At the risk of sounding like a complete noob, im at 140-143 now on music, Im going to double the wattage, and add 50% more cubes.
Thats not enough to gain 7db? How much more do you think it would take?
Really appreciate all you guys help!!
it takes alot and the louder u get the more the car pushes back against the system. do u have any elecrical upgrades? what meter did u ger a 140- 143 on? someone explained it once. its like crushing a pop can with your hands. its real easy at first but the more u crush it the more it fights back
