need some assistance w/ rms

Hello, Currently im looking to install Two alpine Type X subwoofers (12'') with a Hifonics 2010D mono amp. the amplifier is rated at 2000w @ 1.5Ω, If the subs are wired parallel / parallel will the amplifier hurt them? I've been reading around and cant find a definite answer.

Are the speakers single or dual voice coil? What is the impedance of the coil(s)?? What is the power handling of the speakers?

Dual 4Ω RMS is 500-1000 peak 3000watts

you should be good just keep the gain and a low level, you are bring it to a 1ohm load and hifonics will give you about 1500-1700 rms from the amp you have. You should not have any problems but just in case you should keep the gains down.Can't be loud then don't have it.

What do you mean by "keep the gains down"?  All by itself that is really poor advice.  Please explain to this user what you mean and how they would properly set their gain for this application.

Well for 10+ YEAR I always have set my gains by ear but I got to be there to do that and I am not. If this advice is so bad Dyohn then you tell us as viewers of this forum the right advice for this problem, with only what he his to work with. That means 2 12" and the amp. Well I know what you are going to tell him get a smaller amp or upgrade the speakers. See I know what you are going to tell him. Im not trying to be a hard @ss but don't tell people that they have bad advice if you don't have none to give. Sorry to all the people out there that reads this. Oh yeah for to let you know something hifonics is rated in Rms not watts. But still only puts out 75 to 80% of that amps rating. Don't really know about alpines rating but I assume that it us about the same. But like I said I really don't know about that.Can't be loud then don't have it.

All you did is just summed up the loose ends of my post that is it. I know there is a lot of bad advice on this forum but does not mean you all always right. I don't have to prove my self to am one on this forum, I know how to set gains and install almost anything someone comes to me to install, If i don't know I do research like a true installer does. If you thank you know everything you don't sorry. I know you are a moderator at the forum but everyone has their own why of doing things. This is the thing the buyer has to know some kind of knowledge of what system here are getting if not they could be getting junk. But I am going to stop venting and just tell you that everyone is different. I don't know where you get your info or what knowledge you have and I dont really care to much. You don't say "sounds to me like typical amateur advice from someone who might be able to do a simple install but who probably doesn't know how to adjust an amp to match a speaker." because that is someone that thinks he know everything about car audio. News flash my friend every system is different as while as the car. Hope know one gets mad over this and kicks me off the site. If so nice talking to everyone and I will be back with a new name.Can't be loud then don't have it.

You have a lot to learn, and maybe some growing up to do.Support the12volt.com

sounds like you need to take your own advice. I love what I do and my business Vibration custum sounds is doing great, Never had a compliant on anything I did and I am going to keep it that why. Oh I like that YOU GOT A LOT TO LEARN, That life always whiling to learn anything new. But back to the post. Roblol if you want anymore info about this subject and need me to future you with any question just PM me so we don't have anymore people just stating things. If not then good luck with the system and you have a great day.Can't be loud then don't have it.
