils operating.  If you have one 2 ohm dvc sub you can either wire it in parallel to get 1 ohm or in series to get 4 ohms.  Get an amp that is 1 ohm stable.
