SD GZ Setup Help
I have a Sony ax5000 HU, RF DSR1, SD 1200.4-4 GZ yellow baskets in the front and SPL 6x9 in the bags.
I have them connected to all four channels separately and the volume is underwhelming. How are you guys running these GZ’s ?
Gain voltage? Crossover, HP or Band and where to start? Thanks for any help you can offer.

I'm pushing more like 300w each to my two pairs of GZ's, crossed at 75hz. Sound great. I don't however need to run them past 1/2 or one bar past. Plenty loud enough. The issue with the 4 Ohm version with 4 speakers is, you can only get around 210w real world max.

so you’re running them Bridged on the 2ohm? Could I run the GZ parallel, Bridged to get 600 watts to the pair, is that possible?

They dont need more watts. 200 to 250 each is plenty. They'll still get plenty loud enough as well. The more wattage you send them, the higher your crossovers need to be to make those speakers last.

Ken - In theory, you could try it, however I have never tried it with dissimilar speakers so I hesitate to comment. Perhaps there are others out there who have tried this successfully (or not) who can chime in. Seeing you don't have to change much to test it, I would give it a try and proceed cautiously. My one concern would be the high cut to accommodate the GZ's might be too high for the SPL's. I've never ran the SPL so I'm not real sure of the best settings with these guys.
I ran into the same scenario with my last build with a SD800.4 4-Ohm, and during my upgrade this time, determined that the 2-Ohm provided a better solution for my needs, and of course I wanted more power. Eventually I'll be running the rears off the SD800 bridged at 400w ea, if I don't bump to a SD2400
My .02 fwiw.

Teed - The OP specifically stated that he's underwhelmed with the volume at 200ea to 210w ea, which IS on the light side for these speakers at 93db. So, you are suggesting that he just be happy and move on, when we have plenty of folks running 250w to 300w with no issues? I already tempered that by saying I don't push it hard with this much power and I agree that you have to use some common sense, but these speakers have proven to be pretty durable once properly dialed in - which is the key with the longevity with any speakers. Granted there have been reports of folks having cutout issues with the GZ more recently, but that seems to be isolated to specific lots, and the OP hasn't reported any such issues.

Now perhaps he's incorrectly reading how many watts he's pushing them? I know when I did my bike, I set gains where I thought was one number, but when I went back it was a different reading. Had to do with the gain pots on the pac I was using. I have those all the way open now and didnt need to even crack my amp gains at all to get my desired wattage.

Yeah, goes without saying that he needs to confirm the gains and the DSP are set correctly, and certainly proceed with caution.

I wasn't suggesting he be happy with speakers he cant hear. I personally know ppl that are running them at 200 watts and they're plenty loud. But what I was suggesting is, 300 watts per speaker, you probably shouldn't be crossing them that low. More power means more chance to distort and blow them. And the lower crossover, with that much power is asking for trouble.
Now perhaps he's incorrectly reading how many watts he's pushing them? I know when I did my bike, I set gains where I thought was one number, but when I went back it was a different reading. Had to do with the gain pots on the pac I was using. I have those all the way open now and didnt need to even crack my amp gains at all to get my desired wattage.
