Can anyone tell me how to make an amp out of a pair of spair speakers laying around the house.
#2
yeah, i don't know if that would work. And if it did, i don't know if you would be happy with the sound coming from it.

You need more than damn speakers, theres a number of guides on the interweb if you look

No, I'd recommend pad-per-hole perfboard- it's the easiest to work with.

and how do you work with perfboard ??

It's basically got little copper rings around each hole so that the solder sticks to it.

You put in the components, solder them to the pads, and can either use unshielded wire or solder pads together to do connections.

wow tnx ruby amp here i go !!! (the thing is like 1 watt rms or so right??)
also i wanted to do 2 mods to the design ... first i would like to add an on of switch (that would be just cutting the wire from the baterry to the pcb rigth ?? (spst switch)

and (idk if its possible) add a second gain knob (like little single channel marshalls)

yea surprisingly a little basic 386 amp will sound incredible through a high end 2.1 computer sound system with a sub. the frequency response i get is seriously amazing. building one of these takes very little and not much time other than to box it up, and will give you a little portable amp which will work with headphones, standard speakers, or other amps.

No, I've ran it through a 10" sub (sounded like balls) and I'm running mine through a 5" midrange driver at the moment and it sounds fantastic. Providing the impedance is the same, any amplifier will run through any speaker. Too much wattage and you'll blow the speaker, too little and it won't be super loud.

ok ... so i think ill get the speaker.... was the minimum impedance of the ruby 4 ohms?? ... if thats the case can i run this one without trouble (8ohms)??
if not i can always buy 2 and wire in paralel XD

Sure, that would work. I can't actually see what speaker you're looking at, but I wouldn't go above anything bigger than 10". I'd be using a high efficiency midrange driver around the 6" size, or something like one of the Weber 6" speakers.

thats actually what it is is a 6" wooffer (well wannabe) 100HZ to 6kHz ... round 100 w rms ... 90 db (whatever the sensitivity/efficiency unit is)
all for 15 bucks XD
lets see how much it holds out...

90dB/w/m is very low. If you get a speaker that's between 96-100dB/w/m, it has the potential to be twice as loud.

I've played mine through a 4x12. It was pretty sweet.

lets see if it can handle a Pantera like marshall wall
