amp clipping

[shammyhavik]

i don't want to smell the voicecoils on my SQ 312's for a second.

with a 1400 rms re ztx 3000. 1 all i have to worry about is clipping the amp, not overpowering the drivers.

should i set the gain as 1000 rms with my DMM to be safe?

also with a sq 2200d what will voltage drop cause? will that damage my woofers too?

Can you rephrase that into decipherable questions in English please.

I'm going to use a "1400" rms amp for two SQ 312's until i recieve my SQ 2200D amp.

I realize amps that aren't efficient kill drivers. so should i underpower my 312's to be safe until i get my monster true rms amp?

second i am wondering what exactly voltage drop causes and if it will hurt the drivers or amp.

Amps that are not efficient kill drivers?

That is incorrect.

Only 2 things kill a driver-

Mechanical or thermal failure.

Should you underpower your subs?

Do you always listen to everyone's stereo at full blast?

Have you ever noticed turning DOWN the volume doesn't "kill drivers"?

That's a pure example of "underpowering" that will never cause failure.

Voltage drop causes the following-

DC voltage will obviously be less.

The available headroom the amplifier has will lower with less voltage resulting in output able to clip sooner if volume level is retained under lower DC voltage.

Because of this, the voltage rail will be unable to output at the same designated AC output and will drop both voltage and current. Same result as turning it down, but without losing it's headroom.

Efficiency also drops but no where near as much as wiring lower and lower.

If regulated power supply is used, amperage draw will shoot up to maintain power output. Your amplifier is not regulated.

If low voltage is always maintained, the cycle life of the battery(ies) being used will also shorten and will take longer to charge if only using an alternator.

Continued use in this scenario can result in alternator failure if your alternator is not equipped with onboard protection.

Intentionally driving battery(ies) in this state is best used using LiFePO4 technology.

Good news thanks for the info. I still am trying to understand voltage too well ha.

That's what YouTube is for tho

Thanks again brodie

We could go on for months about electronics.

Go here- Basic Car Audio Electronics and maybe even Car Alarm, Car Stereo, Mobile Video, and Cruise Control Info for Installers (read their articles and diagrams) and you should have a ton more knowledge.

Are you already smelling the coils or are you just overthinking sh*t?

 

[bernouski]

lol i am over thinking my *** off man. thinking about big 3 electrical thinking about upgrading my power wire, my alternator, a voltage meter, getting a SMD distortion detector, getting new distribution blocks or a cap/distribution block bahahaha.

Where i am at now, I don't have the HDS312's YET. They are in the back of a truck on the way here.

But with my current set, two JBL GTO1214D's I am smelling the coils all day when i bump to 1000+ RMS. Pulling the full 1400 RMS out of the amp and drivers themselves is out of this world cuz the smell is over powering.

Like i said though "I don't want to smell the coils on the 312's for a SECOND!!!"

that's just because i want to have these drivers for a good while since I know they're the best i'm going to get for a good amount of time.

also my current amp is RE ZTX 3000.1D if ur wondering

 

[bernouski]

oh yeah voltage meter, that reminds me, can i wire my voltage reader to my fuse box exclusively? I ask because I have this nifty little compartment which opens and that is directly next to the fusebox which i see as perfect for being discreet and stuff

 

[shizzzon 10+ year member]

What's more important to you?

Monitoring your amp or your fuse box?

 

[bernouski]

the amp is more important. unless they all are intertwined mechanically and read off the safe

 

[shizzzon 10+ year member]

then voltmeter is ran to the amp.

SMD detector is not going to prevent transducer failure. It's a passive device.

Might as well just use a DMM which is terrible idea too.

 

[bernouski]

first i've heard of a transducer failure, whats that?

i use a DMM for pinpointed RMS and the SQ 2200 comes with a distortion detector i think

 

[shizzzon 10+ year member]

Transducer= speaker

You can't use a DMM to "pinpoint RMS" as i said is terrible idea.

RMS = i'm assuming you mean wattage.

You cannot even get VA without an amperage reading.

All a DMM will tell you is what the rail is putting out.. not what the impedance or VA is.

You cannot get wattage without phase angle.

And yes, you can be a large multitude off by just measuring voltage.

However, measuring voltage ALONE can at least tell you whereabouts the limits of the rail is.. BUT ONLY if you knew the impedance being measured(again, you need an ammeter).

Now, luckily, if the amplifier comes with a clipping light, at least that's an active device.

No clipping light on this planet is accurate for when measuring music as it's not designed to measure dynamic material.

But, this indicator can give you a "general" idea of where to and not to be at.

It's a lot better than any other method mentioned previously.
