I am looking for a place to mount a 300amp fuse and holder near the battery in the engine bay but there is not much space. Any ideas and pictures for reference?
cheers in advance.

 

I have seen members posts where they used a special built battery or a smaller AGM battery, that left a portion in the battery tray that might be used for additional electrical stuff. Then there are the members who moved the battery to the hatch area for whatever reason (weight distribution?). What are you adding to the car that would need close to 300 amps? If a stereo system, I have seen a dedicated POS/NEG brought to the hatch where they fed the system but never seen where they added any circuit protection at the battery (not my gig but that setup would have to be careful of a battery/car meltdown if any POS wire chaffing occurred). Interested in seeing what the end result is! Good luck!

There are four positions in the fuse box next to the battery, only three positions are used, use one of them.

 

 

Thanks for the reply's, i am putting 2 12" subs in the boot area with 2 1000w amps. one for the subs the other for 2 sets of component speakers front and back. the sub amp has 3 x 40amp fuses the other 2 x 40amp fuses the manual says add amounts together and add 50% so 120 +80 = 200 + 50% (100) = 300 amps..I know about the little fuse box near the battery but i have not seen that type of fuse up to 300 amps and my 0 awg cable is too big for it.so i want to mount a fuse holder near too the battery. worst place or my only option will be under the battery tray.

 

I believe those are "ANL" type fuses:

 

The alternative would be to mount a 300amp breaker and to that route - but my experience (in auto electronics since 1983) is to avoid breakers under the hood due to heat and the fact that things can get dirty, breakers are compromised by both of those.

Now, you COULD mount the breaker inside the ECU/RCM/BCM box, it would stay clean and cool(er) in there.
