so im finally getting around to finishing up my sound system. im going for a complete alipine system, so i have Type R 6x9s and Type S 4x6s. i have my sub box almost completely done (thanks to the sticky thread on the boxes), and now im picking out which subs i want. i am going for two 12" Type R's but i dont know which ones to get, the 4 ohm DVC or the 2 ohm DVC ones. right now i have a Legacy LA690 1000 watt amp im going to use but thats purely because of cost, and im thinking of getting an alpine amp sometime in the future (read: a really really long time) so i was wondering which would be better, if i want a good system now and when i get a new amp. i was thinking the 2 ohm ones, but im not quite sure if thats what i should be getting. if anyone has any suggestions i would be very appreciative.

 

it really all comes down to what your am can handle as far as "ohm load." 2 ohms are usually better for SPL (sound pressure level) but it depends how you wire them. in a series 2 ohms combines to a 4 ohm load but in a parellel circuit it ends up being a 1 ohm load

 

That amp can only only do 4ohm subs when bridged. So you should get the dual 2ohm alpines. This will work well once you get a decent amp, as they can be parallel wired for 2 ohm.

My only question would be. Why would you spend money on 2 decent subs and 1 really crappy amp? Instead of 1 decent sub and 1 decent amp?

 

If your going for sound, Get the 2 ohm subs and wire them to 1 ohm and invest in a better amp best amps for running 1 ohm are the mono amps

Question: are you set on doing a alpine amp if not I suggest hifonics (brutus series) they handle power great and most of their amps are 1 ohm stable, For your set up i would suggest this amp

And you need the BRZ1200.1d (the first amp listed)

 

sorry for taking so long all, but ive been moving, and starting school again, so ive been busy, sound system is done, i went with the 4 ohm subs, and mark fried the legacy amp, so i wen out and bought a 1000w alpine amp. ill put up pics when i get time, and which amp it is. it hits hard. so awesome.
