Is doing the big three really worth it?

I did the big three in my other old school 70 skylark with a 150 amp alt. And i wasnt impressed. now i have another ride, a 69 oldsmobile toronado with a 100 amp alt and i am thinking should i do it.

Can somebody explain the pros and cons of not doing a big three.

I am running two amps off 0/1 guage cable to a distribuiton box spilt out to 4 guage.

One amp is a jbl audio 1200.bp. amp and the other is a lanzar 800 watt 4 channel vibe amp, old one not the new garbage.

In general, the answer would be YES.

If you have an anp that is rated at say, 80amp draw and another that is rated at 40 or so amps, you are already over the limit of the ALT. When you start to bump that 1200bp it is gonna yell back at ya.

Not only should you upgrade the ALT, you should upgrade all of the power and ground wires under the hood as well.

As an example, I am running an MTX 801D, it has a max draw of 75 amps. And I am running a Cadence 4 channel rated at 35 amps max draw. My stock ALT was 105amps. 75 + 35 = 110 amps + vehicle draw around 60 amps for all of the accessories plus the computer and well, it is obvious that the current ALT just won't handle it.

So, as of today I just finished installing an Iraggi 220 amp alt, upgraded the power wire going to the battery to 2g and upgraded all the ground wires to 2g as well. Guess what, My 801D actually performs much, much better at higher volumes and no more Dimming of the lights..

Also, not so much in your case, with computer controled cars, it is an utmost upgrade that must be paid serious attention to.

In your case, I would do it just to get all of the performance out of your system as you can.

Also, a note for anyone working with a computer controlled car, It is a must to upgrade the electrical system as computers offten tend to, or could blow due to power surges that could be caused by an overdraw from your amps. I was at one time a certified mechanic and still work on cars for people on the side and have seen or suspected this several times.
