I've got a hiss coming from my right rear speaker, took it to the local audio store thinking I've got a loose wire, they inform me my amp is blown. Well, b/c BMW uses proprietary amps these guys put the hard sell on trying to convince me to rewire my car, go with an aftermarket amp and oh, by the way, I'll need a new head unit. Estimated cost? $1,200 OTD.
After I stopped laughing, I got their written quote and left.
I'm finding "non DSP" amps from a '98 540i on Ebay for approximately $50. I've got a '97 540i.
I've got two questions:
1) Has anyone else experienced a hiss coming from any of their speakers, and have you determined what it was? I trust those audio guys about as far as I can throw them given their hard sell technique, meaning I'm still not sure it's not just a loose wire or something... How could I confirm my amp is blown?
2) For a non-audiophile what's going to be the difference between the 7 year old BMW amp vs. a modern aftermarket amp/head unit combo? Is it really worth the difference?

65 12 8 374 535
Called green leaf and they don't even track the amps, meaning when they get cars in they don't even look to pull them out - they just throw them away.
I've called 4 junk yards this morning, and it's not something they really have either. Guess I'll just keep calling around.
This sucks - lol.
However if someone wouldn't mind answering whether or not they think it's worth it to upgrade to an alpine head unit and aftermarket amp for a non-audiophile, I'd appreciate it.
Just to throw in my .02Cents, I have had a good experience with the Alpine headunit in my E36 320i and it is a super nice fit for the 3-series vehicles, dunno about the fitment on a 5series though.
My opinion on the e39 because of the I-bus technology along with all the cutting and hacking of the vehicles wiring and the likelyhood of causing problems I would stick with the original headunit and amplifier and if necessary upgrade the speakers or add on to what is already there as far as adding a subwoofer etc if you want more bass response.
All depends on what you are into and what you want to accomplish but keep in mind that BMW's are technical cars and cutting into wires and changing modules on bus systems can cause problems. Stereo installers are good at what they do, thats installing stereos etc but most (and Im not saying all) do not have a good knowledge of the BMW specific systems. Im not saying its impossible to do because it has been done but just make sure it gets done right if you decide to go that route. The most common mishap is that something will conflict with other modules on the i bus and the bus stays awake which results in a drained battery overnight. This is just 1 of many possible problems that can be cause by splicing in aftermarket equipment. Just something to think about.
