fx4trucker Posted August 24, 2012 Report Share Posted August 24, 2012 (edited) today i notice smoke from my fuse block and the one out going wire to my sub amp was super hot (melted part of the fuse block )... its a rockford fosgate fuse block. i have efx 4ga wire going in and 2 4ga wire coming out ... one goes to my 4ch amp (never have problems there ) and the other to my sub amp (always having problems there) .. so the question is what could be causing this ? never had this problem b4 Edited August 24, 2012 by fx4trucker Quote alpine head unit (freebee 2009 model)2 sets of eclpise 5.25 comp. speakers. 1. set is in the a-pilors 1. memphis mojo 2500 watt amp 1. rockford fosgate t2 15" dual 2 ohm wired to 4 ohm . seeing 600 watts 1. realm audio 600 watt 4ch Link to comment Share on other sites More sharing options...

ROLEXrifleman Posted August 24, 2012 Report Share Posted August 24, 2012 I've never ran fused bigger than 60 amps in those types of holders. Has anything changed to make your sub amp draw more current recently? It seems to be that the fuses and wires are doing their job just fine, it's the plastic that can't hold up to the current demand of the amp. Has the load the sub amp sees changed?

ROLEXrifleman Posted August 24, 2012 Report Share Posted August 24, 2012 Let me clear up my last statement above; The fuse holder can not hold up to the heat produced by the current draw. IRS not the current itself that melts the plastic. Also you said the dub amp has always had problems, what else? Quote Rolex you sicken me.

Has the load the sub amp sees changed? thats the thing nothing has changed .. the sub runs at 2ohms like always .. but i know with just the sub amp line i had the problems .. if i turn up the sub through the head unit i would pop the fuse ... but lately it wouldn't pop get get really hot and smoke .. maybe i should just run another line just for the sub ... or its the amp idk ...

Purplehaze Posted August 24, 2012 Report Share Posted August 24, 2012 The problem is you are running two 4g power wires from one 4g power wire. You need to run a 0g from the batt. to the dist. block, then the two 4g will be fine. You are starving the sub amp for power, causing that line to heat up. Try it, and see if I'm right.
