Nitro Amp

The new nitro amp I got today can produce 350 watts bridged for one channel.

Is that to much for my polk momo 10 inch sub going over the rms by 50 or will it be good to go.

It is all in the tuning! I have a 1000 watt RMS amp going to a sub that can only handle 600 watts RMS. I tuned it with a dmm and a resistive load to give me 600 watts RMS @ 75% volume with a 50Hz test tone. My subwoofer is still alive and kicking //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

350 to a quality 300w sub isn't a concern at all UNLESS...

You run at or near full volume a lot with a lot of bass heavy music,

OR you set the gain agressively.

good sub, it will handle that amp fine imo. that amp would be lucky to give you 300w. fused at 25 amps.

Good catch.... 25 amps on class A/B won't be much. I could have sworn the specs said 40 amps for the OP's particular amp.

I do have a Linear Power amp that has a 25 amp fuse that produces between 600 and 700 watts RMS before clipping @ 8 ohms mono. Before you call BS, I need to let you know that it has the TIPS high voltage mod

check the smaller pics under the big one. your moded lp is not even usefull comparison lol. nice amp you got though.

I am still no fallowing some of the stuff you are talking about

 

[gunz4me 10+ year member]

A general indicator of how many watts a given power amplifier will put out is its fuse rating multiplied times 10. Since the amp you purchased only has a 25 amp fuse, multiply that by 10, and you have 250 watts.

Keep in mind, that is just a general indicator.... Some amplifiers will produce more power with 25 amps of fusing, like my Linear Power and others will produce less.

I see thanks gunz for clearing that up I think it will work out well with the sub

Best explanation I have ever heard . Thank you so much for that . Nothing wrong with dumbing it down for people sometimes

And it's not really accurate.

Take a fairly efficient class "AB" amplifier(say 60%) that has dual 25-watt fuses.

Since we're talking about converting voltage into wattage out, let's do that first.

Assuming the constant is 14.4v, 50 times 14.4 is roughly 720 watts times the efficiency rating of 60% and you're looking at around 432 watts total output.

Take a fairly efficient class "D" amplifier (say 80%) with the same dual 25-watt fuses.

Again, assuming the constant voltage is 14.4v, 50 x 14.4 is roughly 720 watts, times 80%, and you're looking at around 576 watts total output.

If that "AB" amp was around 50% efficent, you'd be looking at 360 watts.

If that class "D" amp was around 85 % efficent, you'd be looking at 612 watts of output.

That is a 250-watt differential, and that is significant.

Just go by the RMS ratings unless they don't list them, which, if I were considering the product, I'd pass, as that's an immediate red flag when purchasing an amplifier.
