what car do you have?

did you use a wiring harness?

2001 325i bmw, I used what came with the head unit. No aftermarket harness was used, I just cut and spliced.

Why in the world did you just cut and splice?

you got your wiring jacked up some how for it to behave like you're describing. You need to overlook your wiring again. Get on google and find which color wire does what job.

does anybody know if the head unit on his car is ignition or PCM controlled? Google aint helping me.

get the battery checked out.

then that just leaves the install as being the problem. You might just have to spend more money than you would have originally to have a shop fix it for you.

Okay, maybe I am a bit biased here, but you need to go and spend $10 on an aftermarket harness made for your vehicle. We can provide help, but this should be the start of helping yourself. The aftermarket harness will plug directly into your stock harness, and then you'll have exposed wires to connect from it.

From the aftermarket harness, the 3 main wires are: Power; Accessory & Ground. If any of these are done incorrectly, you'll have a problem very quickly (if the unit even starts).

Connecting the speakers after that is simple, as long as you can read and use a crimping tool or soldering iron.

Out of curiosity, how did you get the radio to work if you just cut and spliced? Your install has FAIL written all over it. (1) You need to remove your aftermarket radio; (2) re-connect your factory wires to how they originally were; (3) purchase an aftermarket harness similar to this & (4) Follow the wiring instructions on the aftermarket radio, and connect the wires accordingly.

since you own a bmw you should know that things are never easy or cheap when it comes to working on them. Was it worth the saving the money you did to have all this headache? Now for the fix, pull the radio and just check out how things are connected. Are they crimped soldered or just taped? Are there more than a pair of wires getting connected in one place? If more than one factory wire are getting connected together that could explain the current draw. First things first is to get a dmm when you pull the radio out and test wires to see if they do have something else that shouldnt be connected to the constant wire or any other wire in there. Myself I would probably disconnect all that they did and start over from scratch. You might also have to run a new acc wire to the fuse panel to get it to properly turn on and off like it should. There is a possibility they have the acc wire currently connected to a data wire instead of an actual 12v switched source. this may be the case if it is a "premium" sounds system. My best advice, stop being cheap and have a professional do it, and not in their driveway.
