Hi, first post to the forums, //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.
I have a friend who has a power acoustik 3000 watt demon amp for sale for $100 and he will build me a custom box for free. I was thinking I would get the Power acoustik mofo 15" dvc 4ohm sub to replace my now kenwood subs. The kenwood subs currently run at 400rms at 4ohms a piece(2 channel amp) and I have NO LIGHT DIMMING AT ALL. However my alternator is only a 85amp, so to go to a 1700w rms sub would fry my alt. right? Upgrading my alternator isn't within the realm of possibility(would cost me $600 for a ho).
So I have done my research and am wondering if I could get an answer on which of the following upgrades would be necessary to keep my alternator kicking(as well as my battery).
1. The big 3
2. Second Battery
3. Upgrading my current battery in addition to adding a second battery
4. Adding a 3 Farad Cap. to my system
5. Adding a volt-meter/regulator to my system
I am only considering upgrading because the amp and box are $100, and I could get enough for the mofo by selling my current setup. So please keep price in mind while giving me suggestions.
P.S. In the summer I go to a drive in theater pretty regularly, which has double feature movies, they let you charge your car for 30min in between films, so allow for that time just sitting(If I need to carry a booster pack I could get my hands on one for dirt money, not a problem...)
