***FIRST*** I have a 15" fully loaded btl. the box its in is pretty big its 5 cubes. it has dual ports with sub and ports firing forward. i think the ports together is 80 sq inshes of port. the speaker is centered in the box with the ports on the ends of each side. just curious but would a box of the same size with a single port with sub in center or on the end with both firing forward be louder or the same. my video is posted on you tube and people are telling me it would be louder with a single port then dual.

***SECOND*** i am running mt btl with stock electrical alt, battery , and chitty 4 guage wire. no big 3. i have a ssl soundstorm 4000.1 mono amp. i have heard that chitty amps not only dont push your subs but can actually ruin it cause i think this amp sucks. i know i need a new one. how much of a difference will it make if i were to get all the electrical upgrades alt,big3, and battery's and a new amp. just wondering.

dont worry about the ports if its tuned right and has the right amount of port area it will be fine by switching to one port you may gain a tenth or two db's . as far as everything else you need big three and 1/0 power wire if you want any decent amount of power to go to that sub. if that amp can even put out any real power. after upgrading the wires look into a ho alt and a second battery then a good amp to power it like a saz 3000d then you will notice a huge difference in out put.

since that amp is so chitty according to the guy wit all the dumb ??'s I'm sure the guy that sold it to you would definately take it back. But for cheap cause it sucks
