Radio is FRIED

So I bought an alpine deck for my 01 379, a brand new alpine. Everything on it worked great, then one morning I leave out and it doesn't turn on. Didn't have time to mess with it for a couple weeks. Finally had the chance to pull it out at about 1 pm, the truck hadn't ran in a couple days. The radio was HOT, I couldn't hardly touch it. I assume it's hot from being so close to the roof. There's a yellow wire in the harness that is always hot and a red smaller wire that is only hot with the key on. My question is, did heat ruin my radio or is there a wire that burned it up? Radio fuse on the back of the radio is not blown

Thanks in advance

 

I forgot to mention the radio worked for a couple months after install just fine

 

I just removed the old pioneer deck that I couldn't play my phone through and plugged in a new pioneer deck. Did not do any wiring.

 

Aw man that sucks to hear. Thanks for the reply though
