When does it dip?

It does it randomly could be driving or braking sometimes even sitting in park

If it is an electric over hydralic plow pump you are going to see tha amp gauge drop even if you have twin batteries

I'm guessing that's for the plow but I don't have one on when it does it, just added the plow info because there's a lot of wiring for it in my truck

How many amps do the id tags on the subwoofer and amplifier drawing?

The amp I can't check I bought it preused from sound fx tomorrow morning I'll get back with exact models for the sub and amp

Disconnect the blower resister and see if the peroblem persists.

I'll have to give that a try I don't remember if it did it before that or not, I started driving in Feb last year and was gone the whole summer so basically had my blower on since I got back from bct. I'll let you know how it goes tomorrow thank you

Sounds like time to upgrade your wiring with the "Big 3". The wiring was not the best on these when they were new, and you are only adding to the load in ways the factory didn't intend.
Maybe add a capacitor to your amp.

What would you recommend that's cheap but good under $50 if possible

A 1 farad capacitor is good for a thousand watts. A .5 one for 500w, you see the pattern. Pick one up off Amazon for $50 I'm sure.
When I went to car stereo school back in 96, we asked about caps and which were best. The answer was there were only 2 companies in the world that produced them(at the time, may have changed) and you pay for branding and shiny stickers, didn't even have volt meters on them back then.
BUT.....if you have a system that requires a capacitor, you really need to upgrade your basic wiring first...aka the big 3. Look it up if you haven't already.
You already have a issue with your fan, fix that first.
Do some basic diagnostics first.
What's your voltage at idle, revved up, pull the fuse for the HVAC and test it again.

My truck does it too!! The only connection I’ve yet to mess with is the input to the fuse box in the engine bay. It’s on my list, all other main wires have been upgraded.

Pretty simple , your stuff wants more juice than your truck makes. Ohms law.

Amp you know the thing for a speaker? subwoofer and obviously if I'm having an electrical problem it would be amperage

Are you not having electrical problems? So using an ambiguous term like "amp" instead of "amplifier" or "ampere" would make little sense.
