if a amp says specs 4ohm 2ohm and 1ohm does it put more strain on the amp at 1 ohm

wondering if there would be a difference to the amp going from a 4ohm to say a 1ohm load

Yes it will create more heat and strain on the to run it at 1 ohm than 4. Mine puts out 1200w at 1,2 and 4 ohms. I will be running it at 4

if the amp is 1 ohm stable it will not put more strain on the amp.....

it will however put more strain on ur cars electrical

Doesn't matter if it's stable or not, it will put more "strain" on the amplifier running at lower impedance.

ok yea see i wanted to get a rockforte p2 sub enclosed but they are only 1 ohm lol

ok good to know the puch inclousers are only 1ohm so that stinks

also anyone know can 1 12 inch ported sub do just as good as 2 10 sealed subs

 

[its_bacon12 10+ year member]

Completely depends on the 12, the ported box, the 10s, the sealed box they're in, the power on tap and the car.

So, yes, and no.

see im looking at 2 5 channel amps one is a polk audio but it goes from a 4ohm to a 2 to 1ohm and a boston auc that is only 4 and 2 and Im stuck on the whole 1 ohm thing

Either one of those brands should have no problem running on a 1 Ohm load for subwoofers. Don't worry about it.

yea but only the polk says it can

what are the model numbers of each?

 

[mdsniper7 10+ year member]

boston is gta-1105 and the polk is a pa d5000.5

Fyi ohms= resistance... Im not 100% on this but I would think higher ohm load = less power which in turn the amp struggles less. Lower ohm load= more power going through which in turn means more heat and harder on internals. Now just because an amp is rated for 1ohm does not mean it runs better at 1 compared to 4. simple test is to hook a sub up at 1 ohm, blast it for a while. Feel how warm the amp is. Now do the same at 4 ohm and I bet you feel a big difference.

Any amp worth it's salt will not be affected by the load it's ran at (provided it's within manufacturer specs)
