Is he getting one or two subs - it somewhat matters as the choice of subs determines what type of amp will work with them.
SWR-1222D - can run at 4-ohms or 1-ohm - There aren't any 500W 1-ohm amps, Class D amps that are 900W at 2-ohms, 500W at 4-ohms are expensive, 2-channel bridged amps can work and are reasonable.
SWR-1242D - can run at 2-ohms or 8-ohms - preferred, something like an MPR-M500 among others would be perfect.
SWR-1242D - can run at 4-ohms or 1-ohm - Profile AP2000 would be good for 4-ohms, Hifonics BXI-1208D or Sundown SAE-1000D would be good (and preferred for 1-ohm), probably most cost effective.
SWR-1222D - can be run basically at 2-ohms. Alpine MRP-M1000 or similar would be good.
Hope This Helps!!!

speakers, no amp, no subs
Hopefully this will help:
mikey91:yeah, we're going to run two of them. so i figure we need to put about 1200 watts at the most through them right? But can those 1242's be ran at 1-ohm?
Yes, I wouldn't go over (or much under 1200 Watts RMS).
Yes, you can run them at 1-ohm:
From your PM:
If I got two SWR-1222D, how would I be able to use the Alpine
MRP-M1000? It says that I could use a 2ohm sub or parellel two 4 ohm
subs to make a 2 ohm load. So if I were to use the 2ohm, would i just
wire them seperate, then put both into the speaker terminals? Please
help, I am so lost when it comes to what amp to choose for Ohm loads.
You want the 1242D's then.
Regarding the bass knob - it is handy if you like to adjust the bass volume a lot for different tracks/music types.
If you just want to turn the bass OFF sometimes, you can use a toggle switch on the remote wire to the sub amp.
If you don't like the looks of having the switch, you can often control the subwoofer level through the HU, but sometimes the setting is buried in two or three levels of menus.
It just depends if you will use it, and what your other options are.
mikey91:what is your opinion of the Hifonics amp we were talking about and the MTX Jackhammer JH1200? cuz i want a really good amp, and i haven't really seen any reviews for the Hifonics, and i know the MTX is pretty good.
I didn't realize the MTX was 1-ohm stable and CF carries it, so I have to watch what I say...
MTX has a great reputation and I'm sure it is a good amp. It is also at least double the street price of the Hifonics, I believe. There have been members on here that said the Hifonics worked better and was preferred over the Kenwood amp they replaced with it. All that aside, if you really want a high-quality amp for the subs and the MTX price isn't scaring you away, there is a member that really likes the Sundown SAE-1000D, so I would look at that next.
If the Hifonics is a good reliable amp and has good a low pass and high pass filter than that is most def. the one i'll get.
I haven't checked, but I would be amazed if it lacked a low pass filter.
Exactly why would you want a high-pass filter on a subwoofer amp?
Box type depends on what you listen to, but see this thread.
I think someone asked that before, ummmmn,
Short answer is "No, I don't".
Anyone else have suggestions?
I read that more super glue doesn't work as well as a little.
There is actual mirror adhesive, but not sure what to do if that isn't holding.
Because my name is on the business, I work hard to make sure you get the best possible shopping experience. I look forward to hearing your comments .
