  1. Tony Candela of CE Auto Electric Supply, Juan Rodriguez and I decided to do some testing with the AD-1 Amplifier Dyno to see what effects adding a capacitor to your system does. We did over 60 Dyno pulls with a Rockford T2500-1bdcp, without a capacitor, with a 1 Farad electrolytic capacitor (a real 1 F), and a 100 Farad carbon supercap. Test vehicle is a 2013 Jeep Grand Cherokee, 5.7 Hemi, 180 amp alternator, single group 49 AGM battery, all wiring 1/0 AWG copper. We tested each possible combination 3 times just to make sure our numbers were consistent, which they were. Video part 1 is continuous power testing, video 2 is dynamic burst power testing. Enjoy!!! Video part 1= Continuous power testing (uncertified dyno test mode). We do 4, 2 and 1 ohm dyno runs with no cap, 1 F cap, and 100 F cap. All tests in this video were made using the Uncertified Dyno Mode which is a continuous sine wave. We test a Rockford T2500-1bdcp in car, with no added capacitors, then with a 1 Farad aluminum electrolytic capacitor added, and then with a 100 Farad carbon supercapacitor added. RESULTS: No Capacitor: 1499 Watts RMS @ 13.07V into 4 ohms 2059 Watts RMS @ 11.84V into 2 ohms 2366 Watts RMS @ 10.83V into 1 ohm With 1 Farad Capacitor: 1489 Watts RMS @ 13.10V into 4 ohms 2024 Watts RMS @ 11.90V into 2 ohms 2358 Watts RMS @ 10.87V into 1 ohm With 100 Farad carbon supercapacitor: 1531 Watts RMS @ 13.13V into 4 ohms 2208 Watts RMS @ 12.25V into 2 ohms 2606 Watts RMS @ 11.30V into 1 ohm Engine RPM held between 2200-2500 for all tests. 1F capacitor didn't add any power on the continuous RMS test, actually lost a few watts probably due to the increased number of wire connections. 100F capacitor added more than 10% more power on the continuous RMS test Make sure to watch part 2, dynamic power testing (burst power). Hint: The results are different! --------------------------------------------------------------------------------------------------------------------------------------------------------- Video part 2= Dynamic burst testing (Dynamic Power Dyno Mode). We do 4, 2 and 1 ohm dyno runs with no cap, 1 F cap, and 100F cap. All tests in this video were made using the Dynamic Power (Burst) Dyno mode which is representative of musical peaks. We test a Rockford T2500-1bdcp in car, with no added capacitors, then with a 1 Farad aluminum electrolytic capacitor added, and then with a 100 Farad carbon supercapacitor added. RESULTS: No Capacitor: 1543 Watts RMS @ 13.80V into 4 ohms 2550 Watts RMS @ 13.32V into 2 ohms 3154 Watts RMS @ 12.76V into 1 ohm With 1 Farad Capacitor: 1613 Watts RMS @ 13.98V into 4 ohms 2666 Watts RMS @ 13.60V into 2 ohms 3426 Watts RMS @ 13.35V into 1 ohm With 100 Farad carbon supercapacitor: 1620 Watts RMS @ 13.95V into 4 ohms 2616 Watts RMS @ 13.65V into 2 ohms 3260 Watts RMS @ 12.91V into 1 ohm Engine RPM held between 2200-2500 for all tests. 1F capacitor didn't add any power on the continuous RMS test, but it OWNED the Dynamic Burst testing!! 100F capacitor added more than 10% more power on the continuous RMS test, but less than 5% on the dynamic burst test.
