A partial fix, anyway...

Hey guys,

I played around with the system some more this afternoon after giving the Max her first good cleaning in some time (she's all shiny now ). I decided to turn the gain down all the way on the sub amp. When I do this, and the RCAs are connected to the amp, I still get the hissing noise, but I cannot hear any distortion in the components when the bass hits. Even with the gain all the way down, the subs are still getting substantially better power than they were before the partial big 3 upgrade I mentioned, so I think for now, the low gain setting is good enough.

I still want to find what the root cause of the hissing is. My only theory now is, like I said, that the RCAs might be too close to the power wire for the one amp. But anyway, I set up the equalizer, TA, and x-overs so that the stereo sounds pretty damn good now, and obviously when the volume is loud enough I only hear the hiss between or at the end of songs.

Also, Don, did you ever find anything out about the steering wheel control wires?

And one more stupid question: I can never seem to figure out which order to adjust the audio settings in. I started with the equalizer, then did TA, then did x-overs, but I feel like maybe I should be starting with the x-overs, then doing the equalizer, and then TA? So many settings...

I would set the HPF and LPF then take it from there. it is odd that this new sound is coming with the Eclipse...

definately do the XO first, it will make a substantial difference with tuning the EQ as you may be bumping and cutting something that would be there after the Xover adjustment.

Are you active yet?

Oh yeah, I was active with the Alpine for a few weeks; I changed it over after I bought the RCAs and power wire from you. So yes, I'm active.

Did you notice a big difference with an active 2-way compared to a standard setup?

I noticed a big difference with an active 3-way setup , yes. The invdividual speakers aren't getting any more power then before, as I had one 50 watt channel dedicated to each set of tweeter and woofer before, and since a passive crossover sends the same power to each speaker, each speaker had 50 watts. Now, each speaker has 50 watts again, but obviously they each have their own channel.

The ability to play around with the x-over in the HU to make it sound just like you want it, rather than having to go by what the speaker manufacturer felt was a good way to split the frequencies between the speakers (passive x-over) is definitely nice. It can potentially lead to a very big improvement in SQ. Also, with the active Eclipses, you get one 5 band PEQ for the tweeters and one for the mids, and also a 1 band for the subs (or low, depending on how you have it set up). So basically, switching from the Rainbow passive x-overs to the active x-over, especially in the Eclipse, I have a ton more bass in my mids, and I was able to get rid of the problem where the tweeters sometimes overpowered the mids.

Oh, well I wasn't too sure either, so I read up about it over on the caraudio forums. Seems a 3-way setup is tweeters, midbass, and subs. A 3-way front stage is tweets, midrange, and midbass.

Don? Is this right?

Ah well a true 3-way in MY eyes is a Midbass, midrange, tweet up front. I guess the way you have it though would also be considered 3 way active. So those with 3 ways up front and subs technically have 4-way setups however they may use seperate processors. I usually only consider active = for the front stage. Subs IMO are like a seperate entity.

Yeah, I guess that does make more sense.

Well when there were rumors of the CD5000/CD7000 coming with a 4 way active setup it would have included the sub, so I don't know what to think 100%.
