tigolbity Posted June 21, 2010 Report Share Posted June 21, 2010 my amp has 5 fuses that are 40A each. 40 x 5 = 200A 200A x 13.5v = 2700 rms am i right? Link to comment Share on other sites More sharing options...
HHR Ed Posted June 21, 2010 Report Share Posted June 21, 2010 mmm, not really. To really know the output you have to measure the output. By your estimate, thats the max power it would CONSUME, if it were to blow. What amp? what ratings?

HHR Ed Posted June 21, 2010 Report Share Posted June 21, 2010 I'll expand a bit on what I was saying to spread more understanding. The fuses are there to protect the amp from drawing too much current in the event of failure. So under normal operation it will never draw as much current as the fuse is rated. Also, a 13.5v DC voltage reading may be your standing voltage, but what does it drop to when playing? You calculate using this voltage drop. It will drop significantly on weaker electrical systems. Of course, all of this tells us what kind of power the amp is drawing from your electrical system, not how the amp is performing. No amp is 100% efficient. Most good amps are between 50-80% efficient. So if at 50%, your amp may draw 2700w, but only put it 1350w. To know what your amp actually is putting out you need to measure the AC voltage coming out of the speaker wire, then use a clamp on meter to measure the AC current coming out of the speaker wire. Then multiply those 2.

HHR Ed Posted June 21, 2010 Report Share Posted June 21, 2010 its a power acoustik gothic series 5500d Just from experience, that amp is usually capable of about 2000w at 1ohm Ed Lester ShowtimeSPL Host Showtime Electronics Video MarketingMy old Build Loghttp://www.stevemead...08/#entry511451http://www.youtube.com/showtimespl 5 time dB Drag Finalist Last ride 2007 HHR, current dB 153.5 and bass race 149.4 dB. 153.0 dB on music New Ride, 2008 HHR SS.

korey_hofer Posted June 21, 2010 Report Share Posted June 21, 2010 yep just what ED said I was going to say no amp will be 100% efficient. I think the new DD amps are 85% and they do great power previously known as wenn_du_weinst aka fucking internet coward supreme. I talk shit on other forums like a little bitch and hope i don't get caught out on the street. Link to comment Share on other sites More sharing options...
