24 VDC 6A 145W Regulated Switching Power Supply
How to connect?
So this is my first time build. I'm trying to acquire all the needed parts, and of course a supply is a big one. I understand how to hook up the power (L,N,Ground), but how would I put this on an amplifier? And then consequently, If I wanted to attach a external power switch or an LED light, how would I attach thouse as well? What are the COM and V+ connections?
The answer to all of your questions is "It depends"......on how professional and fool-proof you want your final product to be. I can tell by your questions that you are VERY new to this. If you want the cheapest fastest and ugliest design - you just get a piece of plywood about 18" by 12" and nail or screw all the parts (pwr supply and amplifier modules) to it. All the wiring shows and little kids should never be allowed to touch it EVER. If you don't want to do that - you willl need to either buy a chassis box or rip all the guts out of an old receiver to use it and the switches, power cord and speaker terminals.Regarding the COM and V+ connections - if you do not know what they are for yet - you do not have enough knowledge (yet) to build anything. They are the SINGLE ENDED power output for the amp modules - and if you do not know what that means - there is a 50/50 chance that this power supply will not work wth the amp modules you may buy. You need to either do a lot more reading about this OR buy a complete kit (amp modules, power supply, chassis). Don't worry - this is how I started.....many years ago.....you learn a bit with each project. If I were you and did not want to waste money blowing up stuff to learn what not to do - I would buy a kit figured out by Parts Express.

Hi, can i power 2 2x50W amps with this. Im no expert (yet) and it looks like theres 2 power outputs.
Yes it would.

Can it be used to power the 1A Bluetooth Receiver?
I am using this power supply to power one of the Sure Amps. Working great. I would like to add the BT-1A Bluetooth Receiver Module, to the current setup that I am using. The question is can I power the 1A Bluetooth Receiver from this power supply? What would I need to do to do so? Is it as simple as cutting off the USB off and connecting to the power supply output? Or would this just burn it out?
Since USB cords have several wires for power & data transfer, you will need to identify the proper wires for power and then connect to the terminal strip.

Can this be powered with a dc to ac converter?
um, why?Shouldn't you be using a DC:DC converter for that? It's a bit beyond silly to convert power twice, you loose at least 10% each time you do it...

Can I use this PSU to charge 2 12V SLA Batteries?
I realize SLA batteries need some sort of monitor, could I put some sort of monitor in between this PSU and the batteries? a series of resistors?
There is alot more needed then just some series resistors to properly charge SLA batteries. Charging current should not exceed C/3 (1/3 capacity of battery), so for those 5Ah batteries you listed the charging current should be less then 1.6A, and lower charge rates are better for battery health. This power supply can produce currents far exeeding what the batteries can handle.For SLA batteries maximum charge voltage is also a concern as the resistors will not limit the voltage. The maximum voltage a SLA battery should reach under full charge is 14-14.4V depending on the type of charge (shunt vs PWM/linear). The voltage may not be a problem with this regulated supply if you have batteries in series, as it may not even produce enough voltage to fully charge the batteries when in series. Depending on the no load voltage of the power supply (if right around 24-25v) you may not even get past a 20% state of charge, very bad for the health of any type of LA battery.

can i use two of these and wire the output in series to get 48VDC?
I would say "yes" with 98% certainty. From looking at the zoom pic of the barrier strip terminals - it looks like the system Ground is separate from the COMMON terminals - indicating that the output V+ and V- are "floating" from ground. This is the most common design for switch mode pwr suppliers. If you want to avoid risk - measure the resistance from COM to GND terminals. If very high (over 1K ohm) then you are safe to wire them up this way. Make sure you turn them both on at same time - ie a single switch to pwr up as if one is "off" while the other is on - not sure what will happen if you have a load connects.
