I am not quite sure if I understand your question but by 2 way and 4 way, I'm assuming that you mean 2 channel and 4 channel. In this case the number of channels means the number of speakers you can hook up to that particular amp. Also, if you meant 2 way and 4 way speakers, then it is the number of "speakers" in the speaker system. Meaning that with one speaker you could have a few tweeters attached to it. I hope I could help.

First, I would purchase the amp based on the subwoofers alone. Allow unit power to run the 6x9's unless you are planning a intricate setup. Things to think about when buying your amplifier. Always get an amp that offers an RMS output of 25-30% greater than the combined RMS output of your subs. Also, the stability of the amp to handle ohms loads (1, 2, or 4 ohm stable). If you have two dual 4 ohm subs you can get a 2 channel 2 ohms stable amp, or a monoblock 1 ohm stable amp. This will get you the most power and sound for your buck. There are so many amplifiers out there at different price levels, it's really up to you. Hope this helps.

Look, if the amp is 1500watts mono, then you have the capability to run a sub up to the full 1500watts, but i see on the specs for this amp that it has output for 2 speakers, which means up to 750watts each speaker. That's more than enough to power your L7's. They're trying to sell you something you don't really need in my opinion. Hope this helps.

Depending on the PA FUBAR you have. The voice coil on those subs are DVC. Dual Voice Coil. You need to know a couple things. What kind of amp are you going to run on it. And what is the resistance (OHM) rating of each voice coil. MY two 12's are dual 4 ohm. Meaning that there are essentially 4 speakers to hook up. My amp currently is not 2 ohm stable in bridged. So what I did is run each speaker in parallel (red2red,black2black) then run to the box terminal. So now the dual 4 ohm voice coils are basically 2 ohm. I have 2 speakers. Now I hook the box up in series. To bring the now two 2 ohm speakers into one 4 ohm speaker. This is called series/parallel setup. My amp sees this box as 1 channel @ 4ohms. The downfall to this is the output of the amp is divided up into each speaker. So instead of sending all 1400 watts to one sub. I will send 700 to each sub. But here is a catch. even though each speaker is half the total wattage it will still be 3db louder. Meaning it will be as loud as 1 sub running 1400 watts. To conclude i need to know how many of those subs you are going to run on the amp.. And the model number of the amp so I can match up your wiring.

It really depends on your amp most amps you want to keep a 4 ohm load . If you have a high end amp like Rockford or JBL they are 2 ohm stable a 2 ohm load means the speaker will work harder but my not ne safe for your amp . This is how you make a 2 ohm load you have 4 imputs 2 + and 2 - run 2 sets of speaker wire just like you have 2 speakers then take the free end the 1s going to the amp twist them together + to + - to - you can only do this if your amp is bridgeable and is 2 ohm stable look on your amp out puts most amps go to the left + and right - hope this helps

No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw.
WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula)

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you. http://www.diyaudioandvideo.com/FAQ/Wiring/

Everything is a function of Resistance and Ohms law.

Current (I) = Voltage (E) divided by Resistance(R).

Voltage = Current Multiplied by Resistance.

Resistance = Voltage divides by Current.

First lets start with how to run your speakers, If you are running all three speakers then you need to wire them in a series so all three of them are a 4ohm load. you can achieve this by taking the first speaker and running the (+) to the amp, then take the (-) and run it to the (+) on the next speaker, then take the (-) and run it to the (+) on the third speaker, then take the remaining (-) and run it to the amp. Now as far as an amp goes you can pretty much pick any amp you want now and not have to worry about overheating since you are running a 4 ohm set-up.

Fixing them isn't worth it just purchase some new 6x9's for less.

well yeah thats what im doin riht now in my ford taurs what u do is u can hook up your 5x7s and ur 6x9s on ur amp sill have room for a sub the way too do that is get the front speakers off the amp just run the back andsince its a four channlel amp 1 and 2 channel are used for the back and 3 and four are used for thesub of couse u brige the sub to the amp 3 and four are used for the sub hope that helps friend let me no what happens

With a single 4-ohm subwoofer, usually the best choice is a 2-channel amp that can be bridged to a single channel. In your case, the sub is rated for 1000 watts. Not many amps are rated for that kind of continuous power into a 4-ohm load.
Kicker doesn't list a minimum power rating, which isn't unusual in subwoofer specs. Depending on your budget, I'd look for an amp rated for 300-500 watts minimum; the higher, the better, up to 1000 watts.
Most amps will have several power ratings, based on the load impedance and number of channels driven. A typical 2-channel amp might be rated like this:
150 watts x 2 channels at 4 ohms
300 watts x 2 channels at 2 ohms
500 watts x 1 channel at 4 ohms.
The power rating you'll want to look at will be the 1-channel, 4-ohm rating.
You can look at mono amps, too, but in the power ranges you're looking for, a 2-channel amp will probably give you the best value. However, if you can find a mono amp with a high enough 4-ohm power rating, it would run cooler and might last longer than a 2-channel amp with comparable power. When looking at mono amps, you'll find their highest power output will be at 2 ohms or 1 ohm; make sure you're checking the 4-ohm rating when making comparisons.
Some amplifiers that might work well for you:
Kicker SX900.2
Kicker ZX850.2
Alpine PDX-1.1000
Rockford T600-2
Hifonics ZXi 1006
Premier PRS-D2100T
Power Acoustik OV2-2200
