Question . . .

[Boyle465 10+ year member]

Alright, I just installed my new subs and amp and it just doesnt seem very loud for how much power i am putting to it... I have 2 Fi Q w/ bp power 2 ohm and a kicker zx2500... wired the subs 2 ohm and set the gains and everything...

also i connected both of my stock batteries with combined has 1500amps... Do you think i am just not getting enough power to my amp? Or any suggestions???

what guage is ur wiring?

put more info on ur amps and subs.

when you combine batteries the amps do not double

They do if wired in parallel and the batterys have the same amperage rating.

the amp hours double not the amps out put it might raise a bit but it wont double

you blew the johnson rod in the amp

get a new johnson rod

i am running kolassus kable 1 guage, so recommending a battery upgrade?

do you have voltage drop?

 

[Boyle465 10+ year member]

no voltage drop....

That is wrong. I don't want to flood this thread about this, but when wiring in parallel, voltage is averaged (or stayed the same if the same voltage between sources) and current is added. When wiring in series, voltage is added, and current is averaged (or the same if the same amperage rating between sources).

The AH rating on a battery is directly related to how much current that battery can provide total. Take a 700 CA battery for example. If you dont use 700 amps, it will maintain a voltage longer. AH is rated at 25 amps/hour. So if you only use 25 amps, of course it is going to maintain a decent voltage for longer. It only makes sence that if the AH doubles, so does that total amperage output of the battery. Refer to an electronics book about wiring sources if you have any further doubts.

Whats the voltage at your amp?

Check all connections. A lot depends on install too, what box are they in?

No doubt the subs are in a less then stellar enclosure, as is usually the problem with low output.

If voltage drop or ampere supply was the issue you would be experiencing the subs cutting out, the amp going into protect, and/or

lights dimming.

Im pretty sure i came to the conclusion that it is my battery... I dont think my amp is getting enough power to put out its full wattage... if that makes any sense...

Check voltage with a DMM at the amp to verify that it is the battery.

Def check your voltage with a DMM to make sure, but if you are getting no voltage drops, then it's most likely not your electrical system at all.

You still havnt told us your box specs...
