heat issue

[rabidmechanic05 0]

this is the first time ive seen or heard of this......but my d-block is melting........i recently put in some rl-i 8s, turned the gain up a little bit, didnt change anything else. the amp itself is not getting any hotter, but the end of the fuse and the base under the connection to the 8awg is bubbling. what is causing this and what can i do about it?

the amp is a diamond d3400.2

subs: rli 8" d4

running 4awg to the fused d-block *konfused d-block* and 8awg after it

my DMM is currently MIA otherwise i would test my current draw on the amp

A loose connection would add resistance, leading to heat buildup...make sure all the connections are solid.

recently checked all that cause i had a bad case of rfi in everything from doors to deck to subs

what size fuse(s) are in there? are they good? not just good as in they are intact, but good as in they are allowing the curent to flow with little to no resistance. bad fuses will also increase resistance and heat buildup. especially if your drawing more current they are designed to allow, yet won't pop.

i've got a memphis distro block sitting here in front of me melted due to too small of a fuse (80amp AGU) going to too large of an amp (memphis 1500d). fuse never blew, but it sure melted itself to the plastic housing.

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

eee

yup, it was the fuse, swapped the 80A for a 120A and now its nice and cool......even though the sub amp side is at about a 40 degree angle, got really bad when i put in an american bass sq-880

cool, glad it's worked out!

wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Corrosion will also increase resistance.
