Im upgrading my amp to a kicker 1500.1 for the subs, and getting a 200.2 for my kicker 8s im putting in the door.

right now i have 4ga wire ran with a 150amp fuse. based on calcuations i have made, my new draw on power will be about 230. So i am putting a 0 ga kit in with dual amp support. with the leftever power cable, im going to do the big three up under the hood.

after doing the big three, do you think i would need a capacitor? I am thinking about trying just the big three and going from there, but just wanted to ask the question anyways.


next question would be how do you wire a capacitor with 2 amps? do you put it before the power distro box or can i just add it inline to the bigger amp since that will be what draws the power.

 

You don't need a cap.

 

k thanks

 

i've read all the back and forth about caps, and all i know is when i installed my amp for my mids and highs which puts out 125x4 rms, i was getting some dimming. i installed a cap, and it completely stopped.

 

Did he have the Big 3 done as well?

From everything I've read a cap isn't worth doing. I may be misinformed.

 

Using a capacitor is less effective than upgrading your alternator. You will see a much more appreciative difference by switching to an alternator that has a higher amperage output. I think the factory alterantors in these cars are very small.....something like 90 amps.

 

speaking about alternators...i got my windows tinted today, and i was talking to the owner about car audio. i asked him how to wire a cap and he too said to forget it. said the best thing would buy a car audio alternator or buy a second battery.



then he quoted me the alternator and i almost laughed at him. wanted 560 bucks for one that juiced 180amps...i was like well im going to install frist, then go from there.

 

Have you replaced the stock alternator with an aftermarket one on the 2008 xB?

I have one that's built for a tC sitting in my garage I got for $380... The pulley is too large and doesn't have a clutch. That's right, the stock alternator has a clutch or something in it. That's why it has the little snout on the front with a seal. I've already taken everything apart. Lol!

I received a smaller pulley from the place I purchased my alternator from, but it appears that it is still too large. I don't want to go through pulling out the stock alt and replacing it with one that may not work again. It's too big of a pain...

But I WILL have an upgraded alternator. a 3000 watt RMS amp needs more juice...

Also, capacitors are okay. I placed a Kinetik HC1800 under my passenger seat. All wire Kicker Hyperflex 1/0. Find kits on ebay for about 80 shipped.

 

yeah im using the kicker 1/0 dual amp kit....
