shouldnt my speaker wire have a smaller fuse than the amp? if i have a 200 amp fuse in my wire and 140 in my amp then the wire could let more than 140 amps through and would pop the amp fuses right?Knu's description breaks it down as clearly as possible.Their KLM 1/0 doesn't have the same current capacity as standard copper 1/0, but it is more than capable of supplying an amp with 2x70 AMP fuses.
You have to specify what size fuse you want -- If this is the only amp you'll be running with this kit you can go with the 150A. The 200A would cover you a 2nd medium sized component amp.
You meant power didn't you??shouldnt my speaker wire have a smaller fuse than the amp? if i have a 200 amp fuse in my wire and 140 in my amp then the wire could let more than 140 amps through and would pop the amp fuses right?

The fuse near the battery will have very little effect on what's happening at the amp. The amp will only draw what it needs, and your amp should never draw more than ~140A, and that would only happen momentarily at the peaks of the music signal, and it would only happen when you're running it at full volume.
The fuse up front is there to protect the wire (and your car) in case any portion of the wire down stream from the fuse gets shorted to the car's chassis.
If there is a current surge in the amp the onboard fuses should blow. The fuse up front couldn't be expected to protect the amp in that situation even if it were 140-150A.
