would i gain or loose output ??

ya im thinking at this point its my music ( tablet ) i need to test my music and see if it is clipping as im thinking it is.

when i was smelling my sub i was playing a new song i just downloaded to my table so im thinking thats my main problem.

as iv had this amp on this sub for about a month to 1-1/2 months and have had no problem.

and i am going to set it down the gain so i dont blow it for good. i cant afford that right now and im going to try the sub inverted and going to turn my box so the sub is up and port is back.

what sub would be good for this box and my ppi 7000 amp ? as im thinking of going with something that can handle more power. but im not rich so something like under $300 . maybe a sub rated around 2500rms. i want d2 .

as im getting to the point of wanting more, more bass,, more db's .

and im still when its all said and dont im going to have 2- 15" in this truck.

I have tested all the sq subs in the hdc3 and hdc4 subs series and they all do not like being tuned under 38hz.

Many do it anyways and will notice it bottoms out if you play tunes for to long on certain notes.
