-Resistance is NOT Impedance. -Volts * Amps does NOT equal Watts in AC land -You can NOT use an AC voltmeter and AC current meter to get true power unless you are powering a resistor and are using a scope or clipping detection device. I don't care what your friend the "electrician" said. -You can NOT use a DMM to measure impedance -Clipping is NOT DC -There is NO SUCH THING as Watts RMS (though we use it in audio) -WTH is "Box Rise" -The word "subsonic" to describe low frequency audio is TOTALLY incorrect -CCA wire is NOT OK -Class D is not better, it's cheaper WTH is Class D?

We've got the AD-1 Amp Dyno very close to production trim. Here are a couple of demo videos showing some of it's capabilities. Currently the AD-1 Amplifier Dyno is the only self contained test system that can measure RMS Continuous Power and Dynamic Power of both Full Range and Bandwidth Limited (subwoofer) Amplifiers in the world....and it does it in YOUR CAR! Please enjoy these two videos. The first video demonstrates the gain setting capability of the newly developed DD-1+ technology built into the AD-1. DD-1+ allow the user to make variable gain overlap settings in 1dB increments, e

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 c

The D'Amore Engineering AF subwoofer line is shipping now! Just in time for the holiday. We are running Black Friday Week starting tonight at 8pm. These are single 4 ohm coil, LOW Bass in a small enclosure, very low distortion, VERY musical subwoofers. The coils are around 3.5 ohms making them great for a single woofer on a single Class A/B amp bridged, or a 3 or 4 subwoofer system on a 1 ohm stable mono amplifier. EVERY single one of these is fully tested before they leave here and come with the ACTUAL T/S parameters for that specific woofer!!! An industry first? Take a look at them

Just a quick video to demonstrate one more use of the IM-SG. Everyday it seems we find something around here that the IM-SG is useful for. Also, a new product from D'Amore Engineering in video! http://www.youtube.com/watch?v=844mCPYfKLE

So a few weekends ago, Juan and I drove his Altima over to CE Auto Electric Supply to install a Big 3 kit on his car. It is a 2010 Nissan Altima 3.5SR, stock electrical system (160A alternator), with (1) Rockford T1500-1bd loaded at 1 ohm, and (2) Rockford T600-2 amplifiers loaded at 4 ohms stereo. The T600-2s are modified to put out max power at 4 ohms and do around 325W/ch at 4 ohms. In total, around 2800W. <Rant mode on> Yes it is a capital "W", named after James Watt. Also, I didn't put "W RMS" as there is no such thing. <Rant mode off> We tested the battery and found it
