I Need Help..........

ok...my next dumb question.....how do i check that...

using a test tone for the paticular speaker put your player on repeat and then use your voltmeter using ac voltage on the rca output of your headunit inside pin is + outside ring is - play the test tone at listening volume and get a reading from it. you should test it listening volume cause they will usually fluctuate to less voltage at lower volumes. panasonic is good for not listing that and typically they are 2-2.5 on their units...

thanks chris..

Now my next question...I might as well continue learning here...........

This is the cheapo miltimeter i have...(it was given to me) and guess what... Ive Never even learned how to use it..

where should the settings be....to set my amp gain voltage..

also where would I set it,,,to check voltage in general...

ha dont feel bad ive been playing for years and just learned how to use one of them there fancy volt finding thingymabobs

Throw just a drop of clear silicone on one side of the cup and it will keep them from vibrating loose bro....and you can still remove them if necessary

according to that..........my gains should be set @ 54.8 volts....on the 1500s they are all dead on 54.8 but the bass seams really ...well ..not enough......untill the volume is at damn near full tilt... I set the gains with a 50Hz note...

I hear that... I made a post on the roe forum about their calculator which is the same as the one on subwoofertools.

My amp is a SPL Dynamics EXT-3000D.

Amp specs.

1 x 1000W @ 4 ohm @ 13.8V

1 x 2000W @ 2 ohm @ 13.8V

1 x 3000W @ 1 ohm @ 13.8V

1 x 4500W @ 1 ohm @ 16.5V

1 x 9000w @ 2 ohm strapped @ 13.8V

So when I set my gain too 54.8 volts using a 50hz, 55hz, and a 60hz test tone I couldnt get shit for power out of my amp. I used a really expensive Bluepoint dmm that my buddy bought from Snap on. My head unit is a Alpine CDA-9833 with 4 volt preamp outs, I had my fader and balance in the middle, my subwoofer volume at 8 and my volume at 28, with bass, treble, and midrange at 0.

Where I had set my gain on the amp according to my dmm was way too low, it was barly up. It was less barly up passed the 6 volt mark on my amp, and 6 volt is the lowest my amp goes, and goes up 0.2 volts. So common sense would tell me that half way up is around 3 volts, and a little below half way up would be 4 volts. So I pretty much used my ear, and not the dmm because I felt that the calculators where misleading. And I know I dont have a cheap or underrated amp.......

You can kinda make out the readings on the amp but its from my cell phone cuz my digial is broken

This is where my dmm told me too put my gain about at 54.8 volts

Here is where I ended up putting my gain.

so you put your gain all the way up? thats not smart.
