In myy car I have a 0 awg wire running to my positive on my second battery and another 0 awg wire running from my ground with distibution blocks on the ends. Then I ran 4 awg wires to my amps...now is it true that the correct way to wire a cap is to have the wires from the amp ( + and -) run into the cap first than have another set of wires go to the distribution blocks or can I just wire the cap directly to the distribuion blocks..its all ran in parallel in the end so I cant see a difference but someone who works at the road shop in circuit city said its not wired correctly unless the amp it wired to the cap first..

Thanks in advanced!

 

how many amps do you have? and is your d block fused? The best way is to have the cap right next to the amp and ran inline on the power wire

 

I have two amps...one for the speakers and one for the subs...d blocks arent fused.

 

well you could wire it inline (off the power wire with a seperate ground) before the dblock

 

and it honestly makes a difference? Obviously I would wire it with the sub amp.

 

with a second battery the cap is useless.

 

heres mine



Wires goin up are to the amp and wires into the box are to the subs and then the 4 gauge blue wire is going to the battery

 

will it make a difference yes... is it that big not really but you can decide for youself what to do.

Anyway what a cap is or what a cap does is supply alot of power very quickly when the voltage at the terminals drops (so supplys it to the amp when its run off the power wire) Now the further away and the more resistance there is (smaller wire has more resistance, and any type of connector whatsoever has resistance as well) the less effective the cap becomes. Also if your highs amp would never use the cap (if it was inline with that amp only) then putting before the d-block is a complete waste

 

so basically best way would be to wire it inline with the sub amp...and why would a cap be useless of a second battery?

 

yes

reason why he said that is because the amount current a battery holds is alot greater then a cap so usually with 2 batteries your lights will never dim and most people consider their electrical system strong when the lights dont dim. I agree its good when the lights dont dim but in the same retrospect you could be running at 12v all the time and blow your alt or what not while not seeing much dimming. Personally i think caps do have a use even with 2 batteries but the problem is they are pricy and work alot better with a stronger electrical system... the problem with that is people with a stronger electrical system dont really need a cap (although it helps it doesnt warrent the price) and the people with shitty electrical systems add a cap and it doesnt work because the cap isnt made to be a battery

 

Yeah well I have a Redtop for a second battery and my lights still dim on heavy bass but im deffinetely going to put in my lanzar 2.4 farad cap with the power supply of my sub amp.

 

ive got my amps grounded to the chasis. from my battery goes to the fused d-block. then on end goes to the + on the cap to the subwoofer amp and the other side goes to the surround amp. my cap is wired to the + on the battery and - to the chassis.

 

Your supposed to ground your amps back to the cap and then ground the cap to the chassis. WRONG, I'M AN IDIOT! I MISREAD THE INSTRUCTION MANUAL!

 

no you are not

 

Look into special batteries just for amps. I got one that is equal to a 100 farid Cap and my lights do not dim at all. I am running a power hungry fosgate BD500.1 power series amp that pushs out 1050 watts RMS and peaks at 1800 watts. The battery goes for around $200 and is kickass. Here is the link to what I am talking about. You should for sure look into one of these and I promise you your lights will never dim again and you can get rid of your Red top battery and cap.

Also, there website will tell you that you need a more powerfull battery then what your really need. Like I said I am running 1050-1800 whats to my one sub and the HC600 battery is more than enough. My lights do not dim at all even if I put in a bass CD.
