Mack187Murder Posted June 3, 2018 Author Report Share Posted June 3, 2018 Still.......my biggest question........Wondering if anyone has an answer for. how do I figure out the increments on a the dials of this amp. Which isshown in the original picture. When theres only.a high and low number given. And no increments or marks between . Link to comment Share on other sites More sharing options...
Crazy 8s Drums Posted June 3, 2018 Report Share Posted June 3, 2018 You can take the value on the farthest counterclockwise turn and the value on the clockwise endpoint, calculate the middle point and mark the middle point on the amp, basically at the 12:00 position. Continue dividing the circle similarly and you will get approximations. of the values at that point. The marks are just approximations anyway.

reedal Posted June 3, 2018 Report Share Posted June 3, 2018 You don’t figure it out, because those numbers are useless because no two potentiometers are the same. The SMD Tool amp is in my signature. Try to find someone close to you and see if you guys can meet up so you’re not wasting your money risking your equipment with guesswork.

Kyblack76 Posted June 3, 2018 Report Share Posted June 3, 2018 Put same meter on output. Play whatever tone your looking for. 60hz, whatever, dial nob down, when voltage pieces out, theres kinda 60hz. Amp probably has a 12db slope, so figure a little lower than that, is kinda true 60hz.

Mack187Murder Posted June 3, 2018 Author Report Share Posted June 3, 2018 Very good. And lastly. Trying to hook these RCA cables up. But there no plus minus or red black on the amp. Just the same colour white with the letters A under one and B under the other. I'm assuming A is plus and B is negative? . Link to comment Share on other sites More sharing options...
Crazy 8s Drums Posted June 3, 2018 Report Share Posted June 3, 2018 RCA cables are positive inner pin, negative outer ring. On a mono amp it doesnt matter which is right or left. (A pair of RCAs will be r and l, not pos and neg.) Orion XTR amplifiers Skar subs Link to comment Share on other sites More sharing options...

Mack187Murder Posted June 4, 2018 Author Report Share Posted June 4, 2018 So I tried the dmm.method Made sure all.db we're set.to 0. No bass boost etc Turned my head unit volume to 75% (Max is 35 so 75% of 35 is 26) Unplugged.my.positive.speaker.wire.from the amp Had a 40-60hz sinewave on repeat 4500watt amp at 1ohm Then took the square root.of 4500 to get my.voltage which was 67 Set my.dmm.to ac voltage Hooked.it.up to the speaker.terminals. instantly.showed like. 2.7 for voltage Turned up.my.gain on amp till it hit 67 at its peak (On the amp to hit 67 voltage my gain is up 3/4 or 75% on the dial Hooked everything back up an played a track. Didn't get my head unit volume past 14 and my truck sounded like it was gonna fall apart. I couldn't even hear.my mid range . So I turned.my gain down.on my sub amp to 1/3 and cranked my head unit up.to 32. Shit sounded wicked. Bass was tight. Mid range was clear. Shit pounded.. So what the fuck.did I do wrong the first.time. My.dmm.is worth a grand This is what it read when i turned the gain up to my.desired voltage But something was extremely.wrong .
