You need to look at your wiring of the speakers and the Ohm rating on your speakers.
Below are the specs of the amp. You have the Tri-Way amp and the switch that controls
which way it configures it's output is critical. If you are powering just 2 speakers you set the
the Tri-Way to bridge only. Problem is, I cant find a manual. Legacy's site ( Manual Coming Soon.I say call them and ask for a manual to be emailed to you or mailed.

    it's shutting off for a reason. What speakers are you trying to run? Do you know what impedance they are wired for? Where is the gain set? When bridged that amp is only stable at 4 ohms mono and will/should shut down at impedances lower than that.

    Have you checked the fuses on the amp?

    Have you confirmed that you have both B+ and remote voltage at the amp?'

    When measuring the voltage, place the black meter probe on the ground terminal of the amp.

    That image just shows that you have chosen Auxiliary Input, can't see the red dots. Looks like you just need to reconfigure it.

    Tip & How-To about Watches

    Changing Watch Batteries
    Lots of posters ask "what is the battery in my (name of watch)" with a view to changing it yourself. This is a bad idea for many reasons. You don't have the tools or knowledge to remove a rotary screw on back, or the gasket sealant for a waterproof watch. Some fashion watches have 4 traditional screw and need professional grade jeweler screwdrivers. Also, there are about 20 batteries commonly used in watches, in various sizes and internal technology, Lithium Ion, Silver Oxide and Manganese Alkaline. If you buy them, you generally have to buy 10!

    Don't sweat the details. Just take the watch to your local jeweler. They have all the batteries at hand and the tools to remove the back. It is done whilst you wait for $8 to $15!

    There are lots of suggestions, specs and plans for loudspeaker enclosures available online with accompanying formulas for calculating sizes of boxes, ports, etc., but successful results tend to be achieved by experience as much as following plans and tuned port reflex enclosures are akin to the black arts - hifi purists would change the port size after a "bedding in" time for the enclosure and drive unit.

    Your subs are rated at 300 rms so clearly you are overloading them at 350/400 and you should be aiming to max them at around 250 in a reflex cabinet. If you really must drive them so hard you really need to consider an infinite baffle as an alternative enclosure.
