I ordered Mmats Hifi6150D & M2000.2, to replace the Zapco STs... I also have a Mosconi Pico 2 that is currently powering the AF GB25s for rear fill. Front stage is GB10s and GS690s.

6150:
6 x 150 Watts RMS @ 4 ohms

Pico 2
2 x 80 Watts RMS @ 4 ohm


Option A.
Simplify my system by getting rid of the Pico and using the 6 channel for 2 way plus rear fill (giving each driver 150 watts).

Option B.
Complicating everything by going from 2 way to 3 way and powering the front stage with the 6 channel, then getting another pair of GB25s for rear fill using the Pico.

Option C.
Using the 6 channel for the tweeters and 690s only, and bridging channels to give the 690s 300 watts each. Keep the Pico to power the GB25s for rear fill.


I am leaning toward option A, but I'd appreciate some feedback and/or more better ideas. :)



P.S. I can't wait to give the GB12s 2,000 watts and see what they can do!!!

I have the mmats 1400.2 on 2 gb12s at half gain and half to 3/4 on the director and they over power my front stage hardcore. That 2000.2 will be nice. Are you still having issues with tuning your helix. In my opinion you should scratch rear fill and go with 3 way front on the 6150 with your gb25.

Option D...

run 3 way up front off the 6 channel, and replace the GB25's in the rear with something a little more full range for the rear and run that off the Pico.

Awesome! I got the 2000.2 for the extra power, but also because it's the exact same size as the Hifi6150... Symmetry. OCD.

I have gotten the hang of some of it now, so it's not so much having issues tuning with the Helix, it's this weird distortion I am getting on certain songs... Actually, I have a really good sounding tune right now.

Thanks!

Two votes for a 3way in my Jeep (my wife's gonna be mad at you guys, lol)!!

I don't mind having a second set of GB25s in the D panels, as they fit perfectly and look factory.

Those do look sick. I'm all for having rear fill but from what I have read it can be a royal pain to tune with flipping left and right signal and all the other things you have to do to execute it properly without ruining your front stage

I already have it set up and tuned properly in the Helix, and it sounds great!

I'd do Option A for the sake of simplicity. I know what the gs690's will do on 150+ each so output shouldn't be an issue. And the gb25's are fine for the bandwidth you run rearfill. You only want them playing roughly 300-4000 give or take a little on each end.

3way up front, to hell with rear fill! I’d rather invest rear fill $ into mid bass...

..GB60?
You ever run rears PROPERLY tuned? It works quite well in the d-pillar locations of a Grand Cherokee. Me and David both have first-hand experience with those locations;)And don't see the benefit of replacing a perfectly good midbass driver with the cone area of an 8" with a 6.5" midbass that now costs $900 for a pair. While quite nice I don't see the benefit of them unless that's all you can fit.

I'm on your side with ditching the rears, but I don't see any benefit in ditching the 6x9 in favor of a 6.5".

If David has already got the rear fill dialed in, and he likes it, then I doubt he'd ditch it. I personally wouldn't waste the amp channels on rears, but when it's done well plenty of people like it.

When you walk back in the house please loudly say you really want to try a 3 way in your Jeep!!

Can you fit 2 low profile boxes under the front seats??
My wife actually saw my signature a couple years ago... She didn't think it was quite as funny as I do! :p

You're right. I have the rear fill dialed in and I really enjoy it. It's subtle, but does add an interesting element to the sound. Plus, if I was to pull the rears that would leave holes in the D pillars...


So it sounds like the consensus is step up to a 3 way with GB25s... I realize the GB10s are better suited for that anyways. I'll leave the little Pico and the rear fill alone for now and just plan on adding a second pair of GB25s to the front.

The other option that I forgot to mention would be selling my GB10s and getting GB15s and staying with a 2way... Then I could sell the Pico and run everything off of the Mmats amp. The only thing I don't like about that option is having to hack up the factory tweeter location, as I am trying to sell this Jeep and get a Trackhawk.

Decisions, decisions...

I wouldn't put any more real work into this Jeep if you're trying to sell it.
I agree. At least not waste time and resources doing anything custom or install related...
All of the equipment will be transferred to the new one, IF I don't sell it with the audio included (which doesn't seem likely). That's why I am moving forward and getting things that I want/need for now AND later.
