siucsaluki11 Posted March 10, 2012 Author Report Share Posted March 10, 2012 unless i came across the wrong amp, that kenwood has 60 amps of fusing. so thats about 600w, 2ohm puts you well under that since its a 1ohm amp. so in reality, it cant physically do 700w at 2ohm or anywhere near that. "As for actual performance, most customers and tests say the same thing, that for the price, this is a great Kenwood amp, like most are. The problem is, however, one customer was quoted as stating that the amp is priced in the same range of comparable amps in the 600-700 wrms range, and it is not a true 900 watt amp. He also said "This amp has been tested at 644wrms @ 14.4v into 2ohm" and "if you are looking for 600-700wrms, this will be fine. But only produces around 72% of rated power (900Watts), as per Car Audio Magazine test," http://voices.yahoo.com/the-perfect-kenwood-kac-9104d-not-so-5408199.html Quote woman..cant live with em...cant shoot em...guess were all fucked You might be a Redneck if you use your leftover gutters for a speaker box port...

skittlesRgood Posted March 10, 2012 Report Share Posted March 10, 2012 im not talking shit about your amp and i understand people are sensitive when they hear their amp isnt doing what they think. im just telling you the truth and making sure you are set up for the extra power so you dont break something else. yes, im actually helping. now its not called "watts law" its ohm's law. resistance definitely plays a part and so does efficiency. something your math didnt account for. 14.4 x 60 = 864 864 x .75 (efficiency) = 648 (hey look at that, i was pretty darn close) then account for your voltage drop and im probably rite on the money. lastly, doubling the resistance should cut the power in half. this does seem to varry based on the amp's design but lets say, best case,(and your amp wont be this good) it drops %30 leaving you with 453w at perfect voltage. then we factor in impedance rise and holy fuck lol. you dont even want to know what that brings you to. now there is good news here. if you were happy with the output of this kenwood amp, you dont need to look for a 1000w replacement. just get an amp that truely puts out 500w at 2ohm and you will be set. that will really help you save money and get a better quality amp.

skittlesRgood Posted March 10, 2012 Report Share Posted March 10, 2012 ah, i see its really a 2ohm amp they just put a 1ohm rating on there just because. so the part about doubling resistance is not valid here.

Im probably going to just baby this thing till it finally shits then buy the AQ1200, which i should have bought back when i was working, not in school... Ohms law is voltage resistance current. (usually think of V=IR) Watts law is power current voltage(resistance if you use a different formula). (usually think of P=VI) You're not coming off in a very helpful way, its coming off as knock on kenwood, i said in the first post it doesn't do rated. I have my MECP basic. Ive worked for shops doing installs, I've done multiple installs. But that was all a while ago. I came on here looking for advice for a replacement. YOU HAVENT GIVEN ME ONE OPTION, so no, you are not helping. If you want to know about my electrical, FVCKING ASK. 1/0 Knukonceptz from front to back, and for the ground, stock alt, stock batt. Now that I've officially came off as a prick today, would you like to help or not, if so, list some amps, if not, piss off.

I've had it for a few years, i think i know the amp pretty well by now.

siucsaluki11 Posted March 10, 2012 Author Report Share Posted March 10, 2012 Also, im hungover, and a bit of a prick when hungover, and extremely pissed off when shit breaks, since my TV just died a week ago and i had to replace that.

01ExSport Posted March 11, 2012 Report Share Posted March 11, 2012 Actually had the same amp like 3 or 4 years ago. It always would hit alot quieter after heavy bass notes and then go back to playing normally. Apparently it's not all too uncommon. Quote Link to comment Share on other sites More sharing options...
