Box help for jbl gti

[KristianJBL]

Hey!

Ive been looking on the net for awhile now trying to figure out a decent box and placement for my 2x 12" jbl gti´s powered by a jbl pdx 2200.1

So id like if any has some personal experience or maybe ideas for a great box with some good bass..

Also been talking whit alot of people and how the box should be placed in a sedan...Firing towards the lid and others say sealed off firing into backseats

The paticular car is a opel vectra B 97`

Thanks in advance!!
