In Reply to: Stereo Questions... for the sound guys posted by NuG on February 07, 2000 at 22:36:39:
I would not suggest installing more speakers in the rear deck between the factory speakers. As a second choice you might consider trunk mounted subs but you may want to talk to others before doing so. All BMW trunks are very tightly sealed with little or no cavities to channel the sound into the inside of the car. I understand from some owners that using trunk subs will sound somewhat muddy unless you can fold down the rear seats.
You may want to consider JL's Stealthbox speakers. I have the JL Stealthbox 8" speakers that sound very nice and don't use up any trunk space and no rear shelf modifications are necessary. They produce a very adaquate, tight bass, firing right into the inside of the car. They will pack quite a punch! I understand even though the Stealthbox speakers are made for the E36 coupe, some people have made whatever modifications are necessary and used them in the four-door model.
As for your blown out front speaker, those front HK speakers are absolutely terrible! I don't know if replacing just the front kick speakers with another higher quality set will work for you because the speaker crossovers in the HK system are actually built-in to the HK amplifier and the HK amplifier is really, really crappy! Lots of disortion using hardly any wattage.
You may want to consider changing out the amplifier and the speakers and going with a complete new system. You could keep the HK head unit if you wish. It does a great job feeding aftermarket amp/s and looks good too.
I'm using the JL Stealthbox speakers in the rear deck driven by a PPI PC2300 amp with a manual front mounted gain control and the JL Evolution XR525CS speakers in the kicks with 1" JL tweeters in the doors driven by a seperate PPI PC4400 amp.
I also have another set of tweeters mounted over the JL subs for rear fill and control them by the factory HK speaker switch in the center console for on/off control. I am using the HK head unit and factory CD changer. It sounds fantastic with a beautiful sound stage. I'm able to play it as loud as I want with nice clean full sounding audio!
More info than you wanted but I hope it helps soom.
: Has anyone ever put 2 10"'s in between their 6x9's on the rear deck? I think i've seen it done somewhere and I would like to know how to do it. Do you think that i'd have to cut the metal under the rear deck?
: Also, I have the harmon kardon system in my ///M and I blew the 5 1/4 woofer down where the dead pedeal is... has anyone ever replaced that woofer with a better one? If so, which company makes a woofer in 5 1/4"?
: Lastly, is anyone running the new polk audio/momo sub woofers in their car?
