Do I bother?
Hi all, just about to finish up my system and I need some advice. Do I install rear speakers? I have a rear channel on my 500.5 of 25x2w. Here is the system details:
Alpine CDA 9811
MBQuart Premium 6.5 Components in front
JL10w7, custom Audio Dave Box
JL 500.5 Amp
Monster 1 Farad DigiCap
CC Insulation Kit
I read the size and I also read what everyone is using. I find that most aren't using rear speakers? I understand in sq you wouldn't want them due to the stage, but why not just for fill? I mean the sub is back there, so thats fine, but no vocals coming from the back?
I could just run the rear chanel to the tweeters seperately instead of using the x-over with the front chanel on the amp or I could just buy some MB's or like for the rears. I only have 25w for each rear with this amp, so I wouldn't want anything that requires alot of power. I would just want good quality sound.
Any ideas?
Thanks

I am with bogus, I would run the tweets off of the rear channel to allow for some fine tuning, generally speaking your mids need more power than your tweets to be "equal" in sound, and most mids need a little more power to really come to life and play some nice midbass. I will have to look up the specs on that amp and see what the best way to wire it up would be for you to allow for the best use of your crossovers.
Does the 9811 have any sort of built in crossover? I had the 9815 back in the day and it had 2/3 way options, can't remember if the 9811 did.

K looked it up, fully variable on channels 1/2/3/4 with a sub crossover on channel 5. Also have 12/24db slope options. I would recommend doing a fully active setup (bypassing the passive crossovers that come with the component set completely). Cross the midbass at 80hz 24db and highpass it at about 2.5khz 12db. Run the tweets at 2.5khz 12db and go from there. Those are basically stock specs. You may be able to go down to around 2.2k or so at 24db on the tweet and match it on the mid but let your ears be your guide on that.

I'm planning running full range speakers. (actually the same SPX 177r components i'm running in the front) I happen to like rear fill myself. I'm running the front and rear speakers off seperate amplifiers though and i'm using the passive Xovers they came with.
