specs on mine..
jvx avx820 with laptop hdd and av connections in cubby
alpine mrp 400 amp under glove box (you can even open the glove boxn still not see it)
vibe space 8 behind the bose grille
sounds pretty decent although not really enough bass from 8 but not bad overall sound considering its still sing the bose amp for main sound.
best stealth instal ive seen/heard is Rob/H5 the only visble bit is the sub in th eboot and mean I only the sub as the instlal has avery clever use of boot space for the box , tweeters are hidden , amps hidden great instal.
