Hi everyone... I thought you guys could use this info seeing as Bose guards their speaker info like the CIA gaurds missile launch codes... I measured these readings with my multimeter set on the most sensitive setting. All of these measurments are for the [RPO code] UQ7 Bose speaker system. Non-lux (Premium) and Lux have the same speakers. The only difference is the amp. So these measurements apply to both lux and non-lux UQ7 speakers.
FRONT SPEAKERS: ~3.3 ohms (remember this includes the tweeter because the front speakers have the tweeters wired in parallel with a capacitor to act as a cross-over)
REAR SPEAKERS: ~4.8 ohms
SUBWOOFER: ~3 ohms per voice coil (remember the sub is a dual voice coil unit...I am 99% sure the amp is wired to the sub with the voice coils in parallel but I am not completely positive)
These impedances should help you out if you want to replace the speakers but still use the Bose amp or replace the amp but keep the speakers. I recommend NOT to do the latter...aftermarket speakers will have some improvment when hooked up to the stock Bose amp, but if you keep the stock speakers and use an aftermarket amp, it most likely will not have any sound improvment.
OK another interesting thing I found. My first TNR/LUX conversion I did in my dad's '03 Tahoe, I used an '044 Hummer H2 lux amp. When I did the conversion in my truck ('05 Silverado HD), I used a '992 Escalade lux amp. I set the bass, treble, DSP, etc.. exactly the same in both vehicles. I got used to driving my truck and just today, I drove my dad's Tahoe...WOW!! The two amps DEFINETLY are different (im not sure if the DSP, EQ or whatever is set differently...) The H2 amp (part # ends in '044) has a VERY noticible clarity increase, but most of all, MUCH more bass. I thought it might just be my speakers in my truck that were maybe different. So a few minutes ago I did a quick amp swap and sure enough, plugging the H2 amp into my truck increased bass and clarity by a very noticible amount. Sooooo.... Case in point: USE AN ['044] H2 AMP IF YOU CAN FIND ONE!!!! IT DOES SOUND MUCH BETTER!!!!! Luckilly my dad probably wont notice that I ended up switching the amps (I kept the H2 amp in my truck and put the Escalade amp in his Tahoe)
Hope all that info helps!!
