Bass4Lyfe Posted July 29, 2008 Report Share Posted July 29, 2008 (edited) I got my DMM all ready to go to set the output voltage (AC) to 34 for ~1200 wRMS @ 1 ohm .... The tutorial in the amp section here says to unhook the subwoofer and hook the DMM up right to the amp - and play a 50HZ test tone. Now, is this bad for the amp? To play music with no sub attatched? please advise Thanks Edited August 1, 2008 by Bass4Lyfe Quote ~Matthew 1998 Toyota Camry XLE V6 3L (1) ScyTek Astra 4000RS-2W-1 2-Way Remote Start Alarm with Shock and Proximity (1) 20% Tint All Around (Gately Audio) (1) 250 Amperage HO Alternator (1) Big 3 Done In 1/0 (2) Kinetik HC2400 Power Cell (1) Alpine IVA-D106 Receiver (1) Peripheral Video Bypass Device (4) Alpine SPS-17C2 Speakers (1) Alpine KCE-422i iPod Control Interface (4) Sheets Dynamat Extreme; for speakers (1) 10 Square Feet Hushmat (Trunk & Rear Deck) (4) DC Audio Level 4 15" D2 Subwoofer w/ Level 5 Coils (1) Wall Built By David, Tuned to 32 Hz (1) Rockford Fosgate T40001bd Amplifier (1) Stinger 1/0 Wiring (2 runs of + 2 runs of -) (1) Stinger Volt Meter Link to comment Share on other sites More sharing options...
roscoe1129 Posted July 29, 2008 Report Share Posted July 29, 2008 Not at all. while testing its refered to as being unloaded. One of the many steps to getting a clean unclipped signal while setting up with an O-scope.

assman Posted July 29, 2008 Report Share Posted July 29, 2008 just make sure the pos and neg of the speaker wire isnt touching anything or each other. Quote Assman IdustriesFear The DuckTeam Notoriously Loud Mafia Link to comment Share on other sites More sharing options...
roscoe1129 Posted July 29, 2008 Report Share Posted July 29, 2008 just make sure the pos and neg of the speaker wire isnt touching anything or each other. oooh good point Randy. I would just make sure to disconnect the speaker wire from the amp all together to save you from that issue!

MickyMcD Posted July 30, 2008 Report Share Posted July 30, 2008 You know, I thought it was perfectly safe too.... ...then 32 transistors turned to ash. Make it quick, your amplifier will love it. Make it long, well, your amplifier may or may not turn into fried circuit board platter. Depends on your protection circuitry. Mine wasn't even there (gooood QC on that one.)

Bass4Lyfe Posted August 1, 2008 Author Report Share Posted August 1, 2008 Update: OKay so I set the gains Wed morning. 34.0 volts AC, it was about 1/4 gain maybe less. I have since turned it up to just under 1/2 gains because I wanted it louder. I put an Amp-meter (uses the magnetic B field so you just put it aruond your power wire) and its taking in approx. 80 amps at almost full tilt (as fult tilt as i go with my voltage which isn't anywhere near actual full tilt) its 84% effecient (My T1K) so that means its about 7-800 watts output at 1 ohm, 12-12.5 volts. My question is - the T1k has a birth sheet at 1600 watts. If I wanted closer to 1400 wats versus the 7-800 i'm getting now, do I turnt he gain up to more like 3/4? I DON'T want to clip the amp but w/o an o scope how do i tell? hope this all made sense!

When i did my big amps, I had the test tone on pause with my remote in the trunk with me, I could hear the note being played through my amps circuits with no speakers attached, I didnt like it one bit and drove to a shop with a scope 30 minutes away.
