The original wattage of speakers. OK! Just to let you know that a set a of speakers are rated to a certain wattage. Peak power and RMS power. Anything over peak the speaker might blow! Anything under RMS and you get the cut off. So if a speaker is rated at a 100 watts PEAK you want half!(50 watts RMS) But if the speaker is rated at a 100 watts RMS a go half the speakers will not work(PEAK will be about 200 watts). So make sure the amp can push about a little more then half of the peak power of all the speakers. It all depends on the kind of amp you are using to.It can be a mono amp for a sub or a multi-channel amp for a set of speakers or a sub. In my SUV I had two 4 channel amps for my 4 12" subs. Each sub has voice coils at 4Ω. But because each sub can have 2 channels and have voice coils I can bridge the sub to 2Ω .So I have adequate power at all times. There always a way to to get the right power just how you go about getting that power and how much to use is the tricky part. BTW when your done how about some pics.

Its a 15w rms x 2 channel amp. I had to get a mono converter, because their is no, I'll say computer to split up the signals. ie left sound goes to 1 chan, right goes to the other, so now I have a mono feed going into both channels. So to continue, the speakers are 5 watts each, doesnt say rms or peak. So if I hook up 2 to a channel, and its 15 w rms a channel, I should be fine, no? Also the sub is 15 rms so its *spot on* Should I try without the equalizer? I think its maybe a bit to underpowered to make full use of the crossover just because it has to hit certain frequencies. Ill try it out, I actually dont have an ipod yet, so I wont know, I'm using my cellphone to test it out with. Ill be getting my piece's of wood cut next week, I'll just need to get the circles cut after, very precise job so I'll need to make sure all my calculations are correct. I have found clear silicone to cover up the edges so it will be air tight.
Just confirmed, it ONLY cuts out when the crossover is connected. So, do I really need it? If anything only the sub could blow? But then again, its only 15 watts, so does it make that much of a difference? Which leads me to my next question, do I need to make the input mono then? If the sub is running without a crossover, then I should be able to give it its own channel, or is it still better to split up both channels into mono? I will also put the port in the back, since that's how most bookself speakers have it, no?
nd I still need help with that calculator. If I dont need the crossover, I can make the box smaller if need be. But how do I figure out all of those numbers? I only have the specs for the sub (
http://www.logitech.com/index.cfm/sp...s/232&cl=au,en) I cant find the link to the 2 speakers, there a very old yamaha 2.0 set, maybe 10 years old. I had the link, but lost it in my history. Almost done guys, thanks!
