amp not responding

[Reaper 10+ year member]

I just hooked up my 2100 watt brutus amp as soon as i put the rca cables to the input it starts to drain the capacitor.

Did you charge the cap?

yes the cap is charged

I forgot to mention the hifonics logo gets dim, but the power indicator is off as if there were no power running to the amp.

Put a multimeter on it and check the voltage

um, so you have no remote power? is there a stray wire touching the remote terminal from the positive wire? is there power feeding the cap, or the main fuse out?is the amp and cap grounded? the only things i can think of related to rcas is 1-(most likely) no ground, and it;s grounding through the rca shields, or 2- the amp has, and is set for auto audio turn on, but i don't think the amp has that feature...

right now its at 11.6, and the amp only stays on when the rca cables are on the output

yes i have remote power,no stray wire from positive to the remote terminal, there is power to the cap, no main fuses out, amp and cap are grounded. RCA only work on the output

Dont stick them in the out put.. Your voltage is way to low, is that with the car running? If so you have a problem, if not you still have a problem

No when the car is running its at 13.7 or higher sometimes, IF i put the rca cables in the input nothing happens there is no power , and the Capacitor starts to drain quick, But the hifonics logo remains on and looks dim

Horrible ground. The amp is actually getting a better ground through the rca's than to wherever you have it grounded. Unfortunately, once current begins to pass through to turn the amp on, the voltage drops too low. In short, you need a better ground. Don't plug the rca's in the amp output. Even if the amp came on, it couldn't play music this way.

do you think its the amp? When i touched the rca cables to the out side of the input( out side of the female ends) i got the amp to work for 2 seconds and then it went out.

thanks! I will look into that. what do you recommend I do to better ground this.

Picture of current ground would help. I also think you need to get your battery checked. It should rest around 12.8

Battery is New and it does rest at 12.8

For an ideal ground you want to find a piece of sturdy metal, the chassis is ideal but if you can't use that a bolt for a seat usually works well. You don't want something flimsy, minimal resistance is the key. Get a grinder or a piece of some coarse sandpaper and sand down the ground spot very good until it is down to bare metal. Secure down the ground tightly using a ring terminal of sorts, and, if you have some, put some silicone around the ring terminal to prevent corrosion

don't use.a seat bolt find one that goes to the the frame sand the.paint from around it

I've had 0 issues using the seat, my voltage holds up just fine.

OK but it doesn't pinch either?
