Alright so i got a boss blx3500M sub amp. I have read all the forums about these amps and have heard nothing but bad things about them. This one says 3500 peak, 2000 RMS at 1 ohm. I am going to wire it down to half an ohm also. I am going to run 2 2006 kicker 12" L5's in a sealed box. Will this amp be alright to power these? the subs take 600 RMS so even though boss overrates their stuff, it should still power it. This will be alright though right?

why do you want to blow your amp??? maybe im just confused, but if it says 1 ohm stable, and you have read nothing but bad things about them...why woud you wire it to half ohm.

Hope you have more money to buy a bigger amp the first few days you attempt to run it like this

I can see NOTHING but bad choices here: Boss amp. Wired to 1/2 ohm (on purpose). L5's. (wait... never mind the L5 thing, you obviously dont care about SQ... the Boss amp is evidence of that)

This will do nothing but cost you... soon!

Ok while this probably was a bit stupid, that's a harsh response guys. Ok, I am just jealous you guys beat me to it. But well... Doing theoretical math... 2000 RMS doubled(1/2 the impedance) would be 4000 RMS correct? Well ok even a severely overrated amp isn't gonna be like 3000 off on rms... The subs can only handle 1200 total... Not a good idea. Ontop of already running the amp at a lower impedance than it is stable at... I mean, be smart about it man.

ok csprings had his info wrong the amp he is talking about is the boss blx3500m this is stable down to .5 ohms and irts fancooled and it is 2000 watts RMS at .5 ohms. Now my question that maybe someone can answer is how many LEGIT watts will the amp put down about at .5 ohms since boss overrates their stuff???? in RMS, and can u please use facts to support your numbers. thanks in advance

sorry bout the double post but ALSO   heres a link to the ampv   https://www.cardomain.com/item/BOSBLX3500M

again, the amp will not handle a 1/2 ohm load.   if you look at it on the site you posted, or at boss audio.com   it does not list a 1/2 ohm power   DO NOT RUN IT THERE

it has 3 40 amp fuses

here is the math

120amps of current draw before blowing the fuses

13.8 volts constant. You voltage does not move at all, this will never happen but will use it for the math

amp efficency at best 65%   most amps like Kicker and crossfire and other respectable high end amps do not get better then 75% efficency

so here is the math

120 x 13.8 x .65 = 1076.4 watts at 1 ohm with perfect voltage

so yes, the 3500 watt amp is rated over by 300%+



The amps I use personally are externally fused as reccomended by the manufacturer at 300 amps each

we run our new setup on 17.7 volts for show use only

the amps have an efficeny rating of of 65% at 1/4 ohm

our setup comes out like this

600amps x 17.7 volts x 65% = 9779.25

Our voltage does not more due to a kinetik bank of 4 cells, and 2 very very large alternators!

yes it does read the description it sayds that the amp is stable down to a half an ohm load. i quote "Exxtreme power is what you get from these high current, low impedance amps. You can even load them down to half an ohm for maximum power output! These high current Blade Exxtreme series amps are equipped with internal fans to dissipate heat....." so i figured i could wire them down to half an ohm. So when u use that formula, that calcualte Peak Power or RMS power?

If the same site or spec sheet told you that when you use this amp you can see in the dark, cure cancer, breathe underwater and save the whales, would you still believe it then?

ok but they cant just lie and car domain wouldnt lie, but if the amp sarts to get too warm ill just change the load on it. OK..........

Now this was the main question about how many LEGIT RMS watts can the amp put out if they say it outs out 2000 @ .5 ohms about? I dont need peak numbers just RMS.

so his answer is in RMS????

In a perfect world yes. This the most it can possibly produce continously at 13.8 volts being fed to it, @ 1 ohm.

The did lie, they do lie and other people believe it and pass on the lies, as you are beleiving them right now. Since birth, you are trained to beleive what you read. You unfortunately do not believe what the people who know better are telling you and are bent on not listening to us. The results have been posted for you to see, yet you are looking for someone to say different. This is not going to happen from any one of the senior or even junior members of the forum that know better.

12000 watts @ .0625 ohms with 18.5v input, 648.64864864864865A, with ABSOLUTE fidelity and efficiency! It IS after all, Boss! Go for it!

Kidding. Now read here: Clicky!

That amp WILL NOT MAKE THE POWER ADVERTISED! It can't do it! Those are inflated numbers. All they do is burp one channel at 1kHz, for 1/10 of one second, figure HOW much power that one channel made for that period of time, and then extrapolate the numbers out to one half ohm, than double it (for stereo) to make it seem more powerful than it CAN EVER BE! You cannot get more out of an amplifier than you put into it. This question has been answered over and over for you. If you are worried about RMS power, then BUY an amp with believable, respectable numbers, and follow the advice posted in my link above.

The most your going to get out of that amp is 1000 watts peak struck by lightning, and its going to make the bass notes your recording artists spent soooo many hours perfecting sound like a wet fart in the bath tub.    Take the amp, place it in a box, and ship it to me so i can video tape it blowing up, they all should be destroyed, they are cancer in the car audio world.

Thats how much a REAL 1000 wRMS amp costs, now tell me, do you really think boss can possibly find a way to produce 4000WRMS at $300? nopers
