Passive to Active questions *Newbie here*

[xravexboix 10+ year member]

Hi,

I'm currently running:

Eclipse 8454 (Pro)

Eclipse DA7122 (1 Ch)

Eclipse Aluminum 10" (x2)

Eclipse PA5422 (4 Ch)

DA HEX S600s (x2, yes flame me lol) Passive

I got a deep discount for Eclipse.

Anyhow,

I want to switch over to an Active setup (probably in 2 weeks since I'll finally have a weekend off). I'll just be using the XO from the source unit since it's enough for non-comp use. I just wanted to make sure I had all my info correct prior to proceeding.

Headunit Low Pass -> DA7122 -> Subs stays the same. No changes needed

Headunit Mid -> PA5422 REAR -> 6.5" Speakers

Headunit High -> PA5422 FRONT -> Tweeters

Now, for the info so I don't blow everything up... the Hex are rated as 120w RMS @ 4 ohms (mid) and 90w RMS @ 8 ohms(silk tweeter). (Info: http://www.diamondaudio.com/products/pdfs/HEX_Manual_A5.pdf)

My 4Ch amp is rated to run at [85w RMS @ 4 ohms] or [120w RMS @ 2 ohms] (assuming 13.8V in both).

Is it possible to connect everything to run @ 2 ohms (how to wire?) or should be just ran @ 4 ohms (how to wire the tweeters?).

As stated, I'm a supernewb. I will be removing the 2nd set of HEX and just have them laying around just in case.

All input and criticisms welcome =D

you cant run a 4 ohm speaker to 2 ohms without another 4 ohms speaker wired in parallell.

just wire it up you had planned in the beginning. it'll be plenty of power for you.. make sure to keep the gains low on the tweeter side though.

Yea, I know you have to wire 4 + 4 to get 2 ohms. I may end up doing that now.

Is it possible (on any 4 Ch amp) to run the front at 4 OHMS ( 8 + 8 on each side w/ tweeters) and run 2 ohms (4 + 4 w/ the mid drivers) ? Someone on another forum suggested that, but it sounds like it'd end up blowing something up lol

Thanks again.
