Hello aj_vidal22,

Here's the link to MTX's sub page where you can view or download the information you need to properly wire the subs to your amp.

For maximum power, you'll need to wire the subs so that they present a 2 ohm load to the sub outputs on your amp. That will give you the full 420 watts RMS the amp is rated for. Likewise, you,ll want the run the front 4-channels at 2 ohms. Run separately, they produce 85 Watts times 4 channels, or if bridged, 130 watts times 2-channels. But if you run fronts at 4 ohms, they only produce 70 watts times 4 channels and your sub output at 4 ohms drops to 210 watts.

Hope this helps.
