I have 2 15" kicker cvx's 2ohm. Earthquake phd5000. I have the subs wired in series for the 2ohm load on the amp. Well, when I turned it on there was very quiet distorted bass. You could barely tell they were even on. I went through all my settings on the radio and I kept the gain around half way on the amp while messing with the hertz. I can unplug one sub and the one that is still hooked up pounds like crazy. So I unhooked it and hooked the other sub up and it pounds by itself. Do you think that my charging system just isn't strong enough for that amp? I have a ford expedition with a factory alt. which is 150 amps and a red top optima battery. 2 gauge wire run through with 10 gauge speaker wire on subs. What do you think I will need to power it up correctly? Would a 200 amp alt make a difference? Extra battery? Any help will be appreciated.
Run both subs in series then connect them togethor in parallel. If they are working fine by thereself your deff connecting them with reverse polarity.....(+\- backwards somwhere)
