SRHBigMike Posted July 6, 2010 Report Share Posted July 6, 2010 (edited) Ok guys I have had a horrible day with my audio. I have 2 inch Alpine Type R's wired to one ohm and a sundown saz-1000d amp. But today I was bumping for a short time for a parts run. I noticed my bass was not pounding like normal, I have had a problem with my box sliding around. Once my wires came out of my box while i made a hard turn, I fixed it asap. That was a few weeks ago and i havent had that problem sinc. But after I made my parts run I decided to check out my box to see whats up. I left the music on a high volume and as soon as I opened my trunk I smelled burning and looked at my subs to see one out of phase and blown. When I got home I checked over everything,my wiring the same no change everything connected good. Then I cut my car off then went isinde, then came back to turn it back on...my amp would not turn on. I checked the rcas and all 3 fuses and it was all fine. Then I opened the hood to check my inline fuse, my fuse holder itself. My fuse holder began to melt itselff to my power wire on both ends!! The fuse inside was not blown but the fuseholder and wrie began to melt together. I switched to a different fuse holder same type and fuse and my amp worked. So I have a fucked up unusable fuse holder and a blown sub. I am more worried as to why the holder melted, anyone have any insight or advice??? i edit: I took my subs out of the box when i got home. The voicecoils in both subs are still shiny as hell. But the one that I think is blow is hot to the touch and stinks, But both look fine...

bassHZ Posted July 6, 2010 Report Share Posted July 6, 2010 (edited) resistance! what kind of wire gauge are you using? and i dont think its blown i think if it was it wouldnt play someone correct me if am wrong, maybe u just got ur gain up too high.

C-Fizzy Posted July 6, 2010 Report Share Posted July 6, 2010 check the coils with a DMM, and that mishap with the fuseholder is almost becoming common. The holder itself melts with the fuse and it blows without looking blown. Quote under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy?

SRHBigMike Posted July 6, 2010 Author Report Share Posted July 6, 2010 resistance! what kind of wire gauge are you using? Four gauge for amp power and ground, and like 14 gauge for my sub wiring... Quote Link to comment Share on other sites More sharing options...

Guest Posted July 6, 2010 Report Share Posted July 6, 2010 (edited) fuse holders usually melt because the fuse gets so hot it melts the plastic casing. this can be caused by running rated power, or close to, through a fuse. example: pulling 50 amps of current through a 50 amp fuse. i hope you put a fuse in the fuse holder that matches the size of the total fuse amount on the amp. either its that that caused the melting, or a short on the power wire SOMEWHERE along the run of wire. edit: jl_audio reminded me of something. if the wire isnt tightened down STRONG on the fuse holder on both ends, resistance will cause the wire to heat up alot.

bassHZ Posted July 6, 2010 Report Share Posted July 6, 2010 (edited) Four gauge for amp power and ground, and like 14 gauge for my sub wiring... so its a 1000 rms amp right ? is it like a name brand wire 4 gauge i am not the most knowledgeable person but ama try to help u with what i can my fuse holder melted like a year ago and replaced it and never happen again i think i hooked up the wire wrong to the fuse holder which cause resistance=melted fuse holder Edited July 6, 2010 by jl_audio Quote Link to comment Share on other sites More sharing options...

I was using a eighty amp fuse in my holder but there are 3 30 amps fuses on the amp = 90....can 10 less amps completely melt a fuse holder to a wire??? It was tightened very strong, I could not pull it off or tug the wire from it. I pushed down on both subs, they both pushed without a problem. And the voicecoils are still copper!!! But the blown one is out of phase and smokes. It was really hot when it came out of the box but my other woofer is fine. They are both on the same circuit is that possible to blow one and not the other? Edited July 7, 2010 by SRHBigMike Quote Link to comment Share on other sites More sharing options...

sewerman Posted July 7, 2010 Report Share Posted July 7, 2010 Maybe I'm stupid, but I fuse for the size of wire at the battery. 120 amp fuse or so at battery in ur fuse holder. Then ur fuses in ur amp protect it. U don't want to put a smaller size at the battery than u have at the amp. Like feeding a fire hose with a straw. U limit the end result.
