power caps?

I'm running a 10" sub in sealed box with an amp in my sei and was wondering is there much benefit of getting a power cap?
sub and amp are both JBL.
I have heard good and bad points about them but seeing as prices have dropped on them to the £30 for a new one i am considering one.
Also how do i ago about wiring one up?

Any opinions, advice and wiring info would be greatful guys and girls

Do you even have any power issues with the ICE?

Waste of time, money and effort. You do not need one.

i run 2 amps,sub,front and rear speakers with no power issues

steve1219 has then, girl at brooklans see them, she turned to her mates and says ooo wow hes got NOS

reminds me of when i had 2 power caps in mine, and some lads were saying look at them subs an 'wo that must be fast, 2 bottles of NOS' then the other one said, 'nah that aint nos its just two digital clocks'

cheers for the feed back. Saw and heard a friends today at santa pod and he's an ice expert from holland. he recommends them but think i'll save the cash.
cheers once again

Contrary to common opinion, power caps DO NOT sort any power issues. They only make the problem worse.

i found though that they do reduce headlights dimming which is what i need, when i ran power caps before the headlights dint dim so i need it sorting somehow

If you sort out the charging system (alternator, TB3, bigger battery etc) then that'll sort out any power issues

Even doing the big three they make a difference

see i like your replies steve ur either the devil or the angel u done the big three then?

i want it for mine but would prefer someone to do it for me *cough* *cough*

Bar for the alternator cannot make my mind up wether it is worth the hassel.

Steve

ur the one with the massive install

TB3 and a better battery are well worth doing if you need it
