whats the coil config? maybe you have it wired wrong?

 

[BallinByNature 10+ year member]

the sub is dual 2 its wired to 4

i would start by getting a amp that will handle a 1ohm load...

What is the box made of?

What power wire is feeding the amp?

Gain settings?

Crossover settings on the HU and amp?

Try sealing the port with some foam rubber, or similar, to see if the problem is the port calculations.

power:2ga rf from batt to dist. block then 4ga knu to amp

gain:i set it with my dmm its not even half way

crossovern amp about 70-80hz/hu i have my lp filter off and my hp filter on 125hz

That amp should give you 500 watts at 4 ohm bridged. Pushing a 15" sub that should pound pretty good.

Are you saying it's not loud in the car or are you trying to do hair tricks and impress people blocks away?

That all sounds correct.

hu i have my lp filter off and my hp filter on 125hz

That sounds like your main speaker outputs, not the sub out. That would be wrong for a sub out. Your sub out should be set at around 80 hz LPF, not HPF. Double check you didn't set it to something wierd like 30 hz.

i have my sub vol on 2/10 on my HU

I'm having trouble with the forum.

Check to make sure the sub outs are not set to HPF. The sub out should be LPF at around 80 hz. Not the main speaker outs. They should have different settings. Main front could be HPF at 80 -100 hz.

Turn the sub out volume up to 7/10.

my amp is on lp@about 80hz

if i turn to 7 it wont clip my signal will it

how much port area? and is the box strong and well sealed? voltage drop?

If it does then you set your gains wrong. It should have been set at 7/10 (70%) when you set your gains.

Try it first, see if it gets louder.
