i installed a pioneer head unit type s speakers and JL audio 500/1 to power 2 10" kicker comp vr's.i dont have my gain anywhere near the half way mark either!! my problem is that my lights in my dash flash pretty bad is the charging system on the TL really this poor?

 

get a cap to match the max power rating on the amp, change the ground wires, big 3, ground-chassis, ground-battery, ground engine......and id get a deep cycle battery.....


i have the cap on for now, doesnt do it often, depending on song and bass...but also be4 this car, had grounds changed, deep cycle battery and cap, and was fine

 

Battery and ground wires- thats you likely culprits

Everything runs off the battery's stored power, the alternator
just replaces what has been consumed by the stereo and
engine electronics

 

500/1 =

run a spare battery or get a 2+ cap.

 

No. Im running more than that and i have no problem with the stock alt, Optima Red Top battery and no cap

 

iono i have the 500/1 pushing 2 12w3v2

with a yellow top and 1 farad cap


every audio place i went to recommended to run a spare or get another cap.

 

i have a 900rms 2channel, 2 type r's with a 1.5 farad, and barely dims...on stock battery and stock cables...

 

to make more money!

 

okay thanks guys, my ground cables are i think 4 or 5 gauge and power is 3 i believe. I will get a new battery this paycheck and look into getting a cap.
do you just wire them in before your amp just in series?

 

get a new battery for good measure then go get at least a 1.5 farad cap. you should have no flicker after that. i ran 1000rms amp with a 1 farad on the original battery which is 4+ yrs old. it only dimmed if i had accessories on and bumped it above festive listening levels.

cap is wired in series with the feed line before the amp. use the charging circuit to get proper performance.

 

well since my lights do dim with my setup its either that or a higher output alternator to get rid of the problem

 

At idle the bigger alternator isnt going to solve your problem
They make the power above 1500-1700 rpm,
so the baddest battery you can fit is the way to go
