i will say save more 200 and i will give u a decent 6.5 " comp set..why 6.5? cos it has more bass..since u dunwan to add amp or others, then u should at least get 6.5"..the bass is more solid and nice than 5.5...try it and u willl know

50w 4-5 ohm is mean the u need to use a spk at least 50w pmpo.....it match the cd player max output which is 50 pmpo

actually, if u dun plan to add an amp later, u can try those non-branded comp set..that wuit ur budget and use..

but if u wan a real sound upgrade, then the best way is to change to a better comp set first, then if got money just upgrade a amp..

using a 80rms comp set on ur hu wont sound bad,actually i tried using my 5750 to powerup Mb quart comp set..it sound damn nice...but of cos with an amp is ncicer,,,without amp,it just didn maximise the use on the comp set only.wont have any affect on hu and comp set.....
