melted speaker wire...help!!

[15bass 10+ year member]

I have a 15" DB drive okur k9 powered by an autotek atc2000.1. The otherday the + box terminal melted n the wire also. I rewired everything with 8g wire. I hooked it up n now it sounds like crap!! I rechecked the wireing, voice coils, and cone. Everything's fine but major distortion. Is it blown? Bad voice coil? Bad terminal?

The DB drive is a great sub other then the mount ring(where the screws go). The rings made of rubber, if u put even one screw in crooked it will pull up the surround. Otherwise this sub hits hard n low.

Check the coils with a dmm. And why exactly did the wire terminal melt?

I have no idea. It worked fine then cut off(only sub).

I popped the trunk n the + box terminal n speaker wire to amp was melted.

All the wireing on the box was fine too. It was just the terminal on the box.

Wireing in the box was fine

How many watts, and what gauge wire?

 

[I Like Waffle]

sounds like the capacitor inside the voice coil may have quit due to low voltage.

2000 Watts, 1000 rms sub and amp. I used 16g, that's Wat the g was inside the box wen I got it.

Id use a minimum of 12 ga on my subs, and 14ga on my speakers is what I use.Recommend using a minimum of 12 ga wire for your subs.Keep all wiring as far away from the amp heatsink as possible also.

Alright!! I figured it out. Cuz the box terminal melted, I took it out. The hole from the terminal on the box caused my sub to over excursion. I just put a new terminal in and it fixed the problem. Thankx tho

not really. the hole created a port with high tuning - anything below that frequency caused the sub to become unloaded - resulting in over excursion.
