Hey guys, so heres the deal. About two months ago I got a used jl subwoofer. I then installed it to my mono amp. Then about a month later, my subwoofer and amp stopped working completely. The amp wouldn't even power on. I didn't really care about it, since it was cold out for the past few weeks, but however the weather got better so i went to see what the problem was, first I pulled the radio out and everything seemed fine. Then I checked all the fuses, they seemed fine. Then I saw that the 40A fuse on the amp was blown. So I drove all over to find a new fuse. I finally found one and put it into the amp. Then I went to connect the sub, however everytime i try to connect the sub it sparks bigtime. Im talking about the + - inputs. So maybe I thought the sub was bad, so I went and bought a brand new Alpine Type R. Same thing happens with this sub. Im scared to blow the sub or anything, so once I see the spark I pull the wire off right away. Also Im not sure if my amp did this before but the red light blinks slowly. What should i do? This is pissing me off and costing me too much money which I dont have right now. Why does it keep sparking? What could be wrong with the +/- inputs/outputs. They spark both on the amp and sub. Any help would be appreciate. Thanks
Need some quick help with my subwoofer and amplifier

Sounds to me that your overload circuit in the amp is fried. When the fuse blew it could have melted the internal board so that there is a bridge between the outputs.
What kind of amp is it?? If you hooked up the speaker wrong so that the amp is going to see 1ohm, that would cause your problem.
Give me all the info you can and i will see what I can do.
I have a nice set of jl 10W6 subs. been pushing 800+ RMS to them for years with no problem at all.

and even when theres nothing connected to it, it still shows a red light, i believe it was blue before.

Yep, the amp is cooked.
Looks like you accidentially required 1ohm from the amp. This in turn shorted it out.
Get a new amp and you will be fine, just make sure you hook up the speaker correctly so that the amp will see either 2 or 4 ohms. unless you get a 1 ohm stable amp, than you can have some fun.
Sorry for the bad news, I have burnt up my share of amps in my day.
