power problem

i have a Power Power Acoustik LT980/2 -- 2-Channel Amplifier max power 980 W rms 560W X 1(bridged) / 280W X 2(2 ohm) / 220 X 2(4 ohm).My subs are 2 rockford P2 10" 200W rms 400W max wired in parallel to give 2 ohms. I have a Power Acoustik PCNC-2.0F -- 3.0 Farad Digital Capacitor but my system with 1 amp dims my lights and sucks so much power that if i turn it up the vehicle jerks while driving. If the amp is wired at 4 ohms i don't have any of these problems. Can anyone help me. My car is a mitsubishi galant 1991 model.Prodigal Son

Sounds to me like you have a couple of choices.  1) wire your system for 4-ohms or 2) install a high-output alternator.  Actually depending on how you have your system wired your amplifier it is being overloaded as it is only rated to a 4-ohm load if it's bridged.Support the12volt.com

I had a similar situation with my power accoustic cap that was a pcnc-2.0f remarked as a 3 farad cap. It put more of a strain on the system then it did help it. I got mine of ebay and have no faith in the product. It was sold as a supposidly 3 farad, but you refference the part number and its only a 2.

Caps put more strain on the electrical system with the amp so best bet would be to sell it and save up for a HO Alt.

Thanx 4 the help really appreciate it. Think i'll save up 4 a HO alt as suggested. Any ideas on wat type of HO alt to get and where the best bargain could be found?Prodigal Son

Um what is the impedances on those subs? Single 4 or dual coils? New amp that will handle the load will further help your problem. Don't forget the big three.
