Can I solder directly to a terminal?

I just got my subwoofer and plate amplifier in the mail today. I didn't realize the plate amplifier would have terminals on the end, and the subwoofer just needs speaker wire. Can I just solder the speaker wire onto the terminals, or should I snip the wires, and solder them directly?

The amplifier board is Dayton Audio SPA300-D 300W
Subwoofer is Dayton Audio UM10-22 10"

I hadn't given that any thought tbh 🙂 Would soldering to the terminals void the warranty? I would have thought not for both cases, but I suppose the detail is in the small print.

I would just snip the terminals off and be done with it. Another solder free option is for you to make up a short lead with appropriate terminals to mate to what you have.
 
Not sure exactly what the connections from the plate amp are from the pic, but you should be able to find the mating connector from home depot or another HW store. Make a little jumper to test everything to make sure it works. In a pinch, you can crimp with vice grips if you don't have a crimper to make the jumper. After you're done, pull the wire and connector in opposite directions to make sure the crimp is good.

Then do as Mooly suggested, cut off the ends and strip the wire to eliminate a connection. Or not, not sure if it would matter in a sub.

Why would you solder that? Cut the spades off, strip the wires, and put it under the screw. Push it down, stick in the hole? They are spring loaded terminals... What am I missing?
 
I suggest contacting Parts Express to see what exactly the warranty terms are.

You may be able to slide the heat shrink back and just insert the spade terminals directly into the terminals on the driver. That should be good enough for a quick prototype test until Parts Express responds to your warranty question.
