for my alternator?

i currently have a 200watt amp running my speakers, and a 200 watt amp pushing 2x8's in the doors of my 2007 mustang. I want to add a 200 watt amp to push 2x10's in the trunk, will it be too much?

(i already have the 10's in a box and amp and related wiring)

 

depends on which 200 what amps you are talking about as they are not all equal, but you should be ok.

 

i have a alpine mrp-f240 amp pushing my boston acoustics speakers
JL1 e2150 pushing my 8's

i would like to add a JL1 g1300 300 watt amp to push JL1 2x10's in the trunk

 

I have five amps, so "No".

The alternator is not the source of power in a vehicle, the battery is.

 

You're fine. I run a 1000w and a 475w just fine with no dimming, etc...

 

Incorrect kind sir, the battery is only the storage tank, the alternator is the energy supply. Let me make it easy to understand.

1. You have an Optima battery, but a undersized alternator....your audio system will perform poorly and you will have overheating issues.

2. You have a high amp alternator, but a undersized battery.....your audio system will never know the difference unless the engine isn't running.

The alternator is much more important for the performance of an audio system.

To the OP, your 200 amp alternator is more than enough

 

You're very young, and wouldn't know who I am, so I'll take it easy on you. You've defined a "Storage Tank" and an "Energy Supply", yet I'm talking about a "Source".

You can start your car with a battery, but no alternator. You cannot start your car with an alternator, but no battery. The battery is the source. The alternator just puts back what energy has been used.

This is also a very untrue statement, If your car isn't running, can you power anything with the alternator? You can certainly power everything with a battery...

...but I digress for now...

 

not many of us know that they are in the presence of audio royalty, and then there is just a bunch of us that don't care or know that we can be anyone we want to be online.

They are both important to get the best results, arguing that one is more important then the other is like arguing that water is more important then the powder in tang.

now all we need is some monkey to come in and recomend a cap..........

 

Power is voltage times amps; W=E*I, 12v*3A=36w
Also, I=W/E
1000w/12v=83.33A; doesn't matter whether it comes from the battery or the alternator.
600 watts of power requires 50 amps of D.C. current into the amplifiers if those amplifiers are 100% efficient.

 

Not necessarily. Music is extremely dynamic in nature and generally under normal listening circumstances, one is only using a fraction of their available RMS power. Granted, there are some exceptions to this, such as any genre of music that has test tones masquerading as musical content. That would be your rap, drum and bass, dubstep, and other forms of electronic music that is bass heavy or have long, lingering, shifting, bass lines throughout the track.

Also, at low volume levels, Class AB amplifiers tend to draw more current than Class D amplifiers rated for the same amount of RMS power. It is an inherent flaw in the class ab design where they generally are not efficient at lower volume levels.

To explain the point using Ohm's law, let's assume that 600 watt class ab amp is 68% efficient at maximum output. It would output 600 watts RMS while drawing roughly 74 amps of current to make that power (74 amps x 12 volts x 68% efficiency). At 100 watts RMS, that same amplifier may only be 20% efficient. As a result, it would draw approximately 42 amps of currrent to make that power (42 amps x 12 volts x 20% efficiency). Note, I arbitrarily picked 20% for the lower output level but I have seen efficiency as low as single digits and as high as 50% at lower volume output levels.

With all that said, I am running a sub amplifier (Clarion DPX1851) with 90 amps of fusing and a 4 channel amplifier (Lunar L450) with 70 amps of fusing. All I have is an Optima red top up front and whatever alternator the prior owner of my vehicle installed. I think the alternator is 160 amps, but don't hold me to that. Anyhow, I rarely encounter dimming issues at night unless I happen leave the volume rather loud level while stopped.

Now to answer the OP's question. It shouldn't be too much BUT I don't know your listening habits nor do I know which genre(s) of music you listen to. If you constantly keep your volume at 11 (Spinal Tap reference) while listening to electronic "music", you may find that your electrical can not keep up.

Disclaimer, I am tired, so my response may be a little spastic. I'll correct myself after my morning coffee.

PS: I've heard a lot about you AudioNutz, mostly good! (hahahahahaha)
