curious question for ohm loads

[HemiRT]

ok so i should probably already know this since ive had several audio systems but here it goes. ok so considering a new amp setup (i have an alpine m-1000 amp currently) i was thinking if there was another way to wire my subs to lower the ohm rating would i be able to get more power. right now i dont remember if i wired my subs, which are 2 type-r (2 ohm), in a parallel or series wiring. doing the math if it were in a parallel series id be at 1 ohm total. if it were in a series it would be 4 ohms total if i did that correct. so that means the wiring would make a world of difference in how much power i am supplying my subs. anyways so, if they were wired in a series and not parallel would my amp be able to handle that increase from say powering only 500 watts total to over 1000. i looked at m1000 ratings on the internet and it said "RMS Power Rating:

4 ohms: 600 watts x 1 chan.

2 ohms: 1000 watts x 1 chan."

this would mean that it actually puts out an overall rating of 2000 watts if wired in a certain way right (parallel w/ (2) 2 ohm subs)? could it handle that?

thanks

A pair of 2 ohm dvc subs can be wired to .5, 2 and 8 ohms...

I'll now provide this link (for the 10,000th time): http://www.the12volt.com/caraudio/woofer_configurations.asp

Study it. Remember it...

You amp is not 1 ohm stable. It provides 1,000 watts rms @ 2 ohms. If you want more power, buy a different amp...

speak english

2 dual 2 subs can be wired at .5 2 and 8

i was under the impression for parallel wiring it is (Speaker A x Speaker B)/(Speaker A + Speaker B) = total ohm rating. 2x2/2+2=1 ohm. Is that not possible to achieve?

http://www.hifisoundconnection.com/Shop/Control/fp/SFV/30046/view_page/Subwoofer_Wiring_Ohms_Law the top example of the second picture shows a 1 ohm rating of 2 dvc 2 ohm subs. i thought this wasnt possible as you said. whats going on here?

thanks

are you going to believe a sales site or a manufacturer?

^ I coppied this from your post

the big thing about it is that you are giving off power ratings by 1 channel

like bridged ? or is your amp a mono ( only one center channel - no left or right )

because if its a 2 channel amp - and each channel gives 1000w @2ohm rms it is a beast of an amp.. lol

im 90% shure that the most power you can ever achieve from this amp is 1Kwatts @2 ohm load with propper electrical to back it up. running a 1 ohm load to this amp is mostlikely a bad idea also.

thats a mono block amp that i posted a quote about

depending on if it is a good amp that actually does rated you need to wire at 2 ohms and get 500 per sub

its a Hifonics BXi 2010D heres teh specs http://www.sonicelectronix.com/item_17654_Hifonics+BXi+2010D.html

from what ive seen hifonics amps are really good

RMS Power Rating:

4 ohms: 650 watts x 1 chan.

2 ohms: 1300 watts x 1 chan.

1 ohm: 2000 watts x 1 chan.

id have to imagine that the power ratings on the 2010 models are a little over rated but not by a ton. I realley liked my hifonics bxi 1206d when I had it.

you say ur subs are 2ohm coils ? are they single or dual ?

because if you have dual 2 coils then you can only wire to a 2 ohm load for your amp.

as I dont think it will take .5 load and last at all for music daily

but

if your subs are single voice coil 2 ohm then you can wire em down to 1 ohm load eazy as pie and recieve more power from your amp.
