I have a question regarding a 2 farad capacitor that I recently purchased. (i know everyone here is pretty much against caps) After installing the cap it seems like my lights dim even more when the bass hits. I replaced two 1/2 farad caps that I thought were defective as they were about seven years old, but they seem to perform better then my new cap. Is it possible that I got a defective 2 farad cap thats just straing my electrical system more? Thanks for all the help

can you afford a High Output Alternator and a good battery? i think it would work better than caps

OK, now instead of telling you to buy a high output altenator I'll try to answer your question. Its possible you have a defective cap, but you have to remember that if your charging system couldnt keep up with your stereo before, all you have done is add another draw onto the already strained charging system. What that means is that the cap is PROBALLY fine, the car just cant keep up with everything you have added on.

Big three first and see if that helps a lil. Then go for the HO alt.

thanks for the replies guys. I probably should give a little more info to my situation. Everything I have done to my system has seemed to backfire. I replaced all my stock 6x9's to have more volume range, only to have them be louder then the stock speakers. I put in a four channel amp and turned the gains all the way down to help a little. Replaced my old excelon amp that was pushing my new L7 because it was bridged @ 2ohm and the amp wasnt supposed to run like that.(although it worked fine and pounded) Purchased a mtx ta7402 super amplifier which sounded good but was a power hog (class a/b) which I thought was the source of my problem. I redid all grounds, etc. Redid all power cable to 4 gauge, bought an optima yellowtop that didnt fit my car, so had to bring it back a get a red top. Tried uprading the big three but my car has a seperate voltage regulator that I cannot locate. Its an 05 sebring so everything is as crammed into the engine compartment. Tried purchasing the 2 farad cap to resolve the issue but it just made it worse. Replaced my amp with an mtx class d mono block hoping to be more efficient which helped a little but not much, and I have had trouble locating a h/o alternator for an 2005 2.7l sebring sedan. I also tried moving the ground point of my amp so it shares the same point as my cap which didnt help either. And finally i upgraded my interconnects with a 17ft stinger helix because my old monster rca's were about 7 years old, and now i swear i have a slight echo on my bass. And finally I dynamated my entire trunk and doors only to find that all my rattle has been coming from the fiberglass hang over from the bumper. Sorry about the rant, but everthing has back fired and I appreciate any help I get from you all.

Sorry to hear about the troubles, trust me it happens to everybody sometime. But on another note if you don't want to spen a large amount of money on a ho alternator this would be an option. Look in the phone and find an automitce electric shop. Givem a call and see if they can re-do alt. to a higher amperage, I have a shop locally that has re-done a few for me with good results. The lst one I had tweaked cost about $100 for a 160 amp. Make sure it comes with a warranty and see if they test it in-house to verify the amperage. The shop I use is set-up with a computer, where you get a print out of what the alt. puts out, like a little dyno sheet.

Thanks, I will look into that. Seeing I cannot find a ho alt for my vehicle that would be a great option. Its just strange that I am having all this problem as I am only powering a single 12 sub, and the amp is 800w rms @ 2ohm you wouldnt think that it would require a whole lot of power. The amp has 90 amps worth of fuses and the ta7402 I replaced with it had 105. I am going to try and figure out how to upgrade my big three this weekend and see what happens (if i can only fins the voltage regulator)

800 rms is a strain for a stock electrical system.

You should take out hte capacitor and try a kinetik battery. It works better all the way around. You have different sizes a hc 600 equals 100-1 farad caps and this is the smallest one they make. www.kinetikpower.com to find a dealer in your area.

you dont think this would put more of a strain on my alternator. If not i'll order one up and try it.

Kinetik power cells are nice, I have installed a few with great results. The down side is if your willing to shell out $200 (HC600) for one of these, your better off getting a the alternator upgrade. Any knid of storage device is a temporary fix to a permanent problem-your charging system can't keep up with demand.

I have not had any problems with them and no they did not out any type of strain on my charging system.

I am either gonna order a batcap 800, or a kintetik hc 600. Which would say would perform better. I was reading the batcap installation instructions and I seen that they say you have to run the ground from the battery. Is this right? does anyone know if the kintetik is the same situation? I have tried six HO alt places and not one makes a alternator for my vehicle. I am checking into getting my stock one redone

No you don't HAVE to run the ground from the battery...Guess is that they say this so you don't mess it up and for sure have a good ground.
Plus it is just a waste of money and wire to ground it to the battery.

So is everyone saying that the batcap is a better choice then the kintetik battery?

I'd go kinetik.
