need wiring HELP!
sorry this is pretty nub question but i dont want to mess up my system so thought of asking your pros on s2ki.com
I have a 4ohm dvc subwoofer Infinity kappa perfect 10DVQ and a Rockford fosgate p500-2 2 channel 4ohm amp how would i wire these together i know i can wire the subwoofer to a 8ohm load and a 2ohm load but is there a way i can make it to a 4ohm load or can i just wire to 8ohm wiring and put it to my 4ohm amp bridged? thanks in advance

i was thinking that t oo but wouldnt it run too low Watts these are the specs for the amp:
125W x 2 @ 4-Ohms RMS
250W x 2 @ 2-Ohms RMS
500W x 1 @ 4-Ohms bridged RMS
i just wired my woofer for 8ohm load to my 4ohm amp bridged at 4ohm 500w....but i kinda figured this is not safe for my equipment

Looks like your amp can handle a 2ohm load. Wire the DVC together in parralel and make it a bridged 2ohm load. All done!!!
You will risk the chance of over heating your amp. If you keep the gains down it "may" work but I wouldn't risk it.
2 options....
If sub is new....return it and find a 2 ohm DVC and run in series to your amp bridged or just run each voice coil to one channel as your amp will take 2 ohm in stereo mode.
If you can't return it...run your sub in series and run to your amp bridged as above or run each voice coil to the amp in stereo mode. You'll be running the amp in cruise mode since you will be above the rating of the amp but you won't have issues with the amp overheating due to a low impedance load like the quote above wanted you to do.
True you won't have full power from your amp but it will work for a long time.
Don't get the bright idea of just running 1 voice coil either to get the right load for your amp. DVC subs need to run "both" voice coils to perform properly. Parallel or series...either will work.

it's not 2-ohm stable *bridged*, only 2-channel.
if you wire your sub in series (8-ohm) and your amp bridged, you'll
get 250 watts (rather than 500), which may be sufficient for you and
is perfectly safe for your gear; otherwise you'll need a different sub
or different amp.

Please explain how is he going to overheat the amp if it is 2ohm stable?
2 ohm stable in "stereo"...not mono!!! 4 ohm stable in mono.
His 4 ohm DVC sub will be 4 ohm in both voice coils.
If he wires it parallel his sub will be 2 ohm: suitable for one channel....but his amp is 4 ohm stable "mono"....ie....excessive heat generated by his amp and possible early failure and faults.
If he wires in series his sub will be 8 ohm....safer for his amp but he will not get full power from the amp.
Best to replace sub to 2ohm DVC or get a new amp 2 ohm stable mono.
