VtecDomani Posted October 12, 2008 Report Share Posted October 12, 2008 (edited) watts divide volts = amps Edit: sorry formula without taking efficency (sp) into account Edited October 12, 2008 by VtecDomani Quote Head Unit: Pioneer DEH-P4050UB Subs: 2 Pioneer Premier 12" ts-w3004spls Sub box: 3.2ft3 tuned to 35hz Sub Amp: SoundMagus DK 1800 Speaker Amp: Rockford Fosgate 200a4 Bridged to fronts Front Speakers: DLS MS5A components 2 gauge power & ground Link to comment Share on other sites More sharing options...
wL<3bass Posted October 12, 2008 Report Share Posted October 12, 2008 the formula is Volt x Amps = Watts x % Efficiency Quote Vehicle: 1997 S10 Blazer 4dr 4X4 Exterior: Rear End Bagged, Black Grill, Lifted 2" Amplifiers: Rockford Fosgate T8004 & T10001bd Batteries: 2 Stinger SPV35, Kinetik HC2400 Electrical: Big 3, DC Power 290amp Alternator w/ MLA at 15.5v Enclosure: 4.2 ft³ @ 33Hz 84sq.in. of port (20sq.in. per cube) Headunit: Eclipse CD3200 w/ 80G iPod Mids/Highs: Rockford T152s (a-pillars), Rockford T162s (doors) Subwoofers: 1 15" Fi BL Fully Loaded Wire: All 1/0g Kicker Hyperflex My YouTube Videos My Fiberglass A-Pillar Build My "Seamless" Looking Box Build My DD1508 T-Line Bandpass Build "Seamless" w/ Acrylic Windows (for '05 TrailBlazer) My Stealth 8" Fiberglass Build (for '05 TrailBlazer) My Build For A Friend's '08 Cobalt 15" BL Sealed Off From The Trunk My feedback/references...

VtecDomani Posted October 12, 2008 Report Share Posted October 12, 2008 if your using an amp like rockford, it should say on the birthsheet, or if there is no birthsheet and your using a D class amp it should be around 70-85% or may say in the manual.
