4 4ohm speakers to 1 amp??

[BZA 10+ year member]

Im working on putting speakers in my boat tower. I have a set of 4 4ohm MB Quart RCC 6.5 coaxials to install. Each speaker has a + and a - for the tweeter on one side and the woofer on the other. Looks like this:

Now I just need help with how to wire all of these to 1 amp. I also need help with picking out what amp would be best for these speakers. All I am really tring to to do is get maximum output. I understand all 4 can be run parallel at 1 ohm or in a parallel series at 4 ohms. I just want to know what is best for them.

Heres the specs:

Nominal Power Output: 50W RMS

Max Power Output: 120W Tweeter: ¾" (19mm) Titanium dome

Woofer: 6½" (160mm)

Polypropylene Cone

Crossover: 12 dB/Octave @ 4500Hz

Impedance: 4 Ohms (nominal)

Freq. Response: 40Hz to 32,000Hz

Sensitivity: 85.5dB

Frequency Response: 38 - 32.000 Hz

Any help would be great!

Well you're going to need a crossover of some sorts, you can't just hook the tweeters and woofers to the same signal.

So I've been doing some research and I'm starting to get it. I'm assuming tho that I need 2 crossovers here then??

You're going to need 4 crossovers, one for each set, if you are using passive.
