hey wassup, i got a issue. i got 2 generic 12's which go for about 800 watts each with about 150-200 RMS each sub. anyways i powered em with a 840 amp generic as well. problem is that the subs dont hit at all i mean the trunk doesnt even vibrate. But i heard someone say that if you power em with a lower watt amp they will hit better. Can anyone confirm this?

 

Lower power amp.... no. Higher quality amp... prolly.

How do you have them wired? I would think you would want a two ohm load. Look in the sticky at the top of the A/V section and there's diagrams on how they should be wired up.

 

and higher quality subs. cheaper subs and amps over rate there power where better ones under rate there power

 

You probably just have the "cross-phased," meaning you have one of the + and - reversed. Switch one speakers wires and see if that helps.

If not, what kind of box do you have them in? Have you checked the gains on the amp?

 

also with that^ check the settings on the deck... when i worked in the shop and this happends its just usually little things like that
