subwoofer trouble

[zjltwins85 10+ year member]

Hey,

I just put a system into my car. I had 2 12' infinity refrences being powered by one Kicker kx300*2 amp. For a while I only had one of the refrences in, because the voice coil on the other sub was separating. One sub was fairly loud, but now that I have both subs in again, I can bearly hear/feel it. My dash speakers are the only thing putting out bass. If you know why the subs are no longer moving air at all, do you think you could help me out? Thanks

check all of you wires that could be your first problem if your not getting any sound from them........check them and lets us know.............

Check the phasing on the subs. Sounds like the pos and neg wires are reversed on one sub.

agreed, sounds like they are out of phase

How do I check the phasing?

Also i neglected to mention that I had replaced the defective sub, and now both subs are good. The subs are working, but unless the song is specifically designed for bass there doesn't seem to be much volume. When I only had one of the subs hooked up, i could feel it with my head unit on 25/50. But I can not feel anything now that I have hooked both subs up, I can not even feel them at all even at 35/50 or 40/50 for a regular rap song(The only songs where I can tell the subs do work are Bass explosion songs, or a woofer test. Even with these they aren't loud ).

thanks for your time

the phasing is the pos+ and neg- are hooked to the subs and amps make sure they are all correct because that is what usualy causes low bass volume in multi sub setups
