I have an alpine CDE-9874 head unit. The problem I'm having is that the subs aren't nearly loud enough, I actually can't tell if they're hitting unless I put my hand on them, even when I max out the amp and put the bass and sub levels to max on my head unit. I really don't know what I did wrong, so any suggestions would be greatly appreciated. |

New member Username: SneakyjesterMissouri America Post Number: 2 Registered: Jan-10 | the subs aren't moving much is the problem, I'll check the wiring anyways though, and while they may not be the best, they were a gift and I don't have the money right now to upgrade them. Thanks anyways. -edit- they're actually 1300w, but I doubt that makes much of a difference. |

Bronze Member Username: BoomboomboomNew Zealand Post Number: 11 Registered: Nov-06 | If the sub is a 4 ohm single voice coil model (likely if it's a standard Sony sub with 1300 watts max output)... something like the Sony 12" model XSL126P5B... then you'll hook up two of them like shown in the link below with a two channel amp (I'm assuming your amp is a two channel Sony amp something like the model XMZR1252. http://akamaipix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/2SVC_4-ohm_2ch.jpg It's a pretty straight forward setup with single voice coil subs and a two channel amp. One channel per sub. Those subs will be underpowered by that amp most likely. You'd be just as well off bridging the amp channels and running all the power to one sub. Like this diagram: http://akamaipix.crutchfield.com/ca/learningcenter/car/subwoofer_wiring/1SVC_4-ohm_2ch.jpg Try both ways and see which sounds better to you. |

New member Username: SneakyjesterMissouri America Post Number: 3 Registered: Jan-10 | Like I said they were a gift, so if you're going to tell me I bought terrible subs (-edit- apparently bad words aren't allowed here) off. I switched the wiring and that made it worse, so I switched it back. You're all going to think I'm retarded, but I trusted my friend knew how to set-up an amp, when I told him to blast it he actually turned it all the way down. Thanks for the help though, and I'll try bridging to one to see if it's any better, but either way I have a lot more bass than without them, so I'm happy. |
