That is the peak AC voltage you want coming out of your speaker outputs on the amplifier at your highest played volume.

I used ohm law before i got the DD-1 and i was set to high on the gain, about two thickness of the blade tip of the small flathead screwdriver.

I just picked up a dd-1 and I love it already helped a few friends. Oh and chive on man!

Chive on, vulcan2000!

I know the CC-1 & IM-SG are next on my list.

The AMM-1 will be mine some day too!

Incase anyone is planning on buying a dd-1 use this coupon code for $10 off (SMDDD1) which brings the total down to $139.99 on wccaraudio.com

Ignore the bass boost setting on your amplifier, all it does it help create distortion. If you want more bass get a bigger or multiple subs

Awesome !

Question for the car audio dudes,

I have 2 Sundown X12 D2s(1250 watts rms)...At first I bought a SAZ-2500D, and planned to run both subs off that one amp, but now, I've decided to get (2) SAZ-1500D's and feed each sub its own amp...now do I strap the amps or run them seperately? Let me know if you need more info.

box specs 2.75 cubes per chamber, ported and tuned to 32 hz.

2 X12 D2's
2 Sundown 1500D's
1 yellow top under hood, 1 Optima Blue top in back
2 runs of 1/0 wiring
1 270 amp alt

I still have the SAZ-2500D, its unused but figured the 2 SAZ-1500D's would be better.

I would strap at 2 ohms unless you have access to a cc-1 (I think) so you can match the gains on both amps,

You might want to consider building a bigger battery reserve too

I would strap at a half ohm, but I like to live dangerously.

From my experience I'd run 1 ohm per amp gain matched. Strapping seems to be a hair quieter on the meter.

So hard to perfectly match gains and settings on 2 amps. Potential for cancellation between subs.

With the SMD CC-1 it would be easy, it has a gain matching mode built in to it.

Details start at 1:51
