Yep...If the factory grounds cannot handle an additional 40-60amp load..you have other issues.

 

one amp always leads to another. the most prollems with amps are usually ground related. take ur doubts and get a clue

 

Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the
vehicle chassis and to connect the alternator’s
positive connection to the battery. To prevent
voltage drops, these wires should be upgraded
to 4 AWG when installing amplifier systems
with main fuse ratings above 60A.

 

“My amplifier shuts off once in a while, usually at higher volumes”
Check your voltage source and grounding point. The power supply
of the 250/1v2 will operate with charging system voltages
down to 10V. Shutdown problems at higher volume levels
can occur when the charging system voltage drops below
10V. These dips can be of very short duration making them
extremely difficult to detect with a common DC voltmeter.
To ensure proper voltage, inspect all wiring and termination
points. It may also be necessary to upgrade the ground
wire connecting the battery to the vehicle’s chassis and the
power wire connecting the alternator to the battery. Many
vehicles employ small (10 AWG - 6 AWG) wire to ground the
battery to the vehicle’s chassis and to connect the alternator to
the battery. To prevent voltage drops, these wires should be
upgraded to 4 AWG when installing amplifier systems with
main fuse ratings above 60A. Grounding problems are the
leading cause of misdiagnosed amplifier “failures.”

 

any questions

 

His amp doesn't have a grounding issue.. what's your point?
I will tell you I honestly don't know, but I doubt the 250/1 has more than a 60A fuse.

 

at first his amp cuts out. usually means voltage drop......now since he wired it wrong it cut out, dont kno how it even ran with what he said was wrong. i posted what the manufacturer said , what is ur point? go nit pick with someone else bro

 

I wasnt trying to start an argument man, it came off that way a little bit. my bad.

 

cool. i just got home from work...lol i must be jumpy.. i usually only try to help if i am confident in what im posting. i dont know alot, i do understand jl though, so have a good day
