[jaycross 10+ year member]

ok ive had my subs hooked up for about a year and they are just some cheap jensens so its not like i have alot of money in em but i unhooked em and took em out so i could fit some more stuff in my blazer and now everytime i try to fire em thres a huge spark and it blows the fuse. i have tried everything and i even took it to my friend who is really good with this stuff and he couldnt figure it out either. i know that everything is hooked up fine but i dont have many fuses left and i think i went through about 30 of em today.... please someone tell me whats going on.

Do you have the subs wired to the correct ohm rating? IF you don't then your amp may be seeing to low of a load and trying to pull to many amps through the fuse which would blow it everytime.

sorry for the crude drawing.... and this is a 300w jensen amp powereing 2 jensen subs.... please dont make fun they were dirt cheap and sound ok

if its blowign right when u plug it in there is an issue with the amp..are you sure your hooking it up correclty + + and - -

You might've shorted out the output section of the amp.Or even the power supply.

have you taken the sub out of the box and looked at the wiring inside the box?

 

[jaycross 10+ year member]

no i have not because it has worked fine for the last year and i have never touched anything inside the box

i'd do it anyway. you seem at a dead end.

well its really weird because it will sparck and blow the fuse before i even turn the car on. i start by disconnecting the fuse holder under the hood, then i set up all the wiring on the sub and put in a fresh fuse, then when i re-connect the fuse holder under the hood.... the spark comes.

any ideas from that?

sounds like power wire got cut, check where it comes in through the firewall... assuming you're not using a gromet.
