Have 2 JL audio mono block 500/1 amps hooked up to 2 JL12v2W6's an a 1.6 farad lanzar cap with 0ga running from the battery to the cap an to the distrubution block then 4 ga to my amps. then the grounds from the amps and i the cap to a smaller distrabution block an to the body of the car.. it powers up 4 about a min then both amps shut down but i test them an they have power but dont run the amps. then i take the fuses out then put them back in an they turn back on. then shut off whats the deal should i ground them all seprately?

Current actually runs from neg to pos. If you need 0Ga for these amplifiers ( not sure of their current draw) the U NEED to have it on both the Pos and Neg. Neg should be as short as possible to the body, remove paint and use "coppercoat" grease and bolt/nut to the frame. Then add a 0 Ga wire at the Batt from Neg post to the frame/body.
Use the proper size fuse from Pos of Batt with 0 Ga back to the amplifiers. use power dist block 0Ga to 4Ga to each amplifier. Most amplifiers in MONO (1 CH mode) can handle 4 ohms but check your impedance configuration.
-Did you verify that you have an input signal?
-Is the amp going into protection?
-If they are bridged mono, are they bridged across the appropriate terminals?
-If there is a subwoofer line out on your head unit is it muted or turned off?
The answer is yes, any amount of amplifiers can be hooked up to a cap. Obviously the more amps you hook up to it the less you are going to nodice the difference with the same amout of farads. The only thing that I am worried about is the wiring from your battery to your cap. As long as you have a decent gauge wire running back you should have no problem. And for this instance I would recommend 0 guage, you might be able to get away with 4 but I would highly recommend 0. Over all I would recommend 0 guage on all installs unless you are going small and don't plan on upgrading. I hope I could help
Both "+" connections on the cap are tied together within the cap, as are both "-" connections. Lanzar provides two sets to allow the cap to be more easily shared between the power/ground lines of two amplifiers. If you have only one amp, connecting to one or both of the +/- sets should not matter (although connecting to both +/- sets might reduce the resistance between the cap and the power wiring of your amp).
somehow, DC car voltage has gotten to the speaker outputs of your amp! your fuses are saving your speakers from meltdown. your amp has melted down. toss it after checking with ohmeter as follows:
disconnect amp completely. red wire from ohmmeter to +12Vin. black wire to SPK+. if ohms are anything below 1000 ohms, then toss it. An electrical short is equivalent to flooding your entire house with a leaky faucet. No telling what that rapid current will encounter along the amplifier section. you could get lucky and find all power MOSFETS have shorted and replace them. good luck.
