Hi to all,
Okay.. Today I put in new engine mounts the car ran great before so once i finished i took the car out for a spin it started and ran well then once the oil warmed up i tried to rev the car out and it started spuddering around 5500ish the car will spudder sometimes but it will also run out correctly half the time it will always revup with the clutch in? LMK if you have any suggestions.
No vaccuum leaks relays are good i did some research and there is no play in the vibration dampener.

I've got interference in my speakers, a high pitch noise matching my cars rev's, I'm sure you know what Iâ??m talking about.
I remember from a long time ago, reading that its something to do with the cables being to close to one another, the problem I have is that my battery is in the trunk so I've got little room to move them.
is there anything else I can do?
Car Audio : Determine Your Ampere's Pull

Hi to all,
This is all Information I myself have gathered from the MECP Installers Guide book.
Alright Here's the Question!
I am trying to figure out how much pull on my alternator I am getting from the amp.
Here is the formula We use to figure this out
I = (Po - n*Po + Po) / V
Now
I = amperes
Po=RMS
n=efficiency
V=voltage
So for me its:
I = (3000 - .8*3000 + 3000) / 13.8
So I do this
3000*.8 and i get 2400
3000-2400=600
600+3000
3600/13.8
260.87 This is my amperage draw correct?
and if I'm correct for everyone else heres an easier equation for this:
I = (2-n)Po/V
So for me this would go
1. 2-.8 =1.2
2. 1.2*3000=3600
3. 3600/13.8
And there we go. 260.87!!!!!
Now, We must remember that Most Class D Amplifiers have a 80% Efficiency Rating and Most Class A/B Amplifiers have a 60-70% efficiency Rating!
