It's a volvo 850 t5-r -94

looking for

(those will go on head unit) 4x 50W rms
2x 5,25 in front door
2x treble (<-- just quick translate) the high hz speakers ) (or do they have to be powerd by amp?)

will go for an 2 channel amp for those depends on what the rms watt will be on
2x 6x9 (on the rear shelf/ledge)

a 12" sub or maybe 2x 10" if they can be powerd by a 'cheap" amp

im up for all opinions and suggestions i can get

i have 500-600$ for this stuffs if it will be enough

are you in the us?
you're head unit is probably 50 watt peak. it will be around 20watt rms. thats usually what head units are rated at but if you want to be sure just look up your model number and ignore anything that isn't rms watts.

so you are running 2 speakers off the head unit and 2 off a 2 channel? why not just get a 4 channel? the price difference is minor.

so you are wanting component tweeters/midwoofer or coaxials? here are examples of each:
coaxial : http://www.sonicelectronix.com/item_18902_Infinity-Reference-5032cf.html
component: http://www.sonicelectronix.com/item_18912_Infinity-Reference-5030cs.html

on to the sub...on a budget you'll want to invest in 1 sub because it will simply save time, space, quality issues.

i'd also suggest not mixing the sizes or using oval speakers at all...round is the way to go and doing 2 matching sets makes sure they perform well together.

im not in the states actually got a budget of 800-900$ but the prices are so huge difference between us and eu

so i put all 4 speakersi n front to a 4 chan amp instead of running them from head unit?

is there a cheap amp to power a 10/12 " sub +2x 6.5 speakers ?

component tweeters/midwoofer or coaxials?

which are recommended if im not aiming for bass (want the sub in the back to handle the litte of bass i need)

your midwoofer plays completely different frequencies than your sub will so the bass it plays is still necessary.

components are better all around except you'll need to do a bit of extra work mounting a tweeter. also those component speakers are powered by 1 amp channel each not 2 per. so 4 sets of components still only requires a 4 channel amp.

trying to put a sub and set of speakers on the same amp is a bad idea. the power ratings are low and they and d class amps are more efficient.

so you'll want:
4 channel amp for your interior speakers
monoblock amp for your sub

tbh i'm not really sure what the shipping cost would be if you order from the us so it kind of screws with me picking stuff out for you. happen to know if you have any hertz audio dealers in your area? they make good stuff and its easy to find a dealer in europe i think.

also just noticed the bold part.

if your fronts are 5.25 i'd do 5.25 all around with 4 of the same speaker. this ensures that they all sound the same.

Yeah we have pretty much all the choices us hasbut its 2x cost on most

hertz is one of the cheaper

I got slots for 2x6,5"
4x 5,25
2x4"

Are there tweeters on 4" from hertz

would be easier to just find a local dealer and have them set you up since i'm not familiar with the exact specs on a lot of their stuff.

if you don't want a lot of bass just get a single 10 inch with like 400rms watts in a sealed box.

there are lots of options out there but if i were you i'd just finds a hertz dealer and get a setup in your price range and call it done.

Ye i prob do that ,:)

Go to caraudio.com
and don't listen to anyone on this site.
That's about the best advice I can give you.

i trust Subwoofer

checked out my local audiostore for some help and they told me what to look for when it come for speakers/amps/subs
im gonna head next thuesday to another town to get the package (cheaper than expected for all items)
gonna go fill up all speaker places so 2x 4" / 4x 5.25" / 2x 6.5"

never asked what power cable i should use for the amps? (how thick)
and i suppose i can pull 2x power cables on left side and 2x audio+remote on right side without having them interfering with eachother
