I would do a 300a just to be on the safe side....Im sure a 200a would work just fine tho

300a on all 3 of the fuses listed? wont the 4 gauge wire take smaller fuses? since the jl amp is only pushing out like 400 watts

that's good, i was just looking at sonicelectronics... they got some pretty cheap ones too. imo going with a fused distro block will be easier, and serve the same purpose as fusing all the power lines... your amps have on board fuses right?

300A for the battery, and 125A MAX for the 4-ga. You fuse to the wire, NOT the amp. UNLESS the amp has no internal fuses, than you fuse per the amp's RMS.

Well do amps usually come with internal fuses?

yes... you can see them, usually located next to the power,ground and speaker connections.
