im limited so wats the best choice

[joemon]

Ok I have a 91 Nissan 240sx.

I have a Kenwood amp (x1200m) for bass set @ 4ohms with 800watt/x2

Then a Kenwood amp (x600f) for high/mids set @ 4ohms with 400watt/x4

My car has a standard battery up front for starting and

A optima red top battery in rear for amps.

Both batterys hooked up with 0awg power with both grounded with 0awg to the car.

I have a 2far. Cap for bass amp.

Wen I turn up the music to almost max listening volume my car with start to have lights dim and my RPM will start to "lug down".

__--___-__-__-__-_-___-_-_____-__-_________-"----_-

Ok now the question...

For my car I can't find a HO alt for my motor(ka24de).

Why does my car still do the dim of the lights and the lug on the motor?

So...

Should I just do the big 3..

Or

Take the cap out..

Or

Add another battery (like the xs 1200d battery)..

_-But I'm going to buy another bass amp (x1200m) and run each amp at 2ohms with 1200watts for 1 subwoofer-_

Plz help

Imma try to post a video of my setup and problem in a day or so

Thanx every1

I would start with big three and removing capacitor. Then i would replace starting battery. After that i'd put another battery in the back or sell red top and upgrade.

And also I have looked online for this and I can't find the answers I'm looking for that suites my situation.

So ya with the red top should I use it for my front battery and get a xs 1200d battery (or anything equal to it) for rear and ditch the cap? Or get a bigger cap after changing the batterys with the big 3

Drop the cap all together, caps 99.9% of the time do more harm then good. Upgrade the battery and do the big 3.

Put the redtop in front and put the XS in the back.

I would ditch the cap and yeah if the red top will fit up front you can do that with the big three and then put an xs or kinetik battery in the back.

cheak around town and try to find a alt place they should be able to rebuild it i got my 100amp alt rebuild to 180amp for 140 bucks

[lem43606]

like the other guys said ditch the cap. put red top up front and get another nice battery for rear. Big three helps a ton as well

[joemon]

Ok that's wat I was thinking

But is there a HO alt at all that I don't know about for my nissan?

And about the rebuilt of the alt I just may need to do that research.

But wat do u guys think about thoughs hybrid caps that r 10+far

[Rebel4055]

Get off the cap deal. Caps are just a bandage for systems. Get a new alt,put the red top up front and put the XS in back, do the big 3. Your electrical will be very happy.

[joemon]

Ok just never had experience or knowledge of the big caps

But 1 more thing too.. would a 200amp isolater between the 2 batterys help at all?
