Connecting multiple JST ph connectors

Hi,

I want to connect a peltier cooler that has four peltier elements and has four fans (that I think have two pin jst ph connectors. see image.) to a 12v power supply that just has simple clamping screw connections at the back (see image). The four peltier element will draw 30A of current at 12V, which is a lot so I‘m not sure about connecting them to some kind of bread board or whatever. The fans are also 12v, but hardly draw current.

I don‘t think I could get all eight wires into the screw connection even if snipped off the jst connectors.

What‘s the best way to wire/connect the power for this cooler?

Thanks!
