A second battery will only let you run your system longer with the car off, or let you drain the second battery with the car off and your system playing instead of draining your main battery (so you can start your car).

IN GENERAL, Caps are a waste of money for most people.  So are extra batteries.  If you want to power a large system, a high-output alternator is the only solution that works.

I dont understand all of this CAP bashing. A cap is for holding onto large amounts of power to be used when the system needs to peak (eg, a large bass hit). Without this, when the amp needs the extra power, it has to get it directly from the battery. A battery is a device that is made for longterm slow power output, not really up to the task of delivering large amounts of power on demand. A cap on the other hand is short term power  holding for very fast dissapation. Which is kinda what you want when the amp says "gimme some power, i gotta make some bass". I dont know what you guys have been running in your systems, but i run atleast 2 one f caps on a 600 watt rms amp Every time. and it make a HELLA difference in bass responce and distortion reduction.

thats my take.

They arent saying caps dont work, but they are band aids for electrical systems with not enough power...How much is a 1 farad cap retail these days..like $150 - $200 beans?  You can add a couple more dollars to that and get a high output alternator and solve all your problems..

Yes, a high output alternator would help out allot by putting more power into the circuit, but does it solve the problem of quick high power consumption by the amps? This is one thing that sets most amps apart from others is their amount of power capacity built in. Isnít it obvious that by adding an external cap, their would be no more problem with power deficiencies?

Caps can help out a system greatly, but in my opinion the correct approach would be to get an alternator, and then a cap....if needed....but you are right about them helping when there are quick high power draws ...but they dont necessarily "solve power deficiencies".

Good point. I agree.

Where can one find a Hi output alternator and what defines a Hi output alternator?

You can search on Ebay, thats where i bought mine. Sometimes you call around to local shops that deal with alternators and you can get them to "deuce" yours up... (add more copper coil) which increases the output. Only bad thing about this route is normally the shop won't warrantee the work. Personally i define Hi Output as 200amps and above...

actually a cap will help you to lose 1-1.5 db ... if you want an honest answer... what are you running.. ? and in what car .. where are the amps.? what size cabling? notice you dont see caps in db cars. ?"spend 150$ on a cap or 150 on a batt.?  let me hear what you got..
dont be a pet monkey ..use your dmm
