4ohm Sub 2ohm amp?

Question

ok i have a kenwood 4ohm (single) voice coil 12" sub and a kenwood amp that is 4ohm and 2ohm and 1ohm capable here are the amp specs 300 Watts x1 @ 4ohms, 600 Watts x1 at 2ohm RMS and over 600watts at 1 ohm i just want to hook it up 4ohm sub 2 ohm amp make sense???

Answer 1

If your amp is 2 ohm stable then that means it can handle 2 ohms and higher.  So running it at 4 ohms is fine to do.  As long as you are not running it lower then 2 ohms then you are okay.

The advantage of running it at a higher impedance is that your amp will create less heat and distortion.  It will also be more efficient.  The trade-off is that it will produce let power.  As with your amp, it will create 300w @ 4 ohms and 600w @ 2 ohms.  So if you hook up your sub to that amp then you will get 300watts to your sub.

Wire it up like in the link below.

Good Luck!!!

Edit: Don't look at max or peak value, only RMS values.  To get the most out of your sub you will want to match the RMS value of the sub to the RMS value of the amp @ 4 ohms.  So if you sub is 500w RMS then get an amp that is 500w RMS @ 4 ohms.  If you get an amp that is over the RMS power of the sub you can risk damaging the sub.
