the battery charger works i did 4 subs at the same time in my set up and i gained 6db on the meter it helps to keep your impedance rise under control the better the charge the louder it will be i found that you cant use an automatic charger on them it shuts off to soon and the higher the amperage (like 50 amp) the better the results.
