Anonymous | you MUST be young cause you DO NOT know much about car audio I'm a MECP certified installer and been that way for 9 years i think i have learned somethings after all those years. and i think that GlassWolf shares the same opinion about audiobahn and he is a MECP installer too for over 10 years so you may want to listen to someone that knows a little more then you. |

In my opinion i would sell the subs and get some adires...but its your choice. |

Those subs may already be reaching their mechanical Xmax, or in other words, extending as far as they can at full output on the present amplifier. The "power handling" rating of a speaker in no way means that this much power is required for peak performance. The rating is simply a thermal measure of how much heat the voice coils can tolerate without damage. Remember, a speaker is a coil of wire wrapped around a tube, inside of a magnet, all of which is attached to the cone. as electricity is sent through that wire coil, within the magnet, heat is generated. The more power sent to teh speaker, the more heat it generates. This becomes even more the case if the amp clips, sending DC voltage to the speaker, in which case the coil becomes a heating element, and quickly starts to cook itself. Anyway, my point is this: if you want a louder system, you may be better off adding two more 12" subs and another amp, or, going to subs with either a better Xmax rating, or more surface area.. or both. just as a general rule of thumb: adding a second sub adds +3dB doubling the power adds +3dB +1-dB is an audible doubing of volume, which also translates to an increase of power by a factor of ten. 2x volume = 10x power |
