HO ALT not an option, what else can I do?

add an extra alt

mail your alternator out to excessive amperage and let them build it up

The only problem I see is your still using a cap to band aid a weak electrical, I would go with two batteries both agm deep cycle's since your alt has decent output to charge them, just try to keep your amperage draw lower then your alt output and you will be fine so try to keep your amps wired to higher ohm loads and avoid test tones at full tilt for long periods and it should be very solid with minimal voltage drops.

I'm thinking that the caps would be great IF the alt put out more then you could consume but caps discharge quickly and take a second to charge back up I would go with the batteries first(the right kind of coarse)what I didn't like about the caps, if you read even how he described the use of them (If the engine doesn't start on the first try, in a minute or so the battery will recharge the ultracaps for another strong shot.) so even here he' saying even as large as they are they will dump ALL there power quickly now your voltage is even lower because your batteries are working to keep the amps/car going as it's also trying to recharge the caps that have dumped all there power already.

You can either

A. Get another vehicle that has aftermark support

B. Get a custom bracket made

C. Find somewhere to add another alternator

But you're setting yourself up for failure if you try to run 4k watts on that stock alternator. You'll end up damaging your cars electrical and your audio equipment.

He's clearly not in the untied states brah's.

Yes he's in India

There really isn't much he can do about it. If he truly wants to run 4k watts, then he will find a way to put a bigger alternator on his car lol, there really isn't a way around it.

I'd say your best bet is to:

1. Get a different vehicle

2. Run less power....

or 3. Contact (not Mechman or DC), Excessive Amperage, Ohio Generators, Singer.

I've head great things from EA, Ohio, and Singer.

Why I don't recommend Mechman: Bad business practices, I've seen too many things handled poorly. Fwiw, their alts have always had good reviews, when they do work and fit.

Why I don't recommend DC: Really really really slow build time for a lot of customers. I've seen so many people saying they took several months to get their alternator from them. I've also seen people saying it only took a couple weeks. Again, always heard great things about their alternators when they finally do get them.

Oh, and I'd recommend a ~300a alt if you're just running music daily. Even if you're running it full blast for comps, you're gonna need a battery/capacitor bank anyways. It's just a guesstimation, but I think 300a could be sufficient for moderate use with music.

If all else fails, maybe look into a GM 1 wire conversion.

Make sure you have a deep cycle AGM up front and add at least 1 deep cycle AGM battery to the rear. The deep cycle allows for a deeper constant discharge and the ability to be drawn down and brought back to full charge without damage to the internal plates. The Absorbed Glass Mat or AGM type of deep cycle batteries discharge and recharge quicker than a regular flooded type deep cycle. This effect can be enhanced further by using the same type of batteries throughout the system. You do not want to mix normal starting type batts with deep cycle, or worse flooded cell with AGM, they charge differently and will have adverse effects on the whole system and possibly some premature batt failures.

A dash mounted voltage meter will keep tabs on things and you know what is going on at all times.
