Colin - STAPUFT Posted September 16, 2013 Report Share Posted September 16, 2013 Now that is an extensive set of tests! And what a battery bank to back it all up.

Purplehaze Posted September 16, 2013 Report Share Posted September 16, 2013 (edited) Don't really understand the 5K #'s at all. Why did the voltage go so low on the un-certified? And the output dropped as well? 6K + on certified, but why would the un-certified get lower?

tacomaguy1 Posted September 16, 2013 Report Share Posted September 16, 2013 I am going to retest the 3.5k and 7.5k once I receive my toolmaker dual 2/0 inputs for SHCA wire. I have a theory that I want to test and have the ability to with the dyno. I am going to test single 1/0 input vs single 2/0 input vs dual 1/0 input vs dual 2/0 input. What I am looking to find is what the difference in power output is and find out what the proper way to wire up each amp is to get the most power from it. I have had people ask me to wire the amps up just using the single power and ground or dual power and ground in the case of the 5k and 7.5k. My response to that is, if you are going to spend $500-$1000-$2000+ on an amplifier, why are you going to cheap out an not buy a couple of $30-$40 sets of dual inputs and a few more feet of wire to properly feed your amp? That is like buying a lamborghini and running 87 octane through it because it is $.50 cheaper. But if the amp only comes with single or dual inputs then shouldn't that be enough and that's how it should be tested? Idk that's my way of thinking about it Quote Team Flex Issues Link to comment Share on other sites More sharing options...
CJ18 Posted September 16, 2013 Author Report Share Posted September 16, 2013 Don't really understand the 5K #'s at all. Why did the voltage go so low on the un-certified? And the output dropped as well? 6K + on certified, but why would the un-certified get lower? I am running tests back to back with very little time for the batteries to recover. That is why the drop down to 13.5 on the uncertified test. Ideally I would let the batteries sit for a few minutes between each test, but with so little time and so many tests to run, I just cant.

Idk that's my way of thinking about it Valid point and they will be tested that way as well. I am also going to show the absolute ideal situation and how to get the most power out of your amp. You cant exactly fit 6 power and 6 ground inputs on these bigger amps either. 3/3 is the most that will fit. Just because that is what is on the amp doesnt mean that that is all it needs to supply the amp with the current that it wants. I am going to order a roll of CCA 1/0 today to prove that point even further. 1 Quote Link to comment Share on other sites More sharing options...

I totally get that, but why then was the 7.5's uncertified #'s higher, even though the voltage was lower? Actually, every amp I've seen tested has gotten more power from un-certified mode. I'm not really concerned with the voltage as much as I am the output #'s. That wasn't that much voltage drop.. Just don't see how the "un-certified" mode would get weaker. And on this amp only. Not trying to argue or start shit, just really don't understand those results. I think that # should be over 6K, if the certified is over 6K. See what I'm getting at? 1 Quote Kickin' Cruiser Seller Feedback Stage 3 Dash, Door Panels,4th Order wall 4 - 15'son a DC 5.0K 2 DC 5.0K'sSolo X 15 (v.2) Sub Build Link to comment Share on other sites More sharing options...
TeamHT Posted September 16, 2013 Report Share Posted September 16, 2013 I'm in for the 5k at .5 haha. Don't get too excited Kasey, now you know you have a real beast of an amp Quote Tell me...does this smell like chloroform to you? Link to comment Share on other sites More sharing options...
