I have 2 8 ohm 10watt speakers that im trying to use to make a speaker system for my mp3 player. I hooked the mp3 player up to the speakers but it wasn't quite loud enough, its also going through a filter capacitor first. what do i need to use to amplify the signal coming from the mp3 player? Or is there another way to do it?

Re: making an mp3 speaker system
You need an integrated amplifier like the ones used in stereo systems. The output of an mp3 players is at a level only sufficient for headphones and must be amplified alot to provide the current needed for large speakers.

it is load resistance. set the amplifier switch to the resistance ( X amount ohms) to match your speakers. Although running 4 ohm speakers at the 8 ohm setting is louder, it will hurt your amp
most home/semi pro speakers are 8 ohm, while car speakers are 4 ohm. If you are doing a multi speaker pa/intercom install use your formula to calculate total load is 2 8 ohm speakers in parallel are four ohms . express them as fractions and add the denominator ie:8/1 +8/1 = 8/2 or 4/1 or 4. now connect that in series (add the top numbers)with another 2 speakers in parallel and you get back to 8 ohm load. repeat the same process over and over and you can hook up to 32 speakers to the amp without needing the 70 volt tap. hope this helped.
what amp? the speaker wiring depends on the ohmage rating of the amp. if the amp is 2 ohm stable, then you can hook 2 TS-W304C's up to it, both positive leads from the speakers attached to the amp positive, and both negative speaker leads connected to amp negative. this is called parallel wiring, and it reduces the ohmage (resistance) down to 2 ohms. your speakers are 4 ohms, and 2x4 ohm speakers in parallel makes it equal 2 ohms. if your amp is only 4 ohm stable, then you will only be able to hook up one of your speakers to it.
your speakers are of an incorrect ohmage, or you have too many speakers hooked up to it. your stereo likely calls fo a singler 4 ohm (4?) speaker per channel and the factory speakers may be lower than 4 ohms, or you have several speakers hooked up to the same channel. there should be 4 channels, each with no less than a 4 ohm (4? ) load. two 4 ohm speakers wired to the same channel in parallel (both attached to the amp's poositive/negative leads) will create a 2 ohm (2?) load, and overheat the amp. if the 2 speakers are a woofer/tweeter combination, and there is a capacitor involved, it may be ok, but 2 woofers, or a woofer and a subwoofer hooked to the same channel will likely reduce the ohmage below 4 ohms (4?). look at the back of each woofer speaker, and look for an ohmage rating stamped to the back of the speaker magnet to verify that they are 4 ohm (4?) speakers, and verify that only a single 4 ohm speaker is hooked to each channel. the car likely has multiple speakers hooled up to each channel, which would lower the ohmage rating below 4 ohms (4?).
I researched your amp and it looks like its not even 2 ohm stable :( the problem with these companies is they lable there amps 1200 watts MAX, that means they tested the amp in a perfect enviroment and the amp fried somewhere in the ball park of 1200 watts, your best bet is to save your money and buy a nicer amp that is two or one ohm stable... that being said the best way to wire your subs is in series
If the amplifier supplies a different resistance rating (ohms) than the speakers draw, it might automatically shut down the amplifier to protect from damage. Make sure the Teac output matches the speakers required input. Hooking up speakers that draw 8 ohms to an amp that supplies 2 ohms can cause amplifier damage.
answer depends on what kind of Ohm Load your amplifier is capable of as a lowest allowed setting.
ie if you have a 1400W at 4 Ohm amplifier, the connection would need to be different than a 1400W at 2 ohm amplifier.
also, on the speaker what is the rated ohm load per coil since it's a quad coil speaker (should say somewhere on it's box, or in it's manual. I'd assume 4 ohm per coil)
we'll do that math after you get those figures in to me.
