isnt this conception correct

[bcleachd]

if i have one l7 12'' hooked to one pg x1200.1, 1-4 ohm stable with a rms rating of 1211. Plus the box will be 3.0 cu. ft. ported and my question is wont that box make it less a strain on my electrical to produce spl at low volumes from that sub?

Plus What watts rms should i play this with my amp the way it is stay safe and stay at 750 or go a little higher?

Is that 1211w rating @ a 1 Ohm load?

Does that amp output the same wattage at all impedence loads similar to the JL slash-series amps?

And what VC configuration is that L7?

 

[bcleachd]

the amp is 1211 at 1-4 ohms rms and the sub is 4 ohm impendence

Well the larger the box the is,the less power it will need to produce the same amout of spl,I would dunno if it make a diffenece or not if the lower the ohm the less current u will pull,but I would think so,so wire it in parrallel/series...a 4 ohm load and just set the gains correct and u should be fine,u say u have a yellow top...do the big three and u should be fine

Box has nothing to do with strain on electrical system, amp and amp settings do. Also, i done beleive that amp is regulated so it produces 1200w@ 1ohm Nominal, probably 600@ 2 and 300@ 4 though some amps may have power suply limitations and be able to produce more than 600 and 300 simply because the limiting factor is current draw and not rail voltage.

The larger box needs less power soo....less power means less current DICK

The Xenons will have a stable output voltage from 1 to 4 ohms; he's correct about that.

A ported box will allow you to get a similar amount of output for less given power, so in that respect - yes, it would be less of a strain on your electrical system.

Wow, I didnt know i was comming off as a dick...well i geuss some people here on CA need to grow up. Now i will restate what i said... Enclsorue has nothing to do with electrical strain, amp and amp settings do.

There was no reference to "at a given volume"

Also, if you get too large you loose output //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

If the driver is capeable mechanically and thermally then a larger enclosure (in the perspective i am speaking from) is LOUDER.

I didnt know that amp was regulated. In that case, if you are worried about electrical strain run it at w/e impeadance the amp is most efficet at. Say it is a D2 driver if it is more efficnet at 4ohm it would make more sence to run it at 4 ohm if it is mroe efficent at 1 ohm you should run it at 1 ohm.

but my amp is rms 1211 at all ohms 1-4

I get that now, i didnt know it was regulated. Because it is you need to find out efficencies (current draw) at a given Impeadance. If you can, run the amp at its most efficent impeadance for least electrical strain.
