justwitheraway Unregistered guest | Okay, I've been reading up on car audio lately and get the basics of it, however, Ohms screw me up. I realize the difference between parallel and series wiring but, what does Dual Ohm mean? I plan on getting 2x Alpine SWR-1242D Subs, or JL 12W3v2, but the "Dual Ohm" (2+2 and 4+4) screw me up. Can anyone please explain this to me. (Also which subs do you think are better, give me an opinion, I plan on getting an Alpine CDA-9853 Head Unit and 2 front speakers as well. I need amp suggestions also) Thanks. |

Amplifiers give different wattages at different impedancies or resistances. So with 4-4 you can wire them to 8ohm or 2 ohm and with 2-2 you can wire a speaker to 4ohm or 1ohm it all depends on the amp that you want to get. What amp are you lookin at. I have 2 alpine type R's and they are nice but JL makes great stuff depends if you want 1000watt amp or 600. |

justwitheraway Unregistered guest | Im not really sure what amp Im gonna use, I gotta figure out how Im going to hook up my 2 subs.. Any suggestions? Im basically looking for a great system so maybe JBL amp or something, but trying to keep the price down as well. Do you have 2-2 or 4-4 Type R's? And what amp do you have? If you were to wire 2, 4-4 subs (parallel), to say, the JBL GTO1201.1 II at 2 ohms running 1100 RMS watts, would this be 1100 to each sub or 600 to each sub? (I realize this is too many watts for either of the subs I listed) |

xdrummer03 Unregistered guest | To run 2 Type R in a parallel on one amp you need a 1ohm stable amp. Which is hard to get with a low THD. If your gong to do 2 Type R's.Get 2 MRD-605 amps. |

This amp for example. http://www.woofersetc.com/product.asp?0=295&1=296&3=2043 both sub will recieve there RMS of 500. |
