adams2003 Posted November 5, 2004 Report Share Posted November 5, 2004 I am currently looking into buying a couple 12" Rockford Fosgate Power stage 1 subwoofers for the SS, but im not sure if I should get the 2-ohm version or the 4-ohm version? In fact I dont even now what 2-ohm and 4-ohm means? Any help would be greatly appreciated. Thanks. Link to comment Share on other sites More sharing options...
fast4popper Posted November 5, 2004 Report Share Posted November 5, 2004 First off, what amp are you gonna run these off of? that would determine what version you want. to make it a bit more complicated, Ohms are a measure of resistance against the amplifier in this case, the lower the impedence of the sub, the more power the amp will put out, BUT your amp has to be able to drive the ohm load that you are showing it. So if you could tell me what amp you have and how many of these subs you are looking at getting, i will tell you which will be right for your application. I hope this helps you out, and just so you know, there are NO sonic differences in the 2.

Dylan06SS Posted November 5, 2004 Report Share Posted November 5, 2004 You need to pick your subs based on your amp or pick your amp based on your subs. A lot of people make the mistake of just throwing random components together w/o looking at ohms, impedence matching, or tone balancing, etc. Theres a lot of stuff to consider when picking audio components (home or car) just need to do your homework and make sure each component is optomized to work with all the other parts of your system Good luck adam!

backwardsLbeats55 Posted November 6, 2004 Report Share Posted November 6, 2004 if you are looking at buying two of them...you would probably want to get the ones that are dual 4ohm voice coils....then you can bridge it down to 2 ohms...make sure you get a class D amp that can run 2ohms to...if not 1ohm...rockford makes pretty good amps to...

If you have a pair of Dual 2ohm subs, you can run a .5 or 2 ohm amplifier load. ;) Link to comment Share on other sites More sharing options...
adams2003 Posted November 7, 2004 Author Report Share Posted November 7, 2004 Here's what im thinking about going with. Let me know what you guys think. Rockford Fosgate Power T15002 2 Channel amp 500w x 2 @ 2 ohms T15002 Which will power Two 12" Rockford Fosgate Power stage 1 Subs 2 ohms T212d2 Let me know how you guys think that setup will work. Thanks, Adam Link to comment Share on other sites More sharing options...
Xero Posted November 7, 2004 Report Share Posted November 7, 2004 IMO rockford stage 1's SUUUUUUUUUUUUUUUUUUUUCK. if you want a great woofer for cheap get some audiobahns, or some alpines nick p.s. im running just one ALUM10Q from audiobahn 10" subwoofer, 800rsm/1600peak. I bought it for 139 bucks. the amp im running is the audiobahn A8000T 400 watts constant/800 peak. the only problem i have seen so far is this sub is running @3ohms. dual voice coils. so amps go quick.

fast4popper Posted November 7, 2004 Report Share Posted November 7, 2004 Not to get into too much of a pi$$ing match as to what is better, just remember you get what you paid for. On that note, there is a reason as to why you go thru the Audiobahn amps so fast. I am by no means a Rockford Fanatic but I will say this, they do make a reliable product for a great price, what you are looking at is a decent setup, I would go with the single 2 0hm subs in that application. and bridge the amp to 4 ohms mono sure the impedence might be a little different but you will NEVER hear the 1-3 db difference and your amp will be ALOT more reliable. Just so that people know where I am coming from, I have been a Car Installer for over 13years, I am an Install Mgr and have been for over 4 years and I have achieved Master MECP certification, the highest Mobile Electronics Certification that is available (MECP). Also I took 1st place at the USAC Finals in the 601+ Pro Sound Quality class in 2002. If anyone has any tech questions please fire away, Also if you are looking for deals on anything let me know and I will see what i can do for you guys. -C- Link to comment Share on other sites More sharing options...
Xero Posted November 7, 2004 Report Share Posted November 7, 2004 im not knocking anyones setup, i just think the stage 1's suck and suck bad. there is much better out there for the same price. Link to comment Share on other sites More sharing options...

Now if you bridge a 2-chammel amp, you are correct- the load would be 1 ohm. My favorite was 4 8 ohm 8" subs all in parallel to a big old-school RF punch amp that was bridged. Yum.

I always bridge a sub amp, so I always speak as such, sorry for the confusion. If you didn't want to bridge the amp, you would still look for an amp that is stable at the same bridge loads I spoke of, so they will also be correct for 2ch operation.

Get me your address and I will get you a few pics. I have not changed the system since the Finals of that year, still wins local shows and this year I took Best of show PRO in a triple piont event in Wisconsin Dells. I would love to rebuild the car and have another go at it, but buying a house and having a kid have slowed me down a bit.

Actually, we both are. On a side note, you are wise to run sub amps in single channel mode, but I was just pointingh out options for flexibility, in the event he has already purchased the gear and needs some wiring options.
