Alpine Type R (SWR-1242D)

Looking into a mono Hifonics amp for my single 12" type-r. Would it be better to run a mono amp at 2 ohms or 1 ohms?? Would the amp heat up faster and draw more current from my battery at 1 ohm compared to 2 ohms??

I still find it hard to believe to put 1000 watts rms to a ALpine Type R 12 or 15. Seems like overkill and a easy way to blow the sub and heat the voice coils.

I whould imagine a Orion 600D or Kicker KX600.1 or JL 500/1 or Alpine or JBL to be better choice to match up with the Alpine. That Hifonics amp / BX1606d supposedly puts out over 1000 x 1 @ 1 ohm which im not sure is necessary for the type r's.

ANyone else here agree or do they think its fine ?

Is this for a sealed or ported setup ?

Well first off..obviously the amp will draw more current at 1 ohm and 2 ohms. Secondly, those Type R's are beastly subs. Their rated power is such a joke. Honeslty, If I wouldnt be afraid to through 1.2k-1.5k at that sub all day every day. Mainly power handling is gunna be dependient on the enclsosure, howver that sub can handle some power. Too bad I never really got to test how much it could handle.

just because your putting a 1000 watts on the sub doesnt mean you have to use it. on top of that there are tons of other things that go into power the enclosure impedance rise all kinds of crap. spend some time in the faq section reading about power ratings there just thermal ratings of what the vc can handle. like i said i put 4kws on my single execution and i ran it daily. yea uncanny is right! but it didnt like teh 4kws unless it was loading against something.

I had 800 on my friends sub and it never sounded better! Im sure 1000 is nothing at all those subs can handle alot of power

why would the shape of the box matter?

shape of the box doesnt matter that much it does to a point in spl but for this cause it wont have any effect.

If you are lookign to buy some Alpines you can buy off Ebay... they have great package deals. Most of the time you can get 2 12" for $260ish shipped

If your only looking for one then just get 1 but they are great subs and there is little to think about once u have it! Great sound and hits nice and hard even in 1 cuft sealed. If you were to port with a box that is 2.5 or 3 cuft at 30 hz it would be nasty
