How big are the power and ground cables your using ?

 

[dadydolas 10+ year member]

so, why do you think you need a new amp? what is the problem

 

[Mass Car Audio 10+ year member]

I don't see why that amp won't power that sub. With 75a worth of fusing it should do around 600 watts bridged (estimate) drawing 75 amps worth of current at 12.8 volts.. Unless one or two of the fuses are dummy fuses and it's actually fused at 25a...lol

Do you have all the filters and the gain set on the amp properly ?

 

[ziggyping 10+ year member]

I have 8 gauge going to the capicator and 9 going to the amp (or vise versa) scosche brand lol, and what do you mean set properly? I have the bass bost lpf and gain almost turned all the way up. Do you think its the wireing?

 

[ziggyping 10+ year member]

And the proublem, is I don't think its as loud as it should be. I heard it at bestbuy and it was alot louder and sounded better.

So you have everything cranked to the max...lol

It could very easily be the wiring. Try switching around the speaker wires to see if that helps. Also what size is the ground wire ?

 

[ziggyping 10+ year member]

Yeah i pretty much have it cranked haha and I'll try that soon and the ground is 9 and 8 gauge too and its grounded to my seat post
