basically your sound system settup can be as nice as much as your willing to spend on it.
basically if you know what your doing u can make a sound system play and sound nice with out having to hit your pocked to hard.. you got to think about who are you intending to play music for, are you going to listen to this music for your self while your driving or you are planing to show off with a decibel drag settup.. if you are looking for competition speakers thats a completely different settup from somewhat audiophile touch.
if you decided that you dont want to add to much weight to your car and you just want to have a nice quality sound system then you might need the following.
you want to buy a component speakers to replace the existing factory drivers and tweeters, with the following brands:
- boston acustics ( very high quality / high price )
- focal audio ( very high quality / high price )
- zapco ( some crazy quality sh!t )
- MB Quarts ( high quality / high price )
- cervin vega ( good quality for a good price )
im sure there is plenty more but these would be my top best picks.
now if you want a subwoofer you can buy this nice subwoofer kit from BSW, but what i plan on doing is to build my own sub enclosure and put one of the following drivers in there:
- RE audio - ( i specifically to buy the slim sub they make to save on weight and size, but i have installed in the past a 12" XXX which was powered by a 3000 watt RMS amp and that was extremely loud with awesome quality.. )
- Adire audio bramah ( i seen this sub brake the door hinge of cars from the base)
- zapco ( good sh!t )
there is plenty of good not so mainstream brands that make good subwoofers but i guess thats for u to explore
now to power all these speakers u need a amp, i plan on using the factory amp for the component speakers, but u might decide to run these from a seperate amp then u will need a 4 channel amp, as for the subwoofer your looking to find a mono channel amp,
brands that i have had experience with and i know they make good amps:
- zapco
- HiFonics
- sound stream
- phenix gold
- orion
and if you are looking to run a high power system u might need additional power source so your light don't dim out the best solution for this is to get a Batcap model 400 made by Xtatic,

regular cylindric type capacitors are just expensive and in-efficient with the power storage.
good luck with your system if you do decide to do some crazy sh!t make sure all your hardware is secured and u might want to consider sound proofing the car using dynomat.
