my alpine type r so I got my alpine type r 12" 1222d today... dvc dual 2 ohm. I had a svc audiobahn. My amp is the rockford fosgate p5002 500x1 @ 4ohm / 250 x 2 @ 2 ohm When I hooked everything up, my amp kept shutting off within one or 2 seconds...getting extremely hot. Finally diagnosed the problem. I had wired it incorrectly, wiring it in the 2 outside pos and neg terminals (thus making it bridged) instead of using just one side the left or right..... finally got her pushing....sounds great! will post pics and review later |
Re: my alpine type r 5 Attachment(s) some pictures of the install and some other randoms.... working well now that I have it hooked up right....it kept shutting off since it was bridged and not wired properly... "haste makes waste!" |
Re: my alpine type r Very clean & simple setup I like! |
Re: my alpine type r looks good. simple and to the point, just how I like it. How do you like running one 12? I am currently running a pair of 10s and am thinking of goin to a single 12, mainly for space constraints. im tired of only having half a trunk. |
Re: my alpine type r single 12 is what I have always had...... the reason I love it so much is really that box......that thing is crazy...it will make any sub sound great |

Re: my alpine type r can anyone tell me why I can hear a high pitched ringing sound comming from the woofer if I get my ear close to enough to it? as soon as I turn off my cd player it goes away...whats with that? |
Re: my alpine type r 1 Attachment(s) this is how it is wired up....sorry for the terrible drawing.... is this the correct way to wire up a dual 2 ohm sub thus giving each coil 250 watts... the amp has that line and says bridged on it....i do not actually have something connected...I am just showing you what the amp terminals look like.... |
Re: my alpine type r yes thats right, but you need to bridge it on your amp. your + should go the far left |
Re: my alpine type r I don't follow |

I don't follow You should do it like Option 2 http://images.cardomain.com/sites/so...1_2ohm_dvc.gif The way you have it hooked up now your only getting 250W, you need to bridge it to get 500W bridge |-----| + - + - X ----X you need to run the wires from the sub to the X location |
Re: my alpine type r holy crap!! your still going at this? dang mang! |

Re: my alpine type r I am connected ti the sub exactly as pictures...however if I hook it up to the amp like you said (bridged) it will shut off within seconds and get extremely hot. Which is weird because my previous sub was hooked up to those terminals, it was a svc sub though.....what is going on? |
Re: my alpine type r well I am pretty sure I just fried the amp.....it shut off smoked for aabout 1 second...I could smell it....and I checked in the engine bay and saw that the main fuse blew from the battery....so I am hoping that it cut the power before any damage could be done...what do you think the chances are that the amp is still ok? |
Re: my alpine type r nice man....love those alpine subs...hit so hard |
Re: my alpine type r well it isn't bumping right now...I hope this fuse blew before the amp got damaged |

Re: my alpine type r i have 3...option 2 for sure.... what happened was me messing with the wires on the amp..i accidentally eaither revered polarity or touched something and it shut off and blew the fuse at the battery....now I wondering if the amp is fried...or can i just buy another fuse be ok |
Re: my alpine type r well the amp is officially done...fried.....close this thread! thank you for all the help guys.....need to get a new amp for my 1222d type r |
Re: my alpine type r good lesson learned......never make any wiring changes with power on. did you try to replace the fuse yet? |
Re: my alpine type r already replaced the fuse...the amp doesn;t even turn on now....i was hoping that it was a simple part thatneeds replaced...but I think I should look for a new amp.... |
Re: my alpine type r I just realized that the amp is in protect mode and tries to turn on how do I get it out of the protect mode |
Re: my alpine type r it goes on protect mode if the ground is bad, check all your connections |
Re: my alpine type r man this kinda happened to me. i had my 2 jl 12w0-4s hooked up in parallel to my 2 channel amp bridged at 4ohms. This caused a 2ohm load. Everytime my subs would hit hard my amp would die. Figured out the problem. Somehow i didnt fry my amp. Im so lucky. Ended up unplugging all the wires from it and lettin it sit for a few hours then rewiring the subs properly then hooking up power wires then turnin it on and it worked fine and im usin a crappy amp. That alpine is awesome. Its massive. But i say go JL or go home lol. |
