i got a cd player that is 4x50w so thats 50w per speaker

if i put the fader onto front speakers only, will that give each speaker 100w? as the rears arent being used, or does it just cut the sound from the rears??

 

It will be 50w to each of the front channels. If you want more you'll need to get yourself an amp. In fact I would recomend getting an amp as they will sound so much better

 

yeh think i will, il see how i get on with them from the head unit first as i havent much dosh at the mo

 

me head unit as 2 pre outs for front n rear speakers, got no sub out, but can i run a amp from the rear speaker pre out for a sub instead? or will it sound shite?

my last head unit had a sub out and i could control the bass volume on the sub seperate from the head unit

 

What I suggest you do is get yourself a 4 channel amp and use two channels to run the front speakers and bridge the other 2 to run a sub. Budget on Ł30 for a cheap amp wiring kit from Halfrauds which will give you power, earth, RCA and remote cables. Only thing you'll need is a pair of RCA splitters (1female to 2male) as the amp will have for inputs and the headunit only has 2 outputs. Depending on the amp you buy you can put a HPF on the fronts and a LPF on the sub without buying any crossover networks

 

If you get stuck mate drop me a PM and I'll be more than happy to help you out where I can
