Help - Amp stopped working

I'm not much of a car guy but I can be handy. I installed an amp and sub into the trunk of my '94 vovlo 850, myself. By sunday night everything was complete and it sounded good. I almost certainly (not positively) used the cigarette lighter of the car during that 1st joyride around the neighborhood after the installation. Monday morning on the way to work everything sounded fine. Monday afternoon I definitely lit a cigarette whithout the key in the ignition. (Side note: I have noticed a difference in the usage of the lighter while the car is running vs not running - the lighter seems to get stuck, take a long time, and doesn't work well.) Monday night driving home the amp was getting no juice. What gives?

I spent a lot of time installing and all of the sudden it stops working. I checked the fuse box up front and everything was fine. I noticed my radio antenna wasn't extending and that I wasn't getting good radio reception. I checked out it's mechanism from the trunk side panel and noticed a fuse. Checked it, saw that it was intact, and confirmed that I had just broken the casing that it was just removed from (fixing that will be for another thread-jk). Oh and the car lighter still works. The car is notorious for small electrical problems.

Anyone have ideas besides "you're a dumb *** - stop smoking"? Thanks.

 
What kind of equipment? You said you checked the fuse box......did that include the fuse in the fuse holder coming off your battery?
Jensen MOSFET power amp, 300W 2-ch bridgeable model xa2150

Sony cdx-f5710 headunit a few years old

I spent like 70 bucks on the wire set at best buy

The fuse coming off the battery is fine. I'm thinking it has to do with the remote signal.

Do I understand this correctly... you turn the key, turn on the radio, a signal goes to antenna to engage/extend it, returns to the headunit and then goes back out the blue wire to the amp?

 
Disconnect the remote wire at the amp and run a jupmer from the main power wire to see if the amp will power up.

It sounds like you have a short in the remote wire.
