Toxiccasper Posted July 15, 2008 Report Share Posted July 15, 2008 How do you measure the RCA voltage at the end of my RCAs where they plug into the amp. Ive tried testing them many times but cant get any reading off of them? I put the DMM of AC right? Link to comment Share on other sites More sharing options...

Bass4Lyfe Posted August 4, 2008 Report Share Posted August 4, 2008 the pre-outs should be 2v 4v or 5v. maybe even 8 but it specifies in your manual for the Hu does it not? ~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...
TJ_Jeep Posted August 5, 2008 Report Share Posted August 5, 2008 i think you put it on AC?? because doesnt AC have signals idk Vehicle:1998 Jeep Wrangler 4.0 I6 with Cherry Bomb and Cold Air Intake, Speakers:5 1/4 Pioneers in front and back Deck: Jensen DVD In-Dash Amp: Lanzar Opti-Drive 2000w Subs: 2 Boss Chaos Edtion 1000w max (500wrms) Rubber: Nitto Grappler 35 x 12.50 Fun Things: Cobra CB with PA speaker to piss people off =] If the listening level is too loud, then your not deaf enough =] Link to comment Share on other sites More sharing options...
ISO Posted August 7, 2008 Report Share Posted August 7, 2008 How do you measure the RCA voltage at the end of my RCAs where they plug into the amp. Ive tried testing them many times but cant get any reading off of them? I put the DMM of AC right?plug your RCAs into the H/U, put in a test tone disc. Set the CD player to repeat and set the CD to the frequency track you want. Then set your volume were you think it should be.Radio is done Set the DMM to AC Voltage (ACV). Plug your test leads in normal. Now use the positive from the DMM on the center pin at the other end of the RCA. You must not touch the ground. PERIOD. Next take the negitive from the DMM and put it to the ground on the RCA. (The round metal circle that surrounds the center pin) A tip for ya is to make a positive DMM lead with a little alligator clip soldered on it. you can stick that to the center pin on the RCA and the regular negative tip in one hand and the RCA in the other. Make one for the Negative too as it comes in handy when working on cars and always need a ground. Isobaric - Refers to the practice of coupling two drivers together to make them act as one.

ISO Posted August 7, 2008 Report Share Posted August 7, 2008 Guys I meant to say AC Voltage, not AC Amperage. I fixed it up above so it is rite now. Sorry to everyone.

ISO Posted August 7, 2008 Report Share Posted August 7, 2008 Like I sayed above its real handy to have an alligator clip line for your DMM. So for the ones that don't know heres some pics. These are VERY EASY to make even if you can't solder. Isobaric - Refers to the practice of coupling two drivers together to make them act as one.

mike fallon Posted March 21, 2009 Report Share Posted March 21, 2009 If you want to know the actual voltage going to the amp then you have to make a test pack of resistors that match the input impedance of the amp. Most meter leads are around .2-.4 ohms and the amp is around 5000 ohms. Big difference Link to comment Share on other sites More sharing options...

Big difference i want to challenge this.. since the RCAs are a parallel circuit, the impedance of the amp shouldn't affect voltage.. same way you will always get 110V AC in your home no matter what devices you have plugged in.. the only difference would be in the current flowing through the RCA leads..
