ask ko na din, magpapacustom oval speaker box na roof mounted, ala CRV-soundcruiser. which is more preferable among the 2?..para din maging parang "subs" ko na din yun...4 or 5 way co-ax na oval gagamitin ko...

add ko nalang din, anung materail, wood w/ felt, wood with fiberglass? or clear fiberglass?
