  1. Mechman 240a S series

    Sweet! Now to wait for that tax money to reach my account...

    Are you guys running 4kW without a lot of problems? For example, do your lights dim when you have it full tilt? I'm doing a rough n00b calculation here, 240 x 14.4 = 3456W so just curious.

    For now, I'll stick with my BRX1100.1D until I save up for a bigger amp. I'm sure I'll hear a big difference either way after that alt + wiring upgrade though! Unleash all 1100W at least!

    I plan to order myself a 240 amp Mechman S series alternator when my tax money comes in, along with a big 3 kit from them. This is all going into a 2002 Toyota Sienna van.

    I am so excited!!

    I am also going to get one of those 1/0 wiring kits for my amp, probably this one here: http://www.ebay.com/itm/Execution-Audio-Blue-1-0-AWG-0-ga-Gauge-Complete-Amp-Amplifier-Wire-Wiring-Kit-/111138341159?pt=US_Car_Audio_Video_Amplifier_Kits&hash=item19e05c8127

    Soooooooooo EXCITED!!!!!! :wacky:

    So let's say I get this alternator installed and working, along with the big 3 kit and the 1/0 amp wiring kit. What amp would you guys recommend? I run two SA-12s in a big ported box, about 5.2 cu ft and tuning at 30Hz. I am torn between a few amps like the AT1400.1D, SAZ-1200D, kinda in that range.

    I know with that alternator I could probably run up to 3000W, but problem is by the time I order everything I'd have no more $$ left for the amp (or I'd have to save up for a bit which kills me).

    Oh help me, kind experts :wacko:

  4. My DD-1 came with missing or wrong parts?

    Turn the subwoofer volume up as far as it goes, it reduces the preout voltage for your subwoofer channel when its turned down, which in return makes the signal weaker. So say of your radio has 4volt preouts, having the subwoofer volume at 0, your lucky to be sending a half volt of signal through your rca cords which is not enough voltage for the dd-1 to detect, but once connected to an amplifier (which amplifies that voltage hence the name amplifier, you see a signal). Numbers are just being used as an example.

    So turn subwoofer volume up all the way

    Than find max clean volume of the headunit, if its volume 35 of 35 with the sub woofer volume all the way up your done, than proceed to tuning the amp gain with the dd-1.

    If you are using the amp on the deck for your vocal speakers inside your car, you can also use the dd-1 to check the max volume of that amp by touching the dd-1 probes to the speaker outputs on the back of the radio (generally the radios internal amp will distort a lot sooner than the preouts of the radio and will yield a slightly lower max volume).

    So once you have the radios internal amp volume noted, than proceed to the rca outputs and the subwoofer volume, which would still be all the way up most likely.

    then move to the amp gain for your subwoofer.

    You will always want to tune your radios volume with the volume, and subwoofer volume as high as you can go without distorting prior to tuning the external amplifier(s).

    If for whatever reason you dont want your substage to always be so loud you just turn down the subwoofer volume, and then turn it back up when you please.

    Thanks, so I was doing it right on the part where I turn the subwoofer level all the way up from the head unit. I had it maxed out at +15. Since I wasn't able to get a signal directly off the head unit RCA, I tuned my headunit through my amp. Gain all the way down, crossover all the way up, subsonic filter all the way down. I distorted at 32/35 with Track 1, 40Hz -0dB.

    Now I shall crank my gain at volume 31 at head unit until the distortion lights up as well right? Thanks for all the info btw!

    OK, makes sense, the 1KHz shouldn't be detected through the amp. I was able to get a 40Hz through my amp after sticking my ground probe in with the ground 4 awg wire and the + speaker terminals. My head unit is kinda weird. It has a built in "subwoofer level" control and when I have that set as flat "0" it won't pick up a signal until it's cranked almost all the way up and even all the way up 35/35 it won't be anywhere close to distortion. I also have a bass knob for my amp.

    Hifonics BRX1100.1D amp

    Kenwood KDC-355U deck

    Direct RCA connection to deck still doesn't detect signal... connecting to amp however, does. I did the "measure headunit through amp" procedure and with my "subwoofer level" all the way up at +15 I distorted at 32/35... is this realistic?

    Not running a ground loop isolator. Just a cheap RCA cable. I finally got a signal after tinkering it around for a bit. But I had to turn my HU waaaaaaaay up to get it, like volume 20 out of 35 to see the 40Hz detect light up. With my HU set to everything flat, I maxed out my amp gain and volume at the same time and got no distortion (weak signal?)

    My 1KHz detect, however... never came up. Refused to detect that part regardless.

    Could it be a bad RCA?
