alright you should be able to throw at least 1200rms at them. from what i'm seeing you have a 140 amp alternator so you should be fine running 1200.
eh kind of moving off mb quart since they discontinued a lot of their good quality/price amps.
soundqubed site is down right now for some reason but probably going to recommend one of their amps on this one since those are fairly expensive jl subs and need something a little better than mb quart.
so when soundqubed site is back up i'll link you their amp which should be in your price range.
you'll also need to upgrade a few wires on your car to make your electrical system more efficient.
you'll be upgrading your alternator to battery + wire, your battery - to body ground wire, your engine to body ground wire. you can either go out and measure your current wires(you'll need to google them if you can't figure out which one they are) or you can just get an excessive amount and cut it to whatever lengths your installer needs.

you'll also wanna figure out what gauge wiring kit you had installed. if its 8 gauge you'll want to replace it. if its 4 gauge it might be fine if its good quality wire. also can you go open the hood and tell me what number is on the fuse because just having that will give me an idea of what size wire it is.
