If you are running two amps in your car would you need 2 compacitors for both amps or do they both connect?

you never need a capacitor, but yes you can use ONE with 2 amps. Just use it like a distribution block.

To tackle dimming the right way start by figuring out the theoretical current draw of your amps by dividing their rated rms power by 14v. That would represent your approximate peak current draw at full volume, divide that by 3 to figure a reasonable long term average.

If that number approaches or exceeds the current rating of your stock alternator then that may be the upgrade you need to make.

If it's close to or below the current of your stock alt you can help the charging system out by adding 4 gauge wires to the 3 main charging system wires -- batt to alt (+), batt to chassis (-), and engine block to chassis (-).

A cap is rarely a solution for dimming headlights. When they do solve that it's purely coincidence -- it is not what they were designed to do.

there are a number of factors to this question. before everything, the previous battery might have given up the ghost. A battery life of four to 5 years, incredibly no be counted if it quite is concern to a outstanding style of initiate/end operations, or use on a similar time as the generator isn't charging, is rather stable. Secondly, the traditional vehicle battery won't be designed to be concern to heavy loadings for long sessions of time. no longer understanding the intake of your amps i will in basic terms supply a simplified occasion - in case you have a battery with a potential of 60 ampere hours, theoretically it would be waiting to grant a million ampere for 60 hours, 5 amps for 12 hours, 10 amps for 6 hours, etc. This decreases using fact the battery gets older. So based on the potential of your previous battery, the amplifiers "might" have had a contributory outcome. Thirdly, in simple terms upgrading the battery to an stronger potential won't inevitably decrease the probabilities of the recent battery going flat or failing upfront. A "deep cycle" variety of battery could be a greater robust decision, those are designed for a much wider variety of cost/discharge expenditures. ultimately, is the generator as much as the job of offering the present mandatory to potential the amplifiers as nicely using fact the different electric systerms? possibly that should be upgraded as nicely! In a outstanding style of circumstances it in simple terms potential changing the regulator %. interior the generator or acquiring between a similar layout that already has an stronger charging cost.
