So i was wondering wat would give my subs more power. Say you have a 1000W amp, if u have 3 subs (dual 4 ohm) and u wire them as low as you can ull get 2.67 ohms would each sub get as much power as 4 subs off the same amp at 2 ohm. Wat im trying to get at is will 3 subs at 2.67 ohm get as much power as 4 subs at 2 ohm???. |

i'd assume 3 subs should get more than 4, being that the amp would put out slightly more power @ 2 ohms even, but then more of it gets split up between the subs. |

a 1000 watt amp at WHAT LOAD?
if you want to use 3 subs, go with dual 3 ohm coil subs or 6 ohm coil subs.
then you get an even 2 ohm load when you wire them up.
Use Ohm's Law and figure out the power per sub based on the output of the amp at the given load. |

If the amp does 1000 watts at 2 ohms:
and guessing it will do approximately 800 watts at 2.67 ohms:
Then,
4 subs at a 2 ohm total load will get 250 watts per sub, 1000 watts total.
3 subs at a 2.67 ohm total load will get ~250-275 watts per sub, ~800 watts total.
Note that numbers with the ~ are approximate since you don't know what the amp actually does at 2.67 ohms. |
