Mind you I am doing this with a stock altenator!  I do not have $600 for a HO alt.

I was told , I can get by with a bigger power supply. My   SPL  setup is (1) earthquake PHD2  aprox. 1000 rms/  (2) Kicker solobaric  12''s . This setup is in my  02' camry.

(1)kinetik khc2400

(1) yellowtop 31 series (Front)   /  (1) Kinetik khc1400 (Back)

(1) Blue top  (front) /  (1)kinetik 2000 (BacK)

As soon as you breathe the term "SPL", get busy looking for a HO alternator.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I agree with stevdart. Check out alternatorparts.com for some decent prices and kick ass quality. As far as the batteries go keep matching ones otherwise you will lokking at isolating blocks additional wiring and more money

Agreed with all above.

A "bigger power supply" or battery will never hurt. However, any correct battery for your vehicle that is in good condition will do it's job...which is starting the vehicle and to help with filtering ripple current which comes from the rectification (converting of AC to DC) after the alternator or internally depending.

Now realize once you begin to tax the charging system by coming close to or exceeding it's rated output this is when you will suffer loss of output and eventually hurt the alternator and possibly other components of the charging system.

Just think about it logically. Now the stock system has to be able to do it's normal job keeping up with the stock demands..PLUS all the extra demand the audio system added to it. Compound this problem by adding another battery (now it has to charge that too) and you can see how this will become an issue.

Make sure you take care of "the big 3" and if the demands of the charging system is exceeded by the sum of the stock current demands,additional battery and the audio system you will need to upgrade that alternator as well, especially for SPL use. You did not mention the vehicle but you might be able to find a suitible HO alternator for well under 600 dollars that will suit your needs, of course this depends. Shop around.

As well if you add a second battery read up on how to do it properly...just running cables from one battery to the other is NOT the right way. They must be isolated and there is more then 1 way to do this, again depends on the application and needs.

Good Luck.

It takes power to make power.  Your SPL is limited by the weakest link.  You could spend big bucks on the amps and subs but if the alternator can't make enough current, the amps can't make the power.

Whoever told you battery instead of better alternator told you wrong, it doesn't solve the problem. Save your money for the alternator, it'll pay off much more in your system.

Besides, I would think you can find a cheaper HO alt for a Camry than $600...? Anyone?
