Resistance Problems

[mtlhead 10+ year member]

I appreciate the actual help you are providing //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.
I already have backed the gain down a notch.

Here's my plans:

Run 2-3 more cheap batteries inside the trunk (I'm broke, leave it alone please).

Run my 8ga kit to said batteries with a 40a fuse as a charging wire. Run 8ga from those batteries to my amplifier.

Wouldn't that help solve my issue?

My other thought was to run a 2ohm resistor and wire it in series with the sub in the meantime. I don't know if that'll work though.

skip the batteries

do the big 3, run a bigger power cable to your amp

OP I was running almost 1k rms on a battery that sat at less than 11 volts with the car off, and wouldn't hold a charge above that, and a 60 amp alt...Unless ur amp is as efficient as rectangular wheels, you shouldn't be having issues pulling 600 watts especially on music, you probably have a bad connection somehwere or are running 220 gauge power wire to your amp or something

The problem isn't my alternator (to the best of my knowledge). I belive its my cheap battery up front. Its a Bi-Mart special for $25....300cca on it. My car is supposed to REQUIRE 400-500 or something like that. So I think I just need a few more of those cheap batteries.

dont get more cheap batteries man

get one good battery up front

big 3

bigger power cable

That isnt that much power...you should be fine with replacing your battery with a higher-performance one and also upgrading all of your wiring (Big-3 etc.) as well..

And the resistor idea=no...keep in mind the resistor is *technically going to get half of everything being put out by your amp and will need a pretty high power rating to sustain it (it'd have to be a large resistor)...and also, by having it take half the power, you arent much better off than running it at 8 ohms...or just back the gains down and turn off the bass boost

You keep saying big 3. What is that?

So what can I do for a GOOD battery that is inexpensive? When I say I'm broke, lol, I don't think you understand. I work 2-3 days a week min. wage to support 2 people. I'm BROKE. I'm just trying my hardest to piece this thing back together to work properly.

So get a good battery up front. PROBLEM: I've got a 91 Buick Regal. That means a small side post battery is needed. Can I get a good battery that fits that description?

And I'll get bigger power wire last. That's the last thing on my mind.

big 3 is upgrading your stock electrical by ADDING power/grounds

alt to battery positive

battery negative to chassis

chassis to block

Gain is almost ALL THE WAY DOWN at this point, and bass boost is 100% off. Crossover is set to 60Hz. I understand that the resistor idea would mean it'd get half. So running at 8ohms would be better than having a resistor pulling on it? When I had two subs (2ohms per sub, 4ohms at the amp), they got plenty of power (not enough.....but enough for my ears).

why do you have the x over @ 60hz

Its set to 60Hz because the higher frequencies are what is making the amp go into safe mode. And even there, its still cutting off sometimes.

Turn down the gain.

is there a switch on your amp that says HPF or HF, LPF or LF, or anything like that?

Nope...monoblock amp. All I have is a frequency knob.

What im saying is if you put that resistor inline like that youre pretty much putting a 2 ohm sub inline with it (a sub is just a resistor in a circuit...but converts the energy into mechanical AND heat...where as the resistor is just converting it into heat/thermal energy)...

Just like if you have two SVC 2 ohm subs in series...and your amp is rated at 800 rms @ 4 ohms...that means each of your subs will get roughly 400 rms a piece (and if it wasnt that way, that means youre creating energy...which no one besides me //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif knows how to do)..

Yes, I know that's exactly what it does //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif. I have a little background in electrical. I'm just trying my best to find the RIGHT way to fix this...but inexpensively.

And about 3 days ago I HAD two of these subwoofers running at 2ohms apiece, 4ohms at the amp. Which is the reason why I was thinking a resistor. I already know what the power is like when there's two of them. And this box is 10x better than the sealed crap boxes I had before.

what impedance are your subs?
