tvcincy Posted April 29, 2012 Report Share Posted April 29, 2012 Hello, I just got my Crescendo BC2000d amp and hooked it up to my Kicker CVX dual 4 ohm voice coils. I think I have it at 1 ohm but I'm not sure. I had a PPI PC21400 that seemed to play them louder at 4 ohms. Here is what I have done: On the subs I have a wire going from positive to positive and negative to negative on both speakers. It's looks like an X on the back of the speakers magnet. From the amp, it had 4 terminals but I am only using two, a neg. and pos. I ran the negative wire from the amp to the negative terminal on the first speaker as well as the positive. Then I just took two wires and ran them from the positive on the first speaker terminal to the positive on the second speaker terminal. same with the negative. this should be parallel wiring right? 1 ohm? Then I took a multimeter to set the gain. i am running 14.8 stable but I used 2250 X 1ohm and took the square root. so I got 47.4 volts. I set the amp to this but the bass boost terminal says its clipping at this setting. I'm totally confused. I thought it would be waaaay louder. I'm thinking I did something wrong. Can anyone please help me? One guy said that amp should kill those CVX's and they weren't flexing like that Thanks Quote Link to comment Share on other sites More sharing options...
sps1989 Posted April 29, 2012 Report Share Posted April 29, 2012 (edited) if its 1 sub and is dual 4 like you say, then its wired to 2 ohms. which will give you about 1100 watts at most do you have 2 cvxs that you are trying to hook up together? or is it just one?

tvcincy Posted April 29, 2012 Author Report Share Posted April 29, 2012 Like this. yep, i looked there. that's how i have it. the black and red solid and the black and red dotted terminals should matter. they should all be connected together. i thought this amp would pound these speakers.

sps1989 Posted April 29, 2012 Report Share Posted April 29, 2012 it should be plenty for the subs. how did you set the voltage on the amp? test tone without speakers attached? Quote Link to comment Share on other sites More sharing options...
tvcincy Posted April 29, 2012 Author Report Share Posted April 29, 2012 it should be plenty for the subs. how did you set the voltage on the amp? test tone without speakers attached? yes, i used a cd quality test tone at 40htz -5db. Turned hu up to 30/40 and then set gain. i set to 48 volts but it reads it's clipping like crazy. i had to turn down to 38 volts. if i have them wired correctly at 1 ohm, that's roughly 1500 watts. i don't know whats going on man Quote Link to comment Share on other sites More sharing options...
sps1989 Posted April 29, 2012 Report Share Posted April 29, 2012 which head unit do you have? may try to turn the volume down some and try again. and are you using 1/0 wire? Quote Link to comment Share on other sites More sharing options...
skittlesRgood Posted April 29, 2012 Report Share Posted April 29, 2012 what are the EQ settings at the HU set to? are you using bass boost? what are your filters set to on the amp?

Have the LPF to about 125htz. subsonic i didn't touch and phase setting i didn't touch. i just took an ohm reading and i do have them wired at 1 ohm. the multimeter read exatcly 1. so that narrows problem down.
