right couple of pointers more speakers will not give you better sound quality.
filling the car full of amps wont achive anything either .
mounting speakers on wood wont help but whats around them does use dynamatt or a sound deadening product tape or foam all cables to stop rattling .
and if you must use wood use mdf its denser than chip or ply but illeagle in the usa because cutting it causes cancer if not using a mask .
for most cars the simple way to achive a really nice system is a pair of nice components in the front .a good not cheap head unit 1 x4 channel amp and one twelve inch sub in box .
a sealed box will make the bass punchy and tight but a ported box will allow the sub to flex moving lots of air creating more bass .bass is what they call in the business spl Sound presure Level .
in an audi id recomend a good headunit two amps one four channel to power two sets of components front and rear and a two or mono block amp to either power two or one twelve inch sub the box ( ported or sealed ) depends on the music you like listening two . this is a very simple system but will sound very effective .
if you like fast beats like garage or house then use sealed
if you like rnb ragga hip hop then id recoment a ported box so the bass drops to deep frequencys.
