hey guys i was wondering how to remove the 8" speaker cover in the trunk of an 06 hhr and i was wondering what everyone put in there and what size amps and where you put the amp i want to put a sub there but will it fit thoughts???

 

If you use the search, lots of guys have done that here's one.

I installed a JBL-GTO804 along with a Crutchfield Sound Ordinance M1350. Sound is great for a single 8" sub it's a very powerful 8" sub, one of the best you can get but you won't be able to get the stock speaker grille back on because you need a 3/4" spacer to get it to sit inside the factory box.
