I'd really like to compare notes with you, as it sounds like we almost duplicated the same set-up. I've done a few upgrades with past cars, all 3 series
though. I bought my 530i about 2 months ago, and of course the factory system stunk. After being in my last car for 5 years, I had forgotten how bad the
factory systems really were. The one thing I wanted to keep this time though, was the weather band in the head unit. And since the car already had the
Alpine factory CD changer, I figured I'd just go with a speaker/amp upgrade.
I've been a Polk Audio fan from 15 years ago, and even though they've gone a bit commercial, it's still a pretty good product. I used the old MM5520 co-axes
in my 318is. So for the 530i, I got the EX2550 2 piece components for the front, and the newdb5520 co-axes for the rear. Then to keep things clean in the
trunk, I wanted a 5 channel amp, so that I could include my Bazooka tube that I would pirate from the 318is. I've seen the comments about setting a 10" sub
driver to blow through the rear arm rest/ski sack location, but what I like about the tube is it's portability. Since it mounts with straps, if you're ever
tight for space in the trunk, you can detach and remove it in 3 minutes.
I ended up going with the new Sony Explod XM4053eqx for the amp. It's a 4x40 and 1x100, with a build in equalizer and variable high/low pass filters.
Crutchfield had a nice clearance on a Clarion 5 channel, but it sold out quickly. They were $399 on this Sony, and then I came across a web site called
AutoToys.Com. It's a audio/accessories retailer out of NJ that has some interesting stuff, and even more interesting pricing. The Sony amp was $275 there
on special, but the special prices fluxuate almost daily. I've seen it for as low as $257. What really grabbed my attention though, were the MB Quarts that
Quart is high end enough that it hasn't filtered down to the discount/net retailer level. I was able to get both the components for the front and the co-axes
for the rear at what amounted to 30% off of msrp. The classic series 213 components were $230, and the model 1213 co-axes were $95, compared to $199
for the Polk components,and $80 for the Polk co-axes. As much as I like the Polks, the Quarts are unreal. No matter what you put through them, you get the
feeling that they're saying, "keep it coming". I know the only thing that could limit them is the amp, which I'm not going to change at this point. I do this
for my own enjoyment in the car, not competition.
Anyway, the only problem that I've run into is white noise. It's definitely input signal related. I get the hiss with the system on, but at volume 0. The hiss
will cut out when the cd changer is changing between discs, which again tells me it's the input signal. I've also tried using an alternate source going into
the amp (my portable cd player with a pre-amp output), and don't get the hiss. I spliced RCA ends onto the factory twisted pair in the wiring harness, so
I'm thinkning one of two things. Either my splices aren't shielded enough, or I'm picking up interference from the power supply line.
Since you've kept the factory wiring harness in tact, I'd really apprecite knowing if you experience any of the hiss - assuming that you're using the factory
head unit. It would help my diagnostic process.
