2 4ohm dvc subs wired to 2ohm load

[stalephotograph]

is this possible? my friend bought a jl audio e1400d amp for his w7 and then realized it wasnt powerful enough for it. i told him i would buy it if i could actually use it. hers the specs: Rated Power:
240 W RMS x 1 @ 4 ohm (12.5V);
400 W RMS x 1 @ 2 ohm (12.5V)

but i read somewhere that it actuallyputs out 500x1 @ 2ohms. is it possible to wire 2 4ohm dvc subs into a 2ohm load? thanks to whoever helps.

If that is a mono block amplifier, no you can not wire it to 2 ohm, your only options are 1 and 4 ohm. If you were to get a 2-channel amplifier, then yes, you could wire them to 2 ohm each. And I don't think that amplifier is 1-ohm stable. I wired one of my friends JL subs to an Alpine amp at 1 ohm, but made sure he kept the gains down, and it's been running fine for the last three months. I wouldn't recommend it for you though. Hope this helped.

are the subs dual 4 ohms? or is the final load per sub 4 ohms (dual 2 ohm coils)?

Cuz you can do it if you have dual two ohm coils.

alright thanks ashaman, what you told me is exactly what i was thinking. every wiring diagram i seen on the net showed 1 and 4ohm but no 2, so i figuered id ask around. i guess ill keep looking around and eyeing the soundstream rubicon II 500watt and or the brutus 1500dx i believe it is which i can get 500wrmsx1 @ 4ohms bridged and if i upgrade later on thats one less i have to buy. and yes my subs are dual 4 ohm voice coils

Well what kind of subs do you own? If I knew their RMS power that would help some. The Brutus is a Mono block so it is imposible to bridge it, but I am not sure about the other amp, but I know soundstream is a good company. The Brutus' rated power is 1500x1 at 1 ohm, 1000x1 at 2 ohm, but I am not sure about 4 ohm. Your best bet is to get a 1 ohm stable mono amplifier and wire your DVC 4 ohm subs to 1 ohm. If you could give me the subs RMS, I could help pick out a qualified amplifier.

the subs are powerbass 12" chrome series, and are rated at 250rms a piece.

I don't know what your budget is, but I looked up the Rubicon you were talking about and it looks like a pretty good match for your subwoofers. Other options to consider are the PG 600.2 and the Diamond Audio D5 (I think it is D5). Basically any 2 channel amp that you can get 250x2 at 2 ohm or a mono block 500-600x1 at 1 ohm would be a decent choice. Update me on what you end up getting. Thanks.

ok i got a quick question. my cousin has a volfenhag ZX7170 4 channel amp for sale. the specs are:

1200 Watts Max Power @2 Ohms
600 Watts RMS Power @2 Ohms
250 Watts RMS Power @4 Ohms
2 OHM stable
Tri mode capable: 2, 3, or 4 channel
Dual Power Meters
Fan cooling system
Variable bass boost: 0 to 18 dB
Variable bass frequency: 30 to 100 Hz
Channel separation: >60dB
Signal to noise ratio: 97dB
THD: 0.03%
Frequency response: 20Hz to 20KHz
High and low level inputs
282mm x 59mm x 391mm.

ok my subs are rated 250rms a piece. would it be ok ro run this amp to my subs or would i be in danger of damaging them? he only wants $50 for it and it works fine. just let me know if its fine or if i would be headed for damaged subs. thanks.

That amplifier is OK for your subs, but in my opinion, the quality just really isnt there, in terms of sound and reliablity. My personal experience with that company hasn't been that great. I installed a similar model, but the 2-channel version, and it just didn't sound good at all. I hookep up my old school Orion amp to the exact same setup, and it sounds A LOT better. I really think you should just get a 500.1 Monoblock like that Rubicon. Are you planning on running any components with the subs, because this is a 4-channel amp? You can get that Volf for 150 shipped new on the internet. 50 dollars isn't bad, but I would much rather dedicate that amplifier to running speakers such as mids or 6x9's. If you want to go ahead and use the Volf, just bridge the amp and you should be alright. Hope this helped, and didn't confuse you even more.

alright thanks man. im having 2nd thougts on that amp now. i may just save and get the rubicon II 500watt for my subs. and im going to be getting some powerbass components here soon and thinking of getting the rubicon II 300watt to power them. i get this decisions that i want something and it can change in a split second that i dont. but thanks for the help so far.
