Impedence of woffer tweeter mix
I just ordered 4 of these woofers which are 8 ohms,I also ordered 2 phonolic ring tweeters which are 8 ohms.If i parallel 2 woofers then hook the 8 ohm tweeter on the factory Dayton 2.5 k crossover and set the plug for 4 ohms will that be OK? Any advice on how to connect these ? Or should I order 4 ohm woofers? My amp will drive 4 ohm loads.
Let's try to work on those questions... When using a stock crossover - it's best to design to its impedance. Don' worry about your amp. Most amps can handle 4 or 8 ohm loads without issue. When you design a speaker and mix impedances - you're better off custom building your crossover. This is easy to do with a crossover calculator. You plug in the impedance of the drivers, choose the type of crossover (6db/oct etc), the crossover point and it shows you a schematic and the part numbers... To keep it simple - use one woofer, or 4 in series/parallel per side which keeps the same impedance.

If i put a 4 ohm resistor on 2 of these wired in parallel will the load be 4 ohms?
If you wire two of these in parallel, the load will be approximately 4 ohms. As a general rule, you should avoid using resistors in woofer circuits.

replacement of blown speakers
i have 1 infinity sterling video center speaker that both of the 5.5" speakers have blown surrounds and maybe blown voice coils. i am looking for replacements would your p/n 292-405 work in it for replacement speakers?
If the nom. impedance is the same as the original Infinity drivers were, these should work fine with the existing x-over. Final SQ will depend on your opinion, but these should be a good 1st try.

hey i was wondering if i had a 15w amp and used 1 speaker on each channel(2 channels total) would it be bad for the amp
No, this speaker would be perfectly fine on your 15w amplifier, one speaker per channel.
