Terminal cups bad?? Do they melt?

[yowhobedat 10+ year member]

Im in the middle of makng my box, and i already attached a terminal cup. I read that they melt. Im running 1200watts rms. Should i take the cup out n seal it up with wood, or should i leave the cup in place and just not use it, or just use the cup?? Any suggestions would be appreciated befoe i seal the box up.

Ps - its my first box im making, its coming out pretty good lol

u will be fine using it.. alot of people prefer not to use them tho.. but ive never heard of them melting thats a first for me..

they can melt...but you would have to be passing alot of current through it, if you've already cut the hole use it, but i dont like to use them because they add resistance

Jtomsic, how is that hifonic amp for ur comps ?? I need an amp, n dont wanna spend 300 on it at the moment.

Would u suggest just not using the cup, and running the cable through the port?? Or make a hole in the box?

The. Cup is alreadi installed, i could jus not use it n go a different route. I want the most efficent solution

drill a hole in the box just big enough to pull the wire through....then cone it up on the inside

never had a terminal cup melt, not even the cheap ones. hell i was sending 2k through a little cheapie and the sub smoked (thermal failure) before the terminal had any issues whatsoever

Should i take the terminal cup out, or just leave it? Whats a good size for 1200 watts, 10 gauge??

10g will be fine. no point in taking out the cup, might as well use it.

yeah the amp is fine, pushin my components great and doin the rated power so i cant complain.. as far as the cups..you will be fine just use them with the 10ga u were planning on using.

i dont use anything smaller than 14..but for a sub i like to use 12 just because 10 is usually a single wire and you can get 12 paired together

what if ur running multiple coils and wires have to be ran a certain way...then you'll want a seperate wire.. i prefer atleast 10ga when running speak wire to subs.. im running 8 ga now.

Ok. Thanks for the help evryone.

The sub im getting is dual 2 ohms. N i have 8 gauge cable at my house. Should i just buy 12 gauge so i can wire them internally, cuz i doubt 8 would fitWat do u mean seperate runs?

Subwoofer Wiring Diagrams, One 2 ohm Dual Voice Coil (DVC) Speaker

go there for how to wire your subs... by single runs i mean a single run of wire instead of smallre guages that have 2 wires in the insulation for +/-

you wire the subs inside the box off the voice coils to the impedance you want to run them to run with the amp you bought..

Yea i know how to wire them. I meant, i dont think 2 8gaugE cable is going to fit into one terminal on the sub, because you have to connect 2 positives n 2 negatives together
