upgrade all 12v wires running to your system to 0 gauge to kill you wiring to small problem when dealing with systems bigger is better double check to see if you alternator is putting out enough power for everything just because it say it will doesn't mean it does upgrade your capacitor seems to be falling you because there made to store power when needed and also get your battery check for any defects and add and extra just for your system

How am I going to connect it to my car,Im wondering why it doesnt have a remote terminal like what the other capacitor brand had.

it's like a battery. you run it in parallel (run power from battery + to capacitor + then from capacitor + to ampplifier +) battery, capacitor, and amp each has its own ground (black or -). you don't need a remote wire. it only stores electricity until the amplifier needs extra juice (so your headlights won't dim).

What battery should i get for my 2008 dodge avenger. i have a kicker zx750.1 and the stock battery seems not to handle the amp's power. im not adding an extra battery.. i want to replace the stock...

hi, Optimer make a battery known as the "yellow top" which has a fantastic recharge rate. Unfortunately car amplifiers, especially ones running subs are well known to shorten the life span of a battery. due to taking large amounts of current at infrequent random intervals most standard batteries will have issues. In saying that the best solution for you is to purchase a reasonable quality battery and to install a min of 1farrad capacitor. the capacitor will stop the amplifier "power surging" your battery and lengthen the life of it.
i would try to install a 2 farrad capacitor even tho a 1 farrad will suffice as it should offer you more protection.
*added bennifit of stopping your headlights from dimming when your bass hits*
kind regards

I am purchasing a kicker solo x 12inch and installing it into a crown vic. can i hook it up like a regular sub power from batt to cap and amp or do i need to have an extra power source like another battery...

4Ga wire should be plenty for your application.
If you're concerned - run (2) lengths of 4Ga - its cheaper than 0.
A battery only extends the playing time of your system with the vehicle off.
Your car runs off alternator power - and it is recommended you upgrade the alternator to a High capacity one to properly supply voltage to your amplifier.
A capacitor is a cheap bandaid that will prolong the life of your stock alternator - but eventually - the alternator will die from the lage demands placed on it.
Put the battery and cap money toward a High Output alternator.

I have been having trouble with my car stereo system

First reinspect your power and ground connections, vibration may have loosened them.

Then be sure that amp location has proper ventilation, (overheating will cause shout down)
A 2400 in a closed space will definitely need exhaust fans to help circulate cool air around the amp.

The cap should be mounted close to the amp and properly charged before use. It is connected in-line with the main power lead paying close attention to the power in and power out terminals.

Power in = from the battery
Power out = to the amp

Good luck

Installing The Subwoofers to the amp... etc.

You should go with a 4 guage power wire kit. If your amp is going in and out
at high volume than that is your problem. 8 guage will work but, if you want
the proper current which is your power from your battery, going to your amp
than I would recomend the 4 guage amp install kit or just the main power
wire coming from your battery. If you would like contact me and I will send you
to a very good sight with all the info you will ever need for car amplifire installation.
