I am hooking up 2 infiniti kappa's and want 500-600 watts going to each sub. I bought a fosgate 1000.2bd amp, the subs say they are at 4ohms, and teh ratings for this amp at 4 ohms, is 250, not 500, does that mean I'm getting only 250??? Is this the right amp for the subs? Thanks.

Please look at the link below.

Yes, you'll only get 250 watts at 4 ohms. You need an amp that is rated at the wattage you desire at 4 ohms.

 

ok, anyone with a suggestion on what amp to get? I prefer fosgate, please help!!!!!!!!!!!

 

That amp will do it. It just might blow the subs due to the fact it is a fosgate and is underated. But that amp will do just fine.

HI guys..I have a question also...I am buying 2-12" ALpine type r series and don't know with what amp to go with? Could you make some suggestions please. Thanks..

 

I would suggest the JL 500/1 since it is a ClassD amp and will easily pound those Type S subs.

I've had two people tell me different things, how would the fosgate amp I bought work, how would the 500*1 Jl amp work out if it is only 500 and I want 500 to each sub???????

 

Okay first off, you cant just look at the wattage numbers alone. The JL 500/1 amp is a class D and is a very efficient amp. It is a very highly rated amp. Many pros will for sure tell you to pick that over a similar RF amp. That amp is underated and probably can push about 600-650 watts rms, which will give you about 300-325 per sub. But like I said, dont look at wattage. I know people who have this amp alone with just two 10s or 12s that are hitting well past 140dBs.

The RF amps are good, but JL is better. If you still want pure wattage (which is not necessary), then get the JL 1000/1. But let me tell you I guarantee you will rip apart the two subs alone with the 500/1.

Do you have single or dual voice coil subs? It sounds like you have SVC subs. What I'd do if I were you would be to go out an get a good mono amp. The link you gave doesn't have a power rating for mono. Can you bridge that amp? If you wire your subs together you'll get a 2 ohm load. Now all you have to do if find a good amp that will give you the power you want at 2 ohms. I'd look into JBL (1200.1 like me) or Orion. If you like RF look into Lightning Audio. RF owns lightning and their amps are very similar in quality. The reason I recommend these over the JL amps that were mentioned is because the JL amps are mono. In order to hook up your subs to them you'll have to run your subs (assuming they are SVC) at 2 ohms anyways. You could pay $350 for a JL 500/1 or get a JBL 1200.1 for less than $300. At 2 ohms the JL will put out 500+ watts and the JBL will put out 1200+ watts. I have no idea how much a 1000/1 costs put I'd assume around $700 for probably less output than a JBL 1200.1. Sure the JLs have extra features that the JBL doesn't have, but you could put the money you saved towards a nice EQ and still come out with an extra $2-300. The JLs are good amps, don't get me wrong, but I personally wouldn't buy one unless I need the power at 4 ohms.

 

Yeah but you cant compare a 1200.1 JBL to a JL 500/1. That amp is not a ClassD amp. JL 500/1 is a much better better and cleaner. The JL is a high end amp. Not taking anything away from the JBL, but i think they are two very different class amps.
