Hey guys I'm new to car audio I have 4 planet audio 10 inch subwoofers and a vm audio 2200 watt amp and a Sony Cdx gt710hd head unit 52w per channel and the subs just don't hit like they should my buddy has 2 Memphis 12s and a 1000w amp and his hits harder than my 4 10s? Can anyone help me ? I tried adjusting all the settings in the radio and on the amp.. I also have a extra battery in the trunk and a soundstream 1000w capacitor.

 

What kinda "hit" are you lookin for? Thumpy or boomy?

It's either you need to change the box dimensions or you need to add a port(s) or passive radiator(s). Wattage means jack if you have the wrong enclosure setup.

Where are you from anyway?

 

it sounds like your enclosure is out of wack......

have one properly built and tuned...... those subs will hammer
