Good audio shop in HI

Lost

I'm looking for a good professional audio shop in Hawaii to potentially do a full install on my Z. I have most of the equipment from my previous car already (Head unit, 2 12" Rockford Fosgates and amp, as well as a 4 channel for speakers). I can run wires and install most everything myself, though I would prefer to have it professionally done.

My biggest hurdle is the box(s) I would need to install them cleanly and without sacrificing my cargo area. Also wouldn't have the tools/hardware to add the rear speakers (have the base model) if there are no mounting brackets already there.

I have already looked at CustomBoxMan's boxes on ebay, but I would prefer something a bit lower profile and using both 12"s. Ideally between the seats and the crossbar and no higher than the cross bar, though that may not be possible.

Any help would be much appreciated, thanks!
