I am using a infinity perfect 10.1 sub with a cheap performance teknique amp

the amp is bridged

problem is that when the amp gets turned up above half way right now the speaker starts to get real distorted

also I can sometime hear something that sounds like a rattle or like a quick hit to a solid object come from the box



could it just be a ****ty box
a box that is too large or what

it does it on any amp I have tried



the box is about 14l*14w*6depth on top with 8"depth on bottom



what gives?

 

also does anyone have the stats on the 2chnl 200W+200W performance teknique amp?

 

what other amps have you tried? that is a pretty nice sub, so it might be the lower quality amps you are using. distortion causes that.

 

the other amp I can't remember the name

sad thing is it is in my friends car and his MTX cheapy bottom of the line sounds better then mine

 

i would suggest trying it out on a brandname amp that has at least 200watts. that will give you an idea if it is either the amp or the sub. good luck

 

well just put it on a rockford amp today

same thing


I dont think the speaker is blown though

is there a chance that the box is too large
I know the infinity perfect is supposed to be used on a small box but I don't know a lot about speakers yet as far as how much of a difference the box can make

and it is just some chitty walmart 20 box

 

the box will make or break your system.. do you know what size it is? if its off, spend 20 bucks on a sheet of 3/4" mdf, invest a couple hours time and you should hear a world of difference..

 

ok I don't have the right box size for the speaker anymore

does anyone have the right box size for the speaker

or can give me the right size to make each wall

thanks for all the help

 

you should have a box with 0.6 cubic feet of airspace..

 

ok now comes the question perfect square... of a tilted box like a typical hatchback desing


and does someone know the forumla for figuring out the volume of a triangle... I forgot it

 

for (at least thirdgen) hatchbacks, pointing the sub straight up will bounce the waves off the glass directly at you, which is a good thing.. as for the AREA of a triangle, its 1/2 * b * h, for volume you'd also need to multiply by depth...

 

hehe

me dumb



forgot it that simple

 

does the amp have a crossover built into it? My friends got the same problem.....turn it up load...and it distorts.
