Bummer, anyone else know anything about the RSDC's or wanna shed some light on WHY its so **** hard to get my amp to output 1000w truly..

you running 2 ohms or 1 ohms on the amp?

no, it really doesn't make a huge difference, although you can tell whether it is on or off.

I always thought subsonic filter filtered what went into the amp, and since bass notes are 80 hz and below u set it there meaning nothing above eighty the amp reproduces.

1 ohms on the amp..

no

1 ohms on the amp..

are you positive? And exactly how are you measuring watts?

no

So how do you set it then?

i think your thinking of the low pass filter?

slightly below the tuning of your enclosure

I measured the watts with a combination of a DMM on the amp and a Clamp meter on the speaker wire from the sub.

Amps x Ac volts = watts

so 18 amps x 40.1 volts = 720 peak watts take that x .707 (efficiency of amp) and i get 510w RMS

Also positive on the ohm.. Wired it Neg to Neg Pos to Pos and Pos to amp Neg to amp.

you're thinking of the low pass filter.

a sub sonic filter is a high pass filter meant to keep inaudible frequencies to a minimum.

That's why. Put the clamp on the power wire from the batt

Also there's not much below 35 hz or so in music anyway. The natural roll off of the box will suffice as a ss filter imo.

I cant clamp DC current, i can just measure the ac current from the sub to the amp.

it definitely makes a difference on my amp.

Made a difference to me, it was like driving a car without holding on to the steering wheel.. Now it feels like i have both hands on it..

Doesn't hit the lows wildly.
