It sounds like you have either a dead battery or a bad connection in the power supply line from the battery. A blown fuse can cause the voltage to drop. This is fairly common with glass fuses in fully enclosed fuse holders. You need to use a multimeter to see where the voltage drops between the battery and the amp.

I have a 1000/1 amp running two W6s in my truck along with a 300/ going strictly to my highs, i also have a capacitor for 1000 that only runs for the 1000/ amp and a JL audio 100 amp fuse for all of it....


You need to get another capacitor and wire it in series with the fist cap when you crank the volume your system is not getting enough power from the alternator this is called surge current. In modern electrical systems we use capacitors to compensate for these surges.

POWER ISSUES


Recomend installing a capacitor, this will control voltage drop and reduce heat. The new battery should help, but it also may be that the amps final circuts could be wearing out, and no longer able to handle the load of the sub.

Will a JL audio 1000/1 amp run a orion HCCA 15


Hello evopower,

The JL 1000/1 will power the Orion HCCA OK.

It is stable only to 1.5 ohms so your best choice would be the 15.4 with dual 4ohm voice coils. In parallel, this would offer a 2ohm impedance. The 15.2 could only be wired for either a 1ohm load (too low) or a 4ohm load (less power).

Hope this helps.

Battery


First off, are you trying to stop lights from dimming? Because a capacitor is only a band aid to solving that issue. If you are using a capacitor for its intended purpose (to smooth out the voltage input to the amp, thus providing a more consistent voltage level), the general rule is 1 farad per 1000 watts rms. I hate to tell you caps aren't worth it, but this amp is a good amp. There are built in capacitors already. If you really want to see an improvement in your system, you will want a quality cap along side a quality amp. Look for an Alumapro capacitor. They go all the way up to 50 farads. High in price, very high in quality. Perfect compliment to an amp such as yours.
