Hey guys,

I have a 2003 E53, non-navigation, non DSP.

I went to the crutchfield site (which is great btw) and looked up speakers for my e53.

If I want to upgrade the sound of my car, can I just buy the speakers they sell, will that be a good enough upgrade to the car?

I pretty much want the easiest sound upgrade possible without sacrificing space in the car. Would I need to buy an amp and/or sub also?

Thanks!

It depends how particular you are. I'm not an audiophile. I upgraded my speakers and added a subwoofer with amp from BSW many years ago. It was a significant improvement and I feel it was well worth the expense. About a year ago I replaced my factory unit with an Android based unit. The sound is another leap forward and was all I wanted to spend.

Where did you put the subwoofer and amp?

I was thinking of doing speakers and an amp. I wouldn't know where to put a subwoofer, as I need all of the trunk space and can't have a sub taking up space.

I purchased a kit from Bavarian Sound Werks. I don't think they offer anything for a 2003 anymore. I have read about many other routes members have gone that are plug and play as well as custom installations. If you don't get input you need in this thread I suggest starting a thread asking for suggestions. There are subwoofers that will fit behind the hatch where the fuse box is in the back and amps that will mount behind the hatch on the drivers side.
