Powering a Shiva?

[HBoB 10+ year member]

I'm thinking of getting a shiva sub fairly soon and the other day I was thinking that if I wire the vcs in parallel I would get a resistance of 4ohms right? If that is right then I would need a sub that puts out around 600w at 4ohms. The only reason I was thinking about this was that I narrowed my choice for a amp down to 2 amps, a JL 500/1 or a JBL 600.1, but if I have to wire the shiva at 4 ohms then I would need like a JBL 1200.1 as it puts out 600w @ 4ohms while the 600.1 puts out 300w @ 4ohms. Anyways could someone tell me if I am correct in this?

That's how I have mine rigged.

yes your are correct. I would go with the jbl 1200.1 so you can upgrade later.

K thx for telling me I was right about that. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I have one more question, with a JBL 1200.1 will it be too much for the stock alt in my 91 Buick Regal? My dad had it checked at work a few months back and said it was putting out like 120A or something...is that enough amperage to power that amp and not have my lights dim too badly?

That should be plenty seeing how the JBL's max draw at 1 ohm is 114 amps.
