my sub just anit loud

[hotbodkev]

I have new 5000 watt Mono Class D amp and a new 2000 Watt rms sub. The sub just does not sound like 2000 watts. The sub sounds more like 500-700 watts. I do a lot of work of systems but cant figure out why the sub does not sound loud. Any pointers

box? sub? amp? setting on everything? power isnt the greatest way to decide how loud something will be //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Also asking these ?s, I will promise you are running no where near 5k watts

I got the box set as close to the golden ratio that I could get it. I messed with all the settings max out the gain and still cant get it that loud. It still sounds like 600 watts Its 5000 max 2800 Rms. even on off brands they still will put off near the wattage

4 guage wire you're running a hell of a fire risk if you're trying to run 5000 watts through it.

start searching and reading is what I recommend //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Yeah the ground wire was smokeing. But I thought 4 would beable to handel 2000 Rms

I tryed searching but dont no of any good sites cause I learn from what I do. So I kind of teach my self

Did you wire the sub right? It might be 2800rms @1ohm, but if you wired it parallel to 4 ohms, you probably are getting less than 1000 watts (We dont know what amp you have).

Thanks for the site

Yes I wired it 2 ohm so i should be getting 2000 Rms from amp to sub. Sub handels 2000 Rms

I have never done this before but the largest wire that I have is 2. the size that I have on there is 4 (which I was thinking was to small) but would it be safe to also hook up my 2gauge wire on with the 4. I have alot of amp kits but that is that largest that I have right now and I dont have the money right now to go buy a larger size.

Whats your amps model # first of all?

 

[hotbodkev]

I think its PMA1200DA

I found the site http://www.alphasonik.com/frameset.html

On the back of my amp it says 2800 watt Rms not 2400 like the site

1st off, you running waay too small of a wire for that amount of power, i'd say bare minimum is 2 ga. 1ga or even 0ga would be recomended. the wire could be your problem, your not feeding the amp enough power so its not able to produce the power. now as far as maxing the gain, i definatly wouldnt do that. you could severely damage your sub doing that.
