dual battery hook up

im hooking up a another batt to my system my main batt is a red top and the second batt is a yellow top i got a jl1000/1 and jl 300/4  amp 3 10 kickers and boston pros my headlights would blink when i turned my stereo up to sound level to 20 on my deck and i also got the cap 5 farad  hook up and  i just got a stinger pro  sr200 amp relay / isolator now i need to know if i should hook the ups up to the yellow top batt( optima) or leave it on the red top the way i have it hook up now  also on the stinger 200 relay it says to hook up the ignition switch which is on the steering whhel wire harness which i think its purple for a 1977 chevy 1/2 ton pickup      thanks robbierob

For dual battery information go here and for the 200 amp Stinger relay, just meter the PURPLE wire to ensure that it's switched. I thought the PURPLE wire on the older Chevy's was the starter wire. Jeff

ok thanks but now my jlaudio is hook up to the yellow top optima battery and is still making my headlight s act all my light dim (blink) when i turn my bass up  now i know it should do this i have a alumapro 5 farad hook up only to this amp i wonder if it isn,t working like it should  i guess i could try the 15 farad and i tested my main battery and they said that the cranking amps is about 100 amps lower than it should be now would this make a diff  to my system since i have only the jl audio amp 300/4 hook up to this battery     thanks robrob

The JL slash series are some power hungry amps.  A multiple battery setup will do absolutely nothing for your dimming problems if your alternator can't keep them charged.  You need an upgraded alternator- plain and simple.  Also read the sticky above about the "big 3".My ex once told me I have a perfect face for radio.
