Thanks! I will use these Rs until I get all of the electrical finished, then I will replace them with something bigger, and get another 2000.1. I am very impressed with that amp so far. I have looked for a good CRX for a long long time now. Finally found this one in Memphis, TN a couple weeks...
I am speaking from experience. Over 20 years of experience in the car audio industry. I see people flaming the type-r because of the 2 inch coil they use, it makes them look silly because coil size is not a factor in getting loud...
The proliferation of custom built subs is not what got the spl...
Two Rs in a properly tuned enclosure will be very loud. I can tell you that moving from 2 stroker 15s (old school) on an Orion 2500D @ 1 ohm was only .5 dB up from 3 R 12s on the same amp @ same load. With more power, however, the strokers would have walked them.
Setting gains with DMM = waste of time.
Set everything to level, and turn gain on amp all the way down. Cue up that 50 cycle tone, put volume knob on cd player to 95% of full volume, then slowly adjust amp gain up until you hear distortion = done.
