Hi Guys/Gals,

Hope you are all doing really well, i've decided to try a low freq box. Not too low though not sure how much battery power i will need. I upgraded my alternator to 300amp. Still running my HD8000 2ohm stable subs will be wired in series giving me a 2ohm load, two power 0 Gauge power cables coming from the alternator to the rear battery, two more power cables from the front battery to the rear battery, four positives to the amp fro the rear battery 1m lengths. The same goes for ground. Now I'm no guru thus I am posting and asking advise.

What do you think of the box. the box will fit into the trunk with the battery and amp mounted to the floor in the trunk, subs firing up with port firing up.
