suggestions for 4" speakers and tweeters for my retro project

[roope]

Hi, im currently shopping for speakers for my retro project
im using an old jvc case which housed 2x4inch speakers and 2 microphones, and it will house amp6, 9A 12V battery and the upcoming speakers.

So, which would be good for a set like this? been lurking around the forums for awhile and atleast monacors should be a good choice. atm looking at sp-40's but what are your thoughts on the matter?

also, will post pictures when i get the electric work done

pps. what kind of potentiometer should i use for volume adjusting with amp6?
also doing a kill switch

Haven't built a boombox yet, but I've heard a few things ... Well, get as high sensitivity as you can, and don't buy car audio speakers unless you know 100% what you're doing

Monacors have been used, yes, and appreciated

And for the volume pot, any stereo logarithmic pot of about 50 kiloohm impedance will do fine. (E.g. almost all audio pots.)

Kill switch? As in to put the amp into mute? Any switch. Literally any switch. Almost. You can use a pair of rusty nails if you like.

ive been doing some lurking now and im about to order either SP60/4's or SPH-30X/4's as my drivers and DT-25N's or DT-99's for tweeters.

any suggestions on crossover with these? box is approx 4-5liter
