Because old tube tvs were very susceptible to magnetic influence. Decks won't really matter. If you have problems reading CDs then maybe you'll want to look at shielding, but I'm pretty sure the arm is already shielded inside the deck.
I wouldn't worry about it. Plus I've done something similar and the deck still worked fine.
So if i cant go to big then what would be the smallest size i could go? I dont want to build what i would think to be big to find that its not big enouph. Ive tried using a DIY calculator to calculate box sizes but dont understand some of the things it asks me. Im really just looking for a general idea here.
So far it looks like my minimum will be about 8"w x8"h x10"d thus 640sq in per speaker. Those are rough measurements and if i cant go to big then i might do 10"w x10"h x10"d thus 1000sq in. I really dont want to go much bigger than that but again...dont want to be to small
Most 5.25" speakers are happy anywhere from 1/8 cubic foot to 1.5 cubic feet. If you build it on the small end, you will end up getting an increase in output around 160Hz, which is in the midbass range so you'll basically just have to turn down the bass on the deck, or it might sound good. If you build it too big, you'll lose control in the area in and below the midbass range, but if you're crossing over your speakers it will be fine.
