I need a port box for 2 12 and a 3000 watt amp
 

i need a ported box for the back of a s10 extended cab 1 type r 12 and a powerbass 2xl 12

you want to use two different subs in the box?

mixing subs = not cool

why not
 

why not 2 subs in a box

2 subs of the same company, model, and size.... sure its great.
2 subs of different companies and models... not the greatest idea.

what about a box for the power bass 2xl ported with slot
 

i have the program to calculate it but i just dont get it any help

its not a good idea to use two different brands of subs in one box!

No youre amp will see a very odd load, also when building a box you have to factor in many mechanical characteristics, and mixing more then one of different subs youre enclosure will never perform good 90% of the time. For what you want i say keep the amp and sell one of the subs and buy one to match then other. No one will help you in the situation you are in due to the fact of it being inpractical.

if you REALLY want to make an enclosure for these subs, put them each in there own sealed enclosure. 1 cubic foot each should do the job.
