The purpose of the gain is to match the signal volts RMS coming from the source (CD player, etc.) to the input of the amp for correct power matching and to prevent clipping (damage by over powering).

Here is a guide that will help you set the gain correctly

You'll need a multi-meter (AC voltmeter, $15 from Radio$hack), Microsoft Excel and a way to burn an audio CD from an MP3 (test tone included).

If you don't have Excel, You can downlaod OpenOffice by Java (SunMicro Systems) for free to read spweadsheets (and you thought spreadsheets were for business).

Set the LPF to just below the highest range of the frequency response of the subs. Meaning if the frequency response of the sub is 20-200Hz, set the LPF to about 180Hz


set the LPF to where the other speakers start off. example, if the speakers start at 150Hz, set the LPF to about 160Hz. This overlap (or crossover - where the term comes from) is the ideal setting.

Set the subsonic (infrasonic) filter to about the same as the lowest setting in the range of the frequency repsonse of the subs. Meaning about 20Hz if that's the lowest in the range (20 -200Hz as above, if applicable).

Don't set the Bass Boost above +2dB (if applicable).

Set the phase to 0 (if applicable).

Zanussi tempoline not working, son twisted nob mid cycle it then stopped and wouldn't drain. Now not doing anything! Any ideas? I assume its a error code flashing up

The first step of a dishwasher is a drain / rinse drain. I would turn the dishwasher off at the socket, turn the nob to the off position only turn this in a clock wise direction IE: the direction the nob would naturally move. Turn on back at the wall and start as you would normally. The dishwasher will empty the water out in its first step then should cycle through as normal.

Because even though your stereo is turned down the gain for the sub is set all the way up so it will still gain a small amount of signal. it is a flaw with some of the newer aftermarket stereos. try turning the nob until the thump stops then change the bass setting on your deck to compensate for the bass loss.

Refrigerator temperature was turned down to lowest number (1) and now the refrigerator will not come back on and chill inside when temp dial is increased to higher #'s. Light is on so it is plugged in.

Repalce the thermostate nob which has teeth to hold the nob in desired level. Due to constant usage of turning the nob it would have broken. Please replace the thermostate nob and do not change the setting on and often to avoid such situation. It wil take care of itself without turning it on our own.

The car is all wired the power is good the ground is good the amp work and i have the sub turned on with the nob but the sub doesn't work it has a 800w rms amp and two 400w rms subs mtx 7500

You could have the subs wired in the wrong ohm. It might be turning off the amp and check to make sure that you rca cables from the head unit to the amp are connected right.
