What odyssey battery do I need for this

[Gus]

I am relocating my battery to the boot to free up space under the bonnet.
I currently have a new bosch 063 battery which I could use but cant find and cages/cradles for it.
Was thinking about getting an odyssey battery but I dont know which one to get.
I have a few bits of audio equipment that will need to be powered too:
Alpine CDE 178 Power Output: 4 x 50W High Power Amplifier
with an Alpine KTP 445 powerpack amp 4 x 100W MAX / 4 x 45W RMS
also
2 x Alpine SWE 1200 underseat subs - Peak Power: 150W
The wattage is only what is advertised on the website and will probably be nowhere near as high as that.

Does anyone know where to get an 063 battery type cage or be able to recommend which of these odyssey batteries to choose.

I'd get a Varley battery as they seem to have more power than equivalent sized Odyssey.

Varley redtop 30 will see you right mate, or whatever the odyssey equivalent is to that. I'm on a redtop 25, but I have no fancy gizmos.
