Phoenix Gold Phorum

A recent thread got me thinking about this. I've always wanted a ZPA or two from way back when I first got into car audio in the mid 90's in college, but couldn't afford it.

Now if for some reason I could find two 0.3's in good shape, hopefully with the caps replaced, I'd run one to my tweets, one to my mids, and run them along a Ti600.2 to my sub, so I'd have the ability to do an LPL. Something like this:

Headunit -> RCA -> Tbat -> Balanced Cat 6 -> EQ232 -> Balanced Cat 6 -> ZPX2 crossover...

From the crossover, I'd go:
ZPX2 -> Balanced Cat 6 -> ZPA for tweets
ZPX2 -> Balanced Cat 6 -> ZPA for mids
ZPX2 -> RCA -> 600.2 for sub

Now my question is with the line driver an EQ, since I know the ZPA's need 8v inputs to get the most out of them. So I'm guessing I could crank up the input voltage for the ZPA's, but be limited to whatever the 600.2 could take, since the line driver/EQ are in line before the crossover.

Does that make sense, or did I just confuse the hell out of all the phorum members?

you think the Ti will not like the higher voltage input? Is that what you are saying?

Yes, actually, that's probably the best way to say I what I'm thinking. Don't ask what I typed above, it's been a LONG ass week.

Yeah, just worried the Ti wouldn't like as much voltage as the ZPA's, so the Ti would be the limiting factor.

Hmmm.
How about 3 ZPA's ?

As much as I like the idea, I don't think I can run them fully balanced like I'd want, and be able to do an LPL. Neither the ZPX2 or EQ232/EQ30 has an LPL port.

Plus I've read several times on here ZPA's will be more beneficial to the highs and mids than subs, so that's why I thought if I kept the Ti600 on the sub, wouldn't be missing as much (compared to running a 3rd ZPA), and I'd have an LPL.

you should be fine, I gave my Ti600 the full 8 volts from my 215iX for years with out fail and the ZX450

Ah, good to know. I didn't think it was all that big of a concern, and right now is just an idea. I haven't even got my system installed yet, so I'm sure I'll see how my 500.4 and 600.2 sound before I go buying ZPAs.

Of course, I was just going to go for a "simple install" when I started planning this several months ago. You know how that goes, now I have so much stuff stacked in my office my wife thinks I'm nuts.

I have a line driver on my octane le and it LOOOOOOVES it. I added it after the fact and it did clean up the sigal a little bit.

all PG amps up to the end of the ZX/ti stuff would accept the 8 volt signal. They will love it. Just b sure to watch the sens when setting them
