Latest Audio Mod on M3 with BSW/Rainbow Speakers

[Kewl X5]

Okay, as you know, BMW audio system just plain suck. The standard speaker system in BMW really has no bass and lack of clarity. Also, despite getting the H/K upgrade, there wasn't really much of an improvement and plus, there was really not much increase bass.

The highs & mids were not as clear. It was actually quite muddy.

Actually the X5 DSP system had better mids and highs than the E46 H/K system.

Well, I improved the bass output with using JL Audio Stealthboxes (two 8" free-air subs). Check it out here:

Well, the bass was better, but the remaining H/K mids/highs/mid-bass were not as clear. Actually, the mids were sounding a little muddy and lack of clarity of the vocals. Even when on Sirius "talk/news" channels, newscaster voice was not as clear.

Well, BSW started to sell Rainbow speakers for their Stage I upgrades. However, since I already had JL Audio Stealthboxes, I didn't need subs nor did I need rear mid-bass woofers since the JL Audio speakers were already there.

However, I did get replacement Rainbow 2-way speakers, I think it is a 6.25" woofer for the bottom of the door and 1" Silk-dome tweeter. Also, got the BSW mid speakers replacements for the front doors and rear side panels.

Since I ordered the Rainbow Speakers and BSW Mids at the same time, BSW actually pre-installed the BSW mids with the Rainbow tweeters.

Once installed, you could hear the difference in clarity with the mid-bass, mids, and highs. You don't realize what you are missing until you get the upgraded speakers. It matched well with the JL Audio Subs.

Here are the pictures of the install with the help Custom Cellular's install guy. He also installed my JL Audio Stealthboxes before.

Here are the pictures of the door with the door panels removed. You can see where the stock speakers are located. You can see the side air-bag module on the door as well.
