So.. I had one Alpine type R 15 (4 ohm dvc) in 4cuft box(32hz tune) on Hifonics brutus bxi6000d (2kw on 2ohm) with 0 gauge wire, 75a alt, 2x 55ah batteries and it was working like a charm.. subwoofer was moving 15-20mm in one way no smell and he was cool.. and now I put another Type R 15 so two alpines wired to 1 ohm (3kw on 1ohm) and subwoofers are not moving even 8mm in one way but getting hot.. do you know where could be problem? My lights are not dimming so I think electrical is good enoguh. what you think?
