AMP Impedance Load

Hello :

I've a 1000 RMS rockford amp, and have 2 rockford p3 12" subs each is dual voice coil and each coil is 4 Ohm.


At the moment the subs are wired in parallel , the Ohm load is 1 Ohm to the amp.

Now ive read up in the manual says i can go to 0.5 Ohm load with this amp .


Will it make any diference from 1 Ohm stable to 0.5 Ohm ?



Thanks.

for the most part the lesser load the amp 'sees' the more power it can put out, so if you could get your to subs to load the amp at 0.5 ohms (which you can't) then they would receive more power. if you got different subs that loaded the amp at 0.5 ohms the amp would dish out most power.

I don't think I could have put it any better myself.

Lower impedance load on an amplifier means a greater power output. I've never seen a rockford amp that is stable that low. Impressive.

I bet the amplifier says .5 ohm stereo or the same as 1 ohm mono, that is if it is a 2 channel amplifier.

The reason an amplifier makes more power at a lower resistance is exactly that, lower resistance trying to stop the power from flowing.

im amazed u could get 3 dual 4 ohm subs down to 1 ohm....i just cant understand that

and you wont get er down to .5 either im pretty sure

but hey, ive been wrong many many times before

I'd be curious to see which Rockford amp says it is .5 ohm stable? Perhaps it is .5 ohm stereo.
