fuses blew in sundown sae 1200

[Wackzirth88 4]

Ive had a sundown sae 1200 v2 for going on 4 years now. Its been ran in two systems/cars both at 1 ohm. I installed it those two times set it and left it(set it differently). Been going strong until today.

My car is a Buick lesabre with a stock 130a alt. My battery is under backseat and power n ground are ran from battery to amp; literally 2-3 ft long runs. My voltage has always been decent; mid 13s is about the lowest I see on hard drops. Today on my way home from work beating all the way here; 15-20 minutes. Right when I pulled into town my bass stopped.upon inspection all 5 30a fuses in the amo popped, the 120a fuse in between the battery and amp did not. All power and ground connections are tight at amp n battery.

Suggestions/advice appreciated. Where should I start with troubleshooting? Open the amp, look for fried connections?

I would check your grounds and terminals at every connection, sounds like you were pulling too much amperage. A bad ground or bad positive will not show voltage differences until there is a load applied to it. Many times it'll be a bad connection or a slightly burnt ANL fuse/etc.

but why didnt the 120 go first?

[Kylar96 132]

if and when you replace them...... and they pop again,.... it maybe shed a tear time...

Anl fuse is the large one between battery and amp? (2 prongs on one end and a hooked prongon other side). I'll check all connections and give each fastner a little turn. Then just replace the amp fuses and test her out?

Dude I already have the feeling she's getting ready to go. I wondered the same thing about the 120 fuse. Already convincing the wife I need new! Lol

big three?

 

 as far as the fuses go.. i would guess that one weak 2 year old fuse blew,...  then boom boom boom boom .. down the row they went... as they are in parallel

[Wackzirth88 4]

No big 3 but I did replace the factory ground with 1/0 knu wire; nothing upgraded off alt tho

Is the amp mounted in such a way that it'd be sucessable to vibration? Vibration is #1 amp killer.

[Wackzirth88 4]

I think its good. The amp is screwed to a carpeted piece of 3/4 mdf with rubber washers under the feet/mounting holes. There are rubber washers glued to the bottom of the MDF n it is screwed to the trunk floor

Tightened everything up, replaced the fuses and its running fine thus far. I'll get more time on it tomorrow and see how it holds up.
