Need help choosing a powerful good amp for competing

[Abel 10+ year member]

what super powerful amp is going to be fuse efficient

Ihad the MTX on 50 amps of fuse and it put out just under 1400 watts id say thats pretty efficient

im going to be runing the amp @1ohm how much power does it do @ 1ohm and whats the price on that ia amp //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

it says 1800@1 ohm, but if you can go lower, it can go lower. Email nick about pricing, his contact info is on the site.

There might be 1 or 2 left F/S on here.

ia are 699.00 for the 20.1s and the new 40.1 will be 1399.00.

They only make thier power and are worth the money if/when you drop them low and they really shine.

Know anywhere to get a killer deal on a Zx2500.1???

Cheapest I can find a New Kx2500.1 for is 800.00-850.00 and there arent many new left.

Also the thing everyone says they are droppin to 1ohm or .5 ohms or such and getting a amp for this,and are forgetting about rise.

Are you talking about 1ohm at the sub?Cause it will be way higher after rise and a 20.1 aint gonna cut it then now way no how.

This may be a stupid question , O'well. If you have 4 ohm DVC. How can you run them at 1 ohm ? I have the same subs 06' 2-12 L7 DVC 4ohm, I thought they could only be wired to run at 2 ohm. If I'm wrong please tell me. I thought they had to be DVC 2 ohm to drop to 1 ohm.

One can go down to 2ohms. The the 2 of them can go down to 1ohm together,

4ohm sub to 2ohms bridged(one sub) to 1 ohm bridged to amp(both subs at 2ohms).

70amps?12volts?

840watts?

14volts?

980watts?

16volts?

1120watts?

sure, maybe it can be run with 70amps worth of fuses, if you only want about 800watts from it, off 12volts... //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif

From bcae1.com:

Fuse Opening Time:

A fuse does not blow when the current reaches its rated current. It is designed to pass its rated current without opening. A fuse will take varying times to blow under different conditions. A fuse will pass significantly more than its rated current for a very short time. It may take 10 minutes or more to blow a fuse at 25% over its rated current. The table below is an example of the specifications for a slow blow fuse. You can see that a 20 amp fuse may pass 40 amps of current for as long as 5 minutes before blowing although it probably wouldn't take a full 5 minutes to blow. The times for other fuses will be slightly different.

%of amp rating Opening time

110% 4 hours minimum

135% 1 hour maximum

200% 5 minutes maximum

You also need to remember that the fuse is not seeing a straight DC current when playing music. . . .the on and off of pulses of high DC current further extends the max current through the fuse and the length of time it takes it to blow.

i'm sure experienced MECA competitors know which brand of fuses to buy too:naughty:

the 20.1 is a pretty efficient class D, imo.

I had a class AB amp, that had been measured to give 2 X 84watts by the manufacturer at 4 ohms per channel, and something like 115watts per channel into 2 ohms.

I ran it at 1 ohm per channel, and blew the 30amp fuse it had... I originally thought the amp was cooked.

this was only like a few minutes of music btw.

30amps, lets say, 13.4volts, fuse will apparently handle twice its rated power for 5 mins max, so, that would suggest I was pulling 800watts from the battery? which, well, for a class AB amp, would still suggest 400watts output power...

yea we do lol well mark and les and told me which to buy //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

i think i can get one for 700ish dunno checking for sure on monday im getting one on monday then testing it then maybe buying 1 in couple months //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif tho i lik those mtx's sounds loudd for only 1 mtx even mark was surprised //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
