Look up the specs online and find out the reccomended RMS of the subs... then find out how many ohms that they're stable at... from there, take that information and let us know... you should be able to make a purchase... also, what kind of budget do you have?... remember that you're also going to have to buy a wiring kit as well.

OK prob:

2 12" subs, 500W a peice. and i'm not sure on how many Watts of an amp i need can somebody help me?

watts the names of the subs, is it 500 rms or 500 peak per sub?

usually you want your amp to be 75% of your max RMS power.

Ok well i need to know everything i'll need to power these subs. I need to know like what goes where... blah blah blah lol all of it. I have no clue on audio... and just got these two 12's for $50 new... and want em lol soo here's the specs:

Legacy LWF12X

any help?

Lemme run this by my friend... I think that I have a suggestion, but I just want to verify this with him...

I beg to differ. You want to be at Max RMS if not more so that you aren't underpowering the sub(s) and therefore run the risk of frying the voice coil due to improper ventilation.

These 2 are among the important specifications that need to be taken in to consideration when matching an amplifier. If you decide to run both subs off of one amp you'd want to end up getting a mono-block amplifier stable @ 2 ohms outputting at least 500w RMS. If you decide to run only 1 sub, a 2 channel amplifier stable @ 4ohms in bridged mode at 250w RMS is what you'd be looking for. When you pick up the amplifier (which ever one it may be) ask the sales dude what he recommends as far as a wiring kit. Most likely, a good amplifier of this size will require a 4 gauge kit.

Bottom line... make sure that when you're talking to the sales person make sure that you are both talking in terms of RMS power not MAX power.

250rms - 4 ohm SVC (single voice coil) x 2 = 500 rms @ 2 ohms

so get an amp that has 500rms at 2 ohm and you should be fine. you dont want to under power your subs, or over power them, but if you dont have a choice, overpower them, it's less damaging.

wire them up in a parallel....so:

1) positive from amp goes to positive on sub1 and sub2
2) negative from amp goes to negative on sub1 and sub2

pretty much straight forward.
