well just got the boat and have to spend all the money getting it ready and some other toys for it. So basically looking for the best bang for my buck right now. Either way I want something that is nice and be heard but not from miles away either

They are called components because they are a woofer (6 1/2", 7" etc) and the tweeter (1", 1 1/2"). The crossover filters the correct frequencies to the correct speaker and the two act as 1 channel, or 1 speaker. Its a better way to filter highs and mids than the normal speaker you see with a tweeter built in.

I just finished putting a new system in my boat. Its a 27 Fever so there isn't a lot of spare room. My experience level is about the same as yours so I kept it simple (KISS). I started with a Kenwood KTS-MP400MR Stereo + KTS-RC100MR Remote and connected it to an Alpine PDX-5M 5-Channel Class-D Marine Digital PDX Amplifier and it's pushing 2 10" Kickers on the mono channel and 4 Infinity KAPAs (2 6X9s and 2 6 1/2s) on the other 4 channels. I know the Infinity's aren't marine rated, but I expect them to be blown-out before the weather gets to them. I plan on replacing them with some Polks. I built a pod to mount the remote on the dash next to my compass since there's no room otherwise. And the sound...it's absolutely KICK_AZZ...way more than I ever expected and the subs aren't even broke-in...I admit the subs are low-end, but they'll do for now. This isn't a super-power system, but it works for me...I hope what ever you end up with does the same for you.

thanks what I am thinking is this. Right now there is speakers in the back seat there and two in the cabin. Im thinking about putting marine grade subs in back seat two speakers in cabin with regular stereo and amp in there since it will be out of the elements. Anybody see a flaw in this logic besides a 0 or 2 gauge power wire going to the battery will be expensive unless i can hook into the dash.

It's your boat...if you want 2 speakers in the rear seat and 2 speakers/amp in the cabin...that makes perfect sense. Definitly run the 0 or 2 gauge back to the battery though and use the mult strand wire cause it's easier to bend and work with(car stereo shop is a source). I also put my amp in the cabin. I installed it just above the radio using the access cut-out just above the radio where the mirror was mounted. The PDX-5M was a perfect fit.

Did some looking arond and is this what they consider a 2 way speaker? Also does this replace the need for subs or is it just a better option than a regular tweeter speaker.

No, a 2 way speaker is a coaxial speaker (tweeter is built in, mounted to center of the woofer cone.

Here is an example of a component set

Components are nice because they give a clearer mid bass and high range frequency. They don't eliminate the need or want for a sub though because you will never get that type of base out of a midrange speaker system. Components just give more clarity and frequency separation.

got it now thanks for the help
