Radio fuse keeps blowing

[Lunatrix13]

Hello,

This is my first time on this site, I'm hoping someone can help. I have a 99 Honda Civic, I've had a new sony radio in my car since September and has been working fine. Randomly the other day my radio fuse died. I changed it to a new 7.5 and it worked fine for about a day. Now every time I put a new fuse in a blue light sparks with a popping noise and blows the fuse. Where do I look to next? Any help would be greatly appreciated!

Thanks

u might have a short somewhere. check all ur wiring again. make sure that no wires are open to touching metal or any of the other wires
