Hey all,
I am in a bit of a situation...
I have ordered two 4ohm DVC JL audio W3v2's, and plan to make them into separate home theatre subs.
But I have now been hit with the problem of power.. I have found the BASH 300w RMS @4ohm plate amp at a really good price and suite the JL's perfectly. However they are 4ohm DVC each...
Is there anyway I can wire each one to a 4ohm load so that I can get the 300w RMS? I heard about wiring just one voice coil but don't know of that would affect it negatively, does anyone know about this?
I really don't want to spend another $200 on amps just so I can get the BASH 500w for the 325w at 8ohms.
Please help me!
How about keeping the amp separate from the subwoofer cabinet and wiring the two drivers in parallel/series or series/parallel to drive both subs from the one single amplifier? You can make a small, attractive cabinet for the amplifier to use it as a stand-alone amp. This could also have the advantage of keeping the sub amp close to the mains amp, avoiding the potential for a ground-loop hum.
There is no way to wire a single 4 ohm DVC sub to get a 4 ohm load. It's not a good idea just running one coil either. You'd risk damaging the driver but would also be significantly reducing it's performance anyway. One option if you're set on that amp is to wire each sub's VC's in parallel (for a 2 ohm load) and then wire both subs together in series for a final 4 ohm load. You still be fairly limited overall because you be running two subs off of not much power. If those are your options though, go for it! 😃
Alright, thanks guys
I wanted to put seperate amps in them so I could sell them later on, but I spose it would just be easier to put them on a home amplifier and wire them to 2 ohms each. Thanks all!
Unless anyone knows of any 2 ohm plate amplifiers that make 300w rms for under $200 each
Or you could use both DVC speakers with one amp. Wire each speaker to itself in series (8ohm) then parallel to each other (4ohm). Then you can get a new sub (4ohm-SVC) for the other amp.
I don't see any issue with just using one coil of the sub. I see no reason anything would be damaged, or performance, except for power handling, to be compromised with just one coil used. Some t/s parameters may change slightly with one coil used vs two, but not very much.
Dual voice coils are really just for more impedance wiring options. They really serve no other purpose.
Ahh right, well I think I'll just go with a 2 channel home amplifier, but I can seem to find the right one!
Does anyone know of an amp that has 300RMS per channel @2 ohms?
I want it like this so it will be under 200w @8 ohms so I can run my big towers off them if I sell the subs.
Does anyone know an amp capable of that for under $400?
You do realize that you could use a 1000 watt amp if you wanted to, right? It won't instantly blow your speakers. Set up properly, it's actually much better to have more power than not enough. Anyways, the recommendation below is a good one. Also, if you get the DSP version, it has built in limiters that allow you to set how much power it makes.
And 1 more thing, does the Crown XLS1000 have the same ability to limit power or not?
