I bought this sub about a year ago and I cant remember if its a Dual 2 or 4 ohm. go ahead and call me named I know im a *******, I forgot. right now I have it my ONE cvr. I have it wired to an old RF t500.2 at 300 RMS bridged at 4 ohms. so im guessing since I only have the 1 sub, whats the best amp to get for this 1 10 inch cvr? I hope its just the old *** amp because my sub isn't powerful at all and my buddy had one CVR also and his bangs hard. would the kicker zx. 400.1 work/.
