Random electrical inconsistencies

Last Tuesday I got in my car and drove. When the stereo powered up I realised the front speakers weren't working. The rears and the sub were fine, but nothing from the front woofers/tweeters. After 30 seconds of switching songs and playing with the volume, the front started to cut in and out, and then finally worked. -it's worked fine since, but it's weird, I installed it myself so I know everything should still be connected 100%

Thursday, as I headed to the car, held down the unlock button to roll down the windows, and the passenger went down, but the drivers one didn't move. got in, started the car, flipped the switch and it went down no problem. Haven't tried, the windows since, but I will today and post and update.

Yesterday (Sunday), as I walked to the car I unlocked the door, nothing happened, closer, unlock, nothing, standing right next to it, nothing. tried the trunk, nothing. put the key in and unlocked it manually, reached in and flipped the switch on the console, everything unlocks, close the door, press the lock button. nothing... first thought it was a battery terminal (which pops off about once every 3-6 months - crap aftermarket battery came with the car) but that's fine. when I got home, closed the door, and pressed lock. everything locked. Unlocked the trunk, it unlocked. Been fine since.

So anyone out there have any idea's what's been up with this little guy? What I might check up on? Pretttttty weird...

So it has to do with the way I wired up my stereo/amp/sub? That is affecting my windows and locks, but only sometimes?

Leaf Fan - That was the issue with my car. The simple diagnostic fix was to disconnect the aftermarket radio / harness from the car. If the problem goes away, it's in the wiring. If not . . keep looking. It was frustrating before the found the issue at the dealership as . . . one day everything would work and the next day totally unrelated things (door locks, A/C, tach, etc.) would stop working. When I put key into the car, I never knew what going to work or not work.
