amp Impedance vs resistance of sub
Hi.
I have a lil problem, im interested in buying PHOENIX GOLDŽ RSdC 102 10" RSd COMPETITION SUBWOOFER as my new sub.... the thing is im currently running jl 500/1 its minimum impedance is 1.5 ohm, the sub has two 2 ohm coils... if i connect in series im going to loose lots of power, when parallel i think it will fry the amp.... what can i do? (beside looking for another driver), i was thinking if i connect my current Visonik 12inch which has two 4ohm coils, and connect both drivers in parallel i will get total of 1.5 ohm resistance, but i might be short on power (Phoenix is 600rms + 450 rms of visonik might be not enough for 500/1 which ive heard can pull 603rms)...
P.S. What r your recommendations of how to put that jl to good use (what driver will be best at reasonable price)

The / amp is going to make full power from 1.5 - 4 ohms so find a sub that is in that area and sit back and enjoy. It is not going to like 1 ohm so I would not recommend that. I would also not wire together the two subs together at all.
What is the goal with the new sub, why not find one that is right for the application?

Whats do you mean "right for the application? ... i asked for any recommendations so if you have any pls share... also if the amp puts up all the power in that range (doesn't make sense imo) then the sub is still good with serial wiring (R total =4ohm) ??

Yes the dvc 4 ohm sub will work fine. Right for the application means to purchase the right sub for the application, know it's capabilities and limitations, box requirments, budget etc. There are many subs on the market today that offer a whole range of different capabilites. The JL amp is a great amp, it was designed from the outset to provide maximum output across a whole range of differing impedences.

well i think the Visonik im using is quite over powered with that amp... i was looking for hours, double referencing you tube videos to see how they actually perform... i couldnt find anything other than this one that would be better then the Visonik im running (which i bought for $110 after taxes two years ago)... i did try rockford ported 10inch, 12inch pioneer and i was not impressed... and i dont have space to put more then two subs in my trunk so im not going to buy a pair... and my budget is very flexible, but im not going to overpay on some overrated brand drivers... and im not doubting you on anything but happens that there has to be correlation between resistance and power output (P=V^2/R) since the voltage can be assumed constant... the power will drop when resistance is increased.... again this is just on what my opinion bout this is based.... again ill accept and look into any suggestions... maybe personal experiences if anyone here was/is an owner of jl 500/1 and what can be used with it....

Your answer should be simple and no more than two sentences (what would make it good enough)

I believe I read somewhere that Phoenix Gold amplifiers are designed a little different than most amps. That is, they make full power into a wider range of load. I would assume this accomplished with a very UNregulated power supply?? The rail voltages must change with the amount of current being drawn. Dont know, but aparently they are quite unique, and if I were you, I would run the coils in series.

Like MR2NR (and JL Audio) stated, that 500/1 amp will output 500W into 1.5 to 4 ohms. If you were to wire the voice coils in series, you'd end up with a 4 ohm load, and consequently still have 500W available. Now that's 100W less than the RMS rating on the sub. But 500W can still get you very good bass when the sub is in a properly built enclosure.
Rated Power: 500 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V)

To Lazy Luke. You need to read an owners manual dude. You have an amp and you have no idea how it works. If you want help we'll give it to you, but don't ask the experts and then tell them they're wrong when you haven't put in due diligence. If you'd read the manual you never would have had to waste our time.
