I have a boot setup similar to Liquids, 2 12'' subs witha side of the boot, takes up bugger all space, also have 2 amps sitting beside battery in that small space, have 6x9's in back parcell shelf wud never get rid of them! lol will make a better shelf outa mdf at some stage, also and 6.5'' splits in front they sweet not much bass tho. 6x9's arnt very hard to put in just pull out whole shelf fit em make sure u measure right so the magnet goes thru the gap when you put shelf back in. I have spacers in atm but will make a better shelf soon make it look more flashy lol
