sodfamily Posted September 18, 2009 Report Share Posted September 18, 2009 Ok guys riddle me this.. The other night I was out on the highway doing about 74mph, cruise control set and hammering the hell out of the subs. When all of the sudden it seemed like my car was pausing on hug bass notes. Didn't know what it was at first so I turned it down and started to listen to the engine for noises and heard nothing out of the norm. Cranked it back up and it started to do it again. I have been wounding what the hell it could be and came up with these idea's. 1) the bass was hitting so hard and trying to draw so much current it just dropped the electrical down and the car was dragging ass..(but my volt meter never falls under 13v even on huge bass runs). 2) the bass is effecting my fuel lines, pumps, injectors or anything fuel related. 3) And this is the one I think it may be. I am hitting so hard that I am breaking the sound barrier... :lol: Can anyone tell me what is happening. or Tell me if this has happened to them.

Loudcav Posted September 18, 2009 Report Share Posted September 18, 2009 its probably drawing so much current that when the spark plug goes to hit its got a weaker spark perhaps its dropping so fast that the meter cant catch it or your eyes cant see it Link to comment Share on other sites More sharing options...
basshead4life Posted September 19, 2009 Report Share Posted September 19, 2009 it could be a really good alt that holds high voltage on big loads and the load is just putting strain on the engine making it strain a little Team S.M.D. Maritime Car Audio- (2) 18" SSA ZCON D1 - American Bass 500.1 - 60 ft of 3/0 -480 Ah of battery - (2) stock alternators (70 +90) - Kenwood Excelon x-794, 4v preouts car audio is just a LOT more complicated than "this amp does this power" or "this sub will be this loud". its like 2 + 2 = banana. (if that confuses you then you get the point) lol Link to comment Share on other sites More sharing options...
CFAIST Posted September 19, 2009 Report Share Posted September 19, 2009 My Old Mustang GT used to do it after I put on the underdrive pulleys. It's drawing so much from your electrical system that it's causing a Missfire. But like it was previously stated, Spark happens fast. so you may not be able to catch it. I know when voltage gets low enough on cars that don't have systems they Missfire, the doors lock and unlock and the lights act funny. C.A.R.

CR Boom Posted October 1, 2009 Report Share Posted October 1, 2009 It is the load that it takes to spin the alt under load..... Think about this, a 7000 watt generator take saround 12-13 horse power to spin,..... 2007 Great Wall So Cool 4-12' RE audio MX's Stetsom 7k2D 6-Batts 3-Mechman 250 amp Rhino's Link to comment Share on other sites More sharing options...
