SOURCE: How to wire 2 ohm 2 12ich alpine type r's to box terminals?

Dual 4 ohm subwoofers can only be wired @ 1 ohm, 4 ohm or 8 ohm.
2 ohm mono load is not possible.
You will need to use (1) subwoofer to get the 1000W out of the amp.
Wire both positives on one sub to + on amplifier and both - on the same sub to - on amplifier to give the amplifier a 2 Ohm load.
Add a second amplifier, or buy an amplifier that is 1 ohm mono stable.
You can wire both to the amplifier at 4 ohms 600W, but they will share the power and only see 300W ea.

hi mat
you should have four terminals two plain and two with dots
to get the best power cut two inches off good speker wire
tear apart now place one wire from
plan black to red with white dot then
plain red to black with white dot
this is how set then up with my directed 1100d mono amp .. very loud at half gain
well hope this helps.............. ..benjaminsarmy..

SOURCE: How do i wire two 15 inch subs to 2 ohms

Hello familia_gome,

Those MOFO-15's have dual 1ω voice coils. So the only way you can get 2 of them to present a 2ω load is to use 1 voice coil on each one with the two of them wired in series. Using both voice coils, you can get a 1/4ω load by wiring the voice coils in parallel and then wiring the subs themselves in parallel. You'll get a 1ω load with the voice coils in series and then parallel the subs. Or you'll get a 4ω load with both the voice coils and the subs in series.

Here's a link to Power Acoustik's PDF for the MOFO's. I recommend that you check out the wiring diagrams on page 3.

Hope this helps.

John,
Checkout JL Audio's 8" subs I'll leave specs at the bottom, if you want to look around for something cheaper check out this install I did on a Jaguar X-Type. The sub here is a good example of a free air application and you can look for a sub with the same features. Keep in mind however this setup is using a high power Coustic 10" sub and you only need to handle the stock amp- 25 watts. So you may not need such a beefy sub, but something close would be good. If your sub uses a small enclosure go with something like the JL listed below. Good luck and let me know if you need anything else. -Dynami
