sure do buddy, I ran into a strange problem today. while doing some small testing... I played a 30Hz sine wave just to get the subs moving a bit, and I saw something very strange.. the 2 sub closest to the door were moving fine but.....the 2 closest to the port were barely moving at all, the bottom one was moving a bit but I think it was from the air in the box, the top sub wasn't moving at all!! I'm using only 8 amps now so 1 per coil.
I checked the wiring.. everything seems to be connected right. traced it back to the amps.. connected right. Amps were on, the protect light was off. all seemed good. WTF??
any ideas what I could have done wrong or missed?

Your saying you have 8 amps, so i guess they are strapped? If so you have 2 strapped amps per woofer, check and recheck how you strapped your amps, try changing the rca's from one to another, check if you have your master/slave configuration well.

Thats way way below tuning, say hello unloaded subs, ripped surrounds, folded cones lol
And the reason youve got two subs move and two not move is something you will have to learn to overcome. Its a fact off your box, the two furthest from the port will load differently to the nearest ones.

No, he has 8 amps, 4 subs, 8 coils. So 1 amp per coil, not strapped.
And dont use the master/slave function to set the amps, ever.

His amps are strapped, look at his pictures a few pages ago. He used the maxxlink, 4+ and 4- outs, and y-splitters i believe.

D-Bass: My amps are not strapped,strapping them would take each amp to .35 . don't want to go that low for testing and tuning. I talked to my buddy and he told me to check my maxx-link setup. I should be using all the A channels and none of the B's. I may have to Y-split off the Y-splits to keep all the amps on the A channel. I'll take some pics tomorrow to show you the setup I have now.
As for the 30Hz, it was just to see if I they were moving or not.. TRUST ME I did not go above volume level 4!

i thought i saw you'd connected the negatives between amps. Wasn't there a debate on using 12ga vs. 8ga. I think Sinister-David was talking on that subject

also, check the power output of each amp and make sure you just don't have the maxxlink turned down on those 4 amps.
Take your multi meter, set it on A/C volts.
Then touch the positive and negative speaker leads with it, do this on each amp and write down the output, if 2 or 4 amps have a MAJOR difference, then you know what the problem is

X100????? I Remember telling him to upgrade the links between amps to 8ga, sinister-david told him to upgrade the speaker wire.

Well, that part was solved, everything now is 8ga so I'm running 8 amps now. all are set to master, all strapping wires have been removed, each amp is connected to one coil. here are the pics of the connection to the maxx-link something tells me this is not correct Full shot.

Gavin, from the diagram you are showing, you are using the + and - ouputs of the maxxlink. This is NOT correct. Only use the + outputs when running the amplifiers unstrapped. Running them in the fashion that you have shown will cause severe cancellation due to opposite phases from + and - outputs. If you are connecting a + phase to one coil and a - phase to the other, you will smoke the amps, maxxlink and coils. Please only use the + outputs when providing signal to multiple amplifiers unlinked.

I would get rid of the Maxxlink UNTIL you have stuff figured out with your amps and everything else. Solder up an RCA distribution block or buy one then go from there. When I hooked up the Maxxlink I used last year it took me awhile to get it setup right (even after emails with the Maxxsonics guys).
Since I knew my score w/out it then I had something to shoot for with it in.
It is just one thing to take out of the equation of tuning your setup that has numerous adjustments. I say simplify it at first.

I have no idea how the Maxx Link works but I guess without using it for strapping its just a line driver, which you dont need.
Take it out, make a splitter box or buy a bunch more splitters.

The Maxxlink is cake to set up. He can Match the VAC output on each amplifier, use the Maxxlink output + A, B, C and D, then Y split from each of those to the inputs of each amplifier. No need for an RCA junction box and the Maxxlink serves as Y splitters. How much easier can it be to know that you can set the output of 8 amplifiers, then control everything from the Maxxlink and one remote Gain control. I think you guys are making the Maxxlink seem a bit harder than it is. It is the best RCA junction/Y splitter on the market.
Gavin, email me with specific questions and we can speed the process up a bit.

Less adjustments = easier to figure everything out. It took me a good 25 burps to get the same score with the Maxxlink then without and thats with everything hooked up right and just messing with the little knobs.

Hmmm. I dont know about this set up thing.. I had the same prob. trying to hook up right. Did not pay with it that much but, its not so easy when you are not fam. with hooking up so many amps.
