New member Username: Brent113Post Number: 1 Registered: Sep-07 | I have a 1991 Civic hatch with a ZC engine swap. I'm also putting in 2 12" cvx's and a 1700W amp. Obviously this means I need a new alternator. So I was looking around at sites like 4alterstart and found this: http://www.4alterstart.com/pages/store/skudetail.nhtml?profile=highoutputalterna tors&uid=10136&returnURL=http%3A//www.4alterstart.com/highoutputalternators Is there anyway to make this (or something similar) work in my car? Either as a replacement or a second alternator. I've been researching a lot but I'm not sure where I can find a bidirectional fan or how to mount it right. Any insights? |

There is room for another alternator where the ac was mounted, but it needs to be ccw or bidirectional, which I haven't found yet |

New member Username: Brent113Post Number: 10 Registered: Sep-07 | That's a good point. I actually just received the amp in the mail today and was windering something. The amp has 3x35A fuses (105A total) and is rated for 1200W at 4 ohms, 1700 at 2 ohms, and 2200 at 1 ohm. How does that work? I didn't know you could create power!?! I mean, using p=iv 105 amps at 12 volts is 1260 watts. |
