Which setting on volt meter?

[Tek18 10+ year member]

Here is my volt meter i am borrowing from a friend as i cannot find mine >.>

i used the 200 for ohms and it read out .8-1.1 on my speaker terminal so i think thats for my speaker but i don't want to blow out anything...

which one should i use for:

A. Testing the battery voltage

B. Testing the 2 wires in the back of my car voltage ( and should this be any different from battery voltage? i would guess a little.. )

C. testing my amp voltage when setting to ~31.5V on the speaker output

D. setting the subsonic etc.

not sure which one / on the amp which holes to use the amp power or speaker etc.

Thanks

For a and b set it at 20 vdc. For c and d use 200 vac but prob won't be near as accurate. When using a manual multimeter start with the largest number then switch down until a more appropriate reading is attained. If you start too low you may pop the fuse in the meter.

yep i have a meter just like that one.

thanks, the 20vdc worked great.

200vac is what i use for setting the voltage on my amp? how do i set subsonic and such

Under amplifiers check the sticky for amp setting. Look at page 42. It mentions how to set the filter. What is your box tuned to?

box is tuned to 32hz, and page 42? what?

just downloaded a 50hz tone and a 32hz tone for setting the amp, i will use the 50hz on repeat, but the 32hz with the woofer just to see what it sounds like first time on //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Look under the amplifier section. There's a sticky about setting the gain or general setting. It's the one with a lot of pages. Look at page 42.

I was tuned at 31 hz and had my subsonic set at 25 hz. I played fine down to 26 hz but started getting ehh from 25 hz and lower.

On your tone I first used a 0 db tone and it didn't work for me cause I listen to rock and country as well as rap. I use a remote level with my amp for the differences but a hu with a subwoofer level would work too.

Box tuning alone doesn't tell you what to set your subsonic to as what you need is cutoff frequency.
