Thanks, I think it's only the one sub & I do think the sub is the problem.. [i set amp gains with a dmm. I doubt it's +/- phase (wired parallel...final ohm checked with dmm). I spent a month building/sealing the box (3 chambers, 1" MDF, triple baffled, several coats fiberglass...

I have 3 w12gti's & 1 of them, at higher volumes, will hit a bass note & make this popping sound. I listen to EDM & at a certain point, like after a buildup & the bass comes back in, the kick drums will become this distorted "bok" "bok" "bok" (call me for exact pronunciation)...

Ah ok, well called Mechman & they didn't think the sense idea would do anything because "everything's happening internally" (it's also not actually a self-exciting alt). There was a "Ford guy" at Mechman when I called, the guy on phone was talking with & it just seems to come down to my...

Just a little update. Clearing out my PCM memory did wonders for stabilizing the "constantly changing" voltage problem....now it's much more centralized around 14.1-14.4 while driving. My car drives & shifts smoother & my subs sound startlingly more punchy & "confident" (& they...

Is yours 3-wire? Because mine's 1-wire (self exciting). I don't think there is a sense wire.

They also mentioned re-flashing my PCM....but I have a base warranty on my car & didn't want to take my car to Ford with a non-approved alternator. But NOW I'm thinking.. Would just clearing the PCM's memory have the same effect?? Because THAT'S easy. Reflashing involves the software &amp...

Mechman said it's possible the vehicle idles below the turn on speed of the alternator, so I'll get a brief spike as rpms come into the turn on range.

Thanks, this isn't random though...it's when I first accelerate from a stop...then it's fine. Mechman's view is it's "common" with Ford PCM's.

I appreciate the idea....something in my gut doesn't sit right about possible drawbacks (safety concerns?). I'm not sure. If I ever sell the car I don't want it "rigged"...but I don't want it spiking either. I pictured upgrading my electrical improving the safety & health of my car. I'll...

Ok I don't know what the sense wire does. Is that basically bypassing the PCM & my alternator dash light would be on all the time?

Before I put in another alternator I'd need to be convinced it would solve the problem. The fact that the voltage spikes on take off (& Mechman saying it's common with PCM's) doesn't quite make sense to me. Are the regulators inside it not for regulating? If at idle, the alt turns off, then...

I'm really curious what the Singer alt specs would let me expect ....I'm about to run out of here & will be back. I posted what Michael Singer told me in OP. I'm sure his alts are great. Thanks I appreciate the comments

ah ok....I also mine being 2005-2007 is different than 2008 models

Mine is under the whole car....I've seen one video of a guy saying you can get to it from up top & lists all the things to remove out of the way....but it's more just saying "you can get it out".... if I start trying this, I might be stuck needing a tow. Popwarhomie what is your car? Is...

Can I ask what year escape? I didn't realize 3.0 would make a difference.....but I know whenever I call any shop asking for estimates...there's always the same tone they get once they look up my car like "yeah....that's not a small job". I had 2 appointments just to spend the $300 to have shops...
