4 ohm or 1 ohm?

If everything else is the same, runing about 2kw to 2 15" L7s, would you go 4 ohm or 1 ohm and why?

4 ohms. doesn't make the amp work as hard to push that much power at a higher load.

It dosent really matter, as long as you have the power to give the subs at that load.

no problem running an amp made to run at 1ohm at that level. it will cost more to get that power at 4ohms.

See I asked this question but actualy plugged the amps in (a XX-Colossus 2 @ 4ohm or a XX-Herculese at 1 ohm) and all I got was people arguing about hifonics as a brand...

Less strain on the car's electrical system to run at a higher imp, even for the same power because the amp should be more efficient. Less current equals cooler running.

4ohm

go 4 ohms. more voltage, less current flow, will make run amp more relaxed. control over the subs will be better and so the resulting SQ will be.

and please do not use hifonics XX. i know the collossus XI and XX, the XI is rated with less power but will sound WAY better and WAY LOUDER. it is an analougus amp, will draw a lot of current and get pretty warm (well into 2ohms bridged). but is a rock solid amp with awesome SQ.

collossus XX is digital, will sound like a 1500watts analougus amp. power is nothing without control.

try to get a Soundstream VGA 1600.2. less current need than the collossus XI but same power and same nice SQ. i paid $350 back in the days for a brand new 1600.2 but they are not made anymore //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
