Care to elaborate? Call me and I will tell you what I saw in the different tests I ran.

try a 6" aero

I wouldnt worry so much about the size of the port as long as the port area(about 15in2 per ft3) is there. The only other way to make it not be as skinny would be to shorten it, but then to do that, you may run into some dead spots in the box. You want a nice smooth airflow out of the box.

For those of you who watch the entire video, there is a discount code at the end. Or if you want to just scroll to the end.

The amperage readings are not 100% accurate. The clamp is set on peak hold. So it reads the entire time the test is being run. The Dyno stops reading at clipping. The amp may still be putting out power into clipping and the clamp still reading current being drawn, but the dyno has stopped reading power at the point the clipping occurs. The only way to get a 100% accurate reading would to have a dcA clamp built into the dyno pulling that reading at the same exact time as it is pulling the rest of its readings. I would be willing to send my dyno back to D'Amore to be modded if something like this were ever able to be done. Wonder If it pulls the same or less on a dynamic run? The pure sine wave is definitely a lot of work for it. Clamp doesnt read fast enough to keep up with the sample rate of dynamic testing. Sold my last set that I had in stock. I am waiting for my next batch to be delivered.

I was using Sky High 1/0 for these tests.

Also in my first test, I was using all 14 batteries. With a solid electrical setup behind it, there was only a 2w difference in the bare copper being stuffed into the amp vs the 1/0 input. When I cut the bank in half to simulate a lesser, more realistic charging system that would be in a vehicle with a 3500w amp, that is when I got these results.

That one wasn't directed at you. I have had a lot of people question and out right tell me that they are useless because of "poor contact area". That was directed at them.

Ah, you need the 4/0 to 1/0

The 1/0 to 4ga may be different if used on a 1/0 input since the 4ga staub will have less contact area than the 1/0 to 1/0 does.

The single 1/0 will fit.

New video for you guys

Yes I took the first video down. I am uploading new footage to my computer now. MUCH more in depth testing.

I am redoing my video now. 3 tests 1- Bare copper wire 2- 1/0 amp input 3- DUal 1/0 amp input

Hmm you give me an idea and I can get it all in 1 video.

2w. I think I have a video on my phone, I will look and see. 2w is an insignificant difference to me though. I just re ran this test again. MUCH different result with a lesser battery bank.

I did the test with bare wire vs the input and there was a 2w difference. If that is significant enough for you to want to see, sorry, I dont feel like testing it. I will do the same test jsut to disprove the people that think using an input vs not using 1 makes a difference.

I dont feel like unhooking half of these batteries right now, but I suspect that with a lesser battery supply, the difference may be greater.

Remember this is just a bench test under ideal conditions with very good electrical, In vehicle may be completely different with a sub par electrical system.

I just finished testing a 3.5k with the purpose of seeing the difference if any in using a single bare copper shoved into the amp vs 1/0 amp input and Dual 1/0 inputs. I will be doing in vehicle SPL testing to see if there is a difference with these in an SPL test later. http://www.droppinhzcaraudio.com/

Everest 5k vs Planet Audio "5000"

To the best of my understanding it takes it to the point of clipping and not into clipping.

Do you solder anything "there"? or just mate together? Leads are soldered to coil leads and then soldered to the push terminals tabs. Only soldering on the subs.
