Diagnosing a stereo problem.....need help

[MO_GUY]

i hooked up my friends system today....and added a capacitor, the capacitor is a 1 Farad bolt series lightning audio, the amp is a hifonics 1000D, stock head unit and the whole system uses 4 gauge wiring....the subs are audiobahns wired for a 1 Ohm load, and we used a line converter for the RCA's....the capacitor is grounded to the same spot as the amp and when one of the RCA lines are unplugged from the amp the subs get louder, they hit way harder.....but then turn it up too loud and the capacitor all of a sudden discharges or something and starts to beep....then the system turns off and the capacitors voltage goes up again......what could be the problem?

A line converter is used when the head unit's RCA's are not present. You tap in to the speaker lines in front (or back) and then the RCA goes out from the same box.

These are all stupid questions but might help

im sure you have all the right wires spliced correct?
What kind of box is he running sealed, bandpass?
also did yall make sure that the wires running to the speakers were all hooked up correct? like + to + - to -
also how many speakers to how many channel amp?

as for the cap, it sounds to me like to much heat is running to it and turning it off, then the amp goes to protect... but i thought that a cap was supposed to protect that from happening. I have not dealt with capacitors, so i have no clue, maybe the ground isnt getting a good connection since its running on to of the amp ground?!?!

You stated when one of the rca's are unplugged the subs get louder, Do both subs? shoul one sub not work since you unplugged the one rca connection? I had problems with my line level converter and had to pull one rca halfway out in order for it to sound better and it was hooked up correctly.
