I have a volkswagon polo with a 120 amp alternator i have installed a jl 300/4 with a fuse box and a fuse this works perfectly and a 750/1 with a 60 amp fuse powering a MTX 815-44 sub it is connected to a 1 farad capacitor. My problem is on installation of the capacitor with the 750/1 the fuse keeps on blowing when the volume is above 25 out of 63 max limit but when the capacitor was not there the fuse did not blow, also the bass seems to be less above the 20 mark this is where the capacitor helped but after a couple of bass notes the capacitor runs dry and the fuse blows recently on the day of the 750/1 install i had upgraded my lights from std 50/65 to 100/130 ones and the fuse blew twice when the ac and the lights were on at the volume of 25. My battery is 45din 45Ah rating should i upgrade this to 60-74 Ah ones? kindly suggest how i can tweak my system to enjoy the system i previously had a 1000/1 which was amazing so i bought the 750/1 for my polo.
Upgrade all 12v wires running to your system to 0 gauge to kill you wiring to small problem when dealing with systems bigger is better double check to see if you alternator is putting out enough power for everything just because it say it will doesn't mean it does upgrade your capacitor seems to be falling you because there made to store power when needed and also get your battery check for any defects and add and extra just for your system

You will need to have the amp bench tested at full load to see if there is a pending problem. It will need to see with speaker loading resistors, how much current the amp is drawing and at different frequencies. if the amp checks out with the proper current, at the rated output, have the speaker checked out. Good Luck

hi there r u running any other amps in the vehicle as well as the 1000/1?
SOURCE: jl audio 1000/1 low voltage -keeps shutting off at high volume
You should definitely upgrade the power wire to the sub amp to 4 gauge -absolutely your choking your amp its starving for current-poor thing is starving !!!!!!!
