QUESTION:

if i hook up my amps and run the rcas to them but i dont put any speakers

if i raise volume and stuff would it still pull current and show a drop in voltage ?

Shocked

most amps draw about 1 ampere of current to remain on.. and they usually pull a small surge of current just to turn on as well.. after that small surge, current draw will remain at ~1A until you connect some subs to it..

UPDATE:

well from those who know me know that i always diggin up in my system especially when something not right.

so anyways like i said b4 this system not much different from the one i had b4 and wit only 2 spv70 my voltage would be between 12.5 - 13.2 and high volumes. my current system has 4 batteries and wont hold voltage not even at mid volume.

i tried everything from higher rpm, BIG 3 upgrade, cap *yes i tried the cap* nothing worked.i also test each individual battery and all were fine, so being me i scrap all the amps out so i could take a look at the wiring. so i checked from the amps go back and the only "problem" i could see was, the wire running from the alternator ran to distribution block where the batteries and amps were also connected.

at first i was like that should be ok then i started askin myself questions, WAT IF WHEN THE BASS HITS IT SUCKS THE CURRENT FROM THE ALTERNATOR FIRST INSTEAD OF THE BATTERIES ? that would explain the big drop in the engine rpm when the bass hits. thinkin bout that i also scrap all the wires and started fresh.

i ran the alternator wire to 1 battery connected all 4 like b4 and then ran the power wire to the distribution block where the amps would feed from. after i hooked everything up i bring my amps to test.

started the car to see a nice 14.4 on the meter chose a song that i knew always went down to 11.8....so i chose the song pause the music and crank it up to playin volume. and waited for the bass to kick in. to my surprise i when i checked the meter i saw 12.5 -12.7 nothing below. i tested a few other songs to make sure and the voltage is indeed holdin up.

the bass also songs alot more powerful and stiff now.

Shocked

would the level of your gains also contribute to the amps pulling more power ?
