Component Wiring, What Ohms and Watts are seen by the speakers? Options

[WALKER]

So I have a really good understanding of sub wiring, however I am unsure on component wiring. I am unsure how a crossover and component speakers work and am hoping some of you can help me out.

I have the premium 8 speaker sound system in my car with the factory amps, deck, and speakers removed.

I will give you background on the stereo equipment I have gathered and the setup I have planned. I have an Alpine CDA-9833 deck with the internal amp turned off. This deck has three 4V preouts (Front, Rear, Sub). I am using the Sub preout to an 8" powered Bazooka Sub in the back. I am using the Rear preout to run to two channels on a JL 300/4 amp. I am using the Front preout to run to a Kicker KX2 active crossover network. In case you aren't familiar with the KX2 it allows you to amplify the highs and lows separately. So from the KX2 I have the highs (>300Hz) going to the other two channels of the JL 300/4 amp. I have the lows going to a JL 300/2 amp. The 300/2 puts out 150 watts RMS x 2 and powers my 8" Kicker SSMB8 which I have placed in the original 6 1/2 inch speaker location. The 300/4 puts out 75 watts RMS x 4 that will power the rear 6 1/2" speakers (full Hz range) and the front 4" & 1" (>300Hz).

I have yet to purchase the speakers in my setup because I am unclear on what RMS wattage I require them to be rated at. I understand the rears will be around 75W RMS since that is what the amp will put out, so no concerns there. As for the front speakers I plan to run a 4" component setup so that the 4" will be for 300Hz-2000Hz and then the 1" will be for 2000Hz+ or whatever the crossover frequency is set at.

So to simplify the setup and focus on the 4" component setup, I am basically using a 2 channel amp that supplies 75W x 2 and it will be powering 4 speakers (two 4" and two 1"). Is it as simple as that that each speaker would then only be seeing 37.5W each? The total 150 watts would be split by 4 since the sum of the power consumed must equal the sum of the power supplied? As for the ohm rating of the speakers from 2-8ohms each it wouldn't matter for the JL amp since it puts out the same power from 1.5-4ohm load.

I am trying to think if there is anyway possible that the power supplied to each speaker would be the 75W, but I don't see how it would be possibly since that would break the rules of electricity. Please let me know your thoughts. Also when you see that ratings on component systems saying 75W RMS, does that mean that the 4" and the 1" would each only be rated for 37.5W?

Simply put the 4" speaker and 1" tweeter are considered a single channel and the power rating given is for the pair together. Both speaker connect to the crossover and it divides the signal to the proper speaker. The amp only sees it as one speaker so both do get the full 75W.

Have you been able to find many 4" component systems? I Have the premium system also and it's been on my list to replace those. I haven't found any, but I also haven't looked very hard.

I think that because of the scarcity of the 4" speakers that you are going to have to find the speakers you want and then get the amp to match. Not the other way around.

I understand. The 4" and 1" speakers would be wired in parallel so they would see 75W each.

It is very difficult to find 4" ones, however I have found a few. I typically get my electronics from an online store - Sonic Electronix.

So I have been thinking more about the compnent speakers and understand the power supplied to each one of the speaker, but what ohms would the amp see in this situation?

If you have a 2 speaker component system (both 4 ohms) would the amp see a 2ohm load or would it see a 4ohm load?
