brsteinbach Posted May 19, 2009 Report Posted May 19, 2009 Hey guys I searched but got nuthin. I was wonder If a class A/B amp was more power hungry then a class D amp. I think I seen someone post that somewhere. I was just wondering if it was true, because it would make sense because my amp makes my lights dim horribly and it's a class A/B amp. Oh and BTW they would obviously be the same watts at the same Ohm load. Thanks guys. 2 Infinity Reference 1252w 12s 4.2 cubic foot box tuned to 28hz Sub amp: 1 Profile AP1200 Speaker amp: 1 Sony Xplod XM-504z Kenwood eXcelon KDC-X492 4 and 8 Gauge Knu Big III In 1/0 All in my 90 Accord Diamonds are forever, but 9's end that shit fast....
VtecDomani Posted May 19, 2009 Report Posted May 19, 2009 They are much less effecient, so they draw more current to give your subs the same power as a d class could drawing less current.

BanginOnABudget Posted May 19, 2009 Report Posted May 19, 2009 i love them, 250 rms at 4 ohms and 1000 rms at 1 ohm? shit. class d is better tho. im taking out my passenger seat, battery is disconnected, going to unwire and take out the three amps, take out the 70+ lb box, then the platform so i can crimp 1 wire. Almost as bad as those fegs that put those horns in their grills and roll down the street distorting the block.... 1990 Jeep Cherokee 2 Dr. Big-3 in 0g on Stock Alt.

kingsuv Posted May 19, 2009 Report Posted May 19, 2009 Depends on the amps in question. Some (either class A/B or D) are more efficient then others in the same classes Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out. not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it.
jvillefinest Posted May 19, 2009 Report Posted May 19, 2009 A/B are usually cleaner amplifiers but are more ineffiecent D class is usually not as clean but ALOT more efficient. simply put 2007 Acura TSX Stock Navigation Rockford 360.2 (FOR SALE) Sundown SAZ3500 2 12" DC Sound Lab LvL4 @2ohm JL 600/4 2 Sets of Focal 165K2P
