wire it in parallel and it will presant a 1 ohm load and youll get the most out of your kenwoodps811d amp.

so if i wire 2 subs like that 1 on each channel of my amp it will be 1ohm.

thanks morgan

some one say if i am wrong.. if my amp is mono but has 2 channel outputs and is 1ohm stable then it means both + and both - of each channel are joined together in the amp so if i run 1 dual coil sub like this http://www.crutchfieldadvisor.com/learningcenter/car/subwoofers_wiring.html?subs =2&impedance=DVC2x2 to a + and - on my amp, and the other sub to the other + and - on my amp, that would be 0.5ohm on each sub so my amp will be runin at 1ohm.
sounds good to me ????

I assume that amp is 1 ohm stable with both channels. Which means that you can go pass 2 0hms on each channel. So, what I would do is wire 1 voice coil to a channel (1 voice coil on 1 sub to a channel). That would present a 1 ohm load to the amp. Mono means both channels act as 1 as far as it goes with the ohm load. Which means you cant go pass 2 ohms on each channel.

if i put 1 voice coil to 1 channel that would only be 2ohm as each coil is 2 ohm each.
also i know both voice coils must be wired up on each sub. ??

i have them both on the amp at the moment at 2ohms and they soung great but would be better if i could get them on at 1 ohm ? i think ?

Wire it like option 2 in the pics (2Ohms). Option 1 will over-heat because it's .5 Ohms. At 2 Ohms you wont be getting the most out of your amp, but it's better then running it 8 Ohms. There is now way of wiring those subs together at 1 Ohm. If you were useing 1 sub you could.

O, I was thinking you had a mono amp. If you don't bridge it you can run 1 sub in each channel at 1 Ohm. Wire each sub like option 1 (1 sub to each speaker output).

It is a mono amp so best to wire them at 2 ohms then
