Need Some Help...

[HondaMan450R]

I just got a new 12'' Fi BL to go with my Rockford Fosgate T2000.1bd. I set the gain voltage to what the chart in the stickied post says to set it at, which is about 40 volts for a 1 ohm load.

When I hooked the sub back up to the amp and play music, the output seems to be low. It does not seem to be nearly as loud as it should be. The sub is hardly moving. I do not have any bass boost turned on. One way that I confirmed this is my voltage holds steady @ 14 with completely stock electrical and a 8 year old OEM alternator.

Someone please clue me in......WHAT AM I MISSING?

was you running the 50 hz test tone as well?

*whats the birth sheet say for your t2k?

[Team_DC-Derrick]

my rms chart for 2k rms at 1 ohm shows 44.72 volts...

I used a 30hz tone and I wanted to gain a little low because I know the T2000 is too much for a BL.

[Team_DC-Derrick]

well, the chart that i use says use a 50 hz tone, but you can adjust it to where you want

if you want the 2k to push out 1500 rms or so put it at 38.73

if you want it to put out 2k rms you want 44.72

or higher 2500 rms is 50 flat...but i do think its the 50 hz test tone that you need to use

so I guess my gain could be way too low because the amp may produce more voltage at 30hz than 50hz....I guess I'll try a 50hz tone then.

But is it okay if the voltage is higher than the chart suggests when I play a different tone?

[HondaMan450R]

should I make the tone amplified 100% when I create it on Audacity?

go to realmofexcursion.com (when it starts working again) and go to the downloads section, get a -3db 50hz tone and use that, tune your gain to 1500rms (or 1000rms if your alternator cant handle it, but try 1500 first) and your set.

An amp is supposed to produce the most at a 50hz tone or so i am told, and if you set your gains at 1500rms, its not gonna push 1500 the gain wont turn your power up or down, it just adjusts your input sensitivity from your headunit, so if the t2k is supposed to do 2k rms, then set the gains for 2k rms not 1500 or any other setting.
