JBL mono amp with 2 subs

I recently asked about the Profile amps, and got great feedback.  It was suggested that I get a JBL BP1200.1 or BP600.1 .  I've decided I can probably get enough money to buy maybe the 1200.1, but more likely the 600.1 .  Anyway, I am confused about how to wire the amp.  I found a few other forums that touched on using one amp to power two subs, but I didnt really get the information I needed.

1.  When wiring a mono amp to two subs, how do u connect the speaker wire to the amp?  Do you solder the positive speaker wires from both of the subs together and the negative with the negative and then connect to the amp?  That wasnt a very good question, but would you in essence, put two seperate speaker wires of the same polarity into the same terminal?  How will this affect the impedence?  Will this cause the amp to over heat?

2.  The Rockford HE2s I'm looking at (RFP3212) have dual voice coils.  I read that the nominal impedence is 4 ohms.  So can I run 2 ohms into each of the subs?  If so how?

I'm sure you have noticed that I'm basically lost.  I just basically want to hook up two subs to a mono amp, if possible, and get the most power out of them.  Please answer any of the questions above.  Any info or suggestions as to what I should do are greatly appreciated.

I believe that amplifier is 1ohm stable this would probably be the best connection for the amp and the subs listed above

This would give lowest impedence being 1ohm and most power.

Sorry wrong format

All that information helps a lot, thanks.  I'm now lookin more closely at the 2112 Punch HX2 that wvsquirrel suggested.  If anyone knows of where I can get the subs or the amp fairly cheap please tell me.  You can email me at Ziggy1515@aol.com if you have any info.  Also, I'm thinking I might need a cap.  I read a great article on this site before explaining the necesity of a cap, I'll have to read it again and see if I really need one.  Thanks again for all your help.

I hate to be a smart ass but I just want you to make sure you're getting the right info.  First let me state that for most amps I would agree 100% not to risk running them at 1 ohm, much less 2 ohms.

However, if you take a look at the owner's manual for the BP series amps (including the 600.1 and 1200.1),  you'll see that the minimum speaker impedence is 1 ohm.  As it notes, there is no increase in power output past 2 ohms, so being 1 ohm stable is really just a wiring flexibility thing.

If you just go to the main product page where it gives you a summary of the product info, it only lists power output ratings for @ 4 ohms and @2 ohms.  Maybe this is what wvsquirrel was referring to.  Because there's no increase in power output below 2 ohms, I guess they don't feel the need to list the power ratings for 1 ohm, but do be aware they are 1 ohm stable.

I have actually seen these amps run at less than 1 ohm, but obviously in your situation there is no need to do so.  I can guarantee you though, that they will be completely stable at 1 ohm.

HX2s vs. HE2s:  That decision is basically up to you, and one way to look at it is that you could get the HE2s and use the money saved from not buying the HX2s, to upgrade to the 1200.1 amp.  On the other hand, the HX2s are a little higher end than the HE2s.  Keep that in mind.

But do keep in mind that the 1200.1 requires significantly more current and requires you to step up to a 150 amp ANL fuse (unless you can find a 120 amp fuse somewhere), at least 2 gauge power/ground wire, etc.  According to the manual max current draw for the 1200.1 is 114A, and for the 600.1 is 57A.  You can still use 4 gauge power and the more common and much less expensive AGU-type fuses with the 600.1.  I have seen these amps run and they do use a whole lot of power so I can vouch for those specs.  Sorry to throw another variable into the whole equation but I wanted to make sure you thought about all the advantages and disadvantages of both amps and both subs.

OK, once again my plans have changed, but I'm sure its for the better.  It is very unlikely that I will run 2 gauge wire anytime soon (thanks to esmith69 for informing me), I currently use 4 gauge.  Now if I was to get the BP 600.1 and the new Rockford HE2s (RFP4112) which have dual 2-ohm voice coils, would it work out?  The 600.1 will put out 600 watts RMS @ 2 ohm, which to me means 300 watts RMS by 2 at 2 ohms (please correct me if I'm wrong).  Does anyone have any opinions on these subs?  I was kind of leanin towards the 2002 models, and perhaps even older because I figure I can get them cheaper and I have also read a lot about them and they seem to be fairly reliable.  Maybe I didn't look hard enough, but I didnt find any HE2 subs with 2 ohm voice coils except these.  I was kind of set on the HX2s, I was gonna sell some stuff I have around the house to pay for them, but it doesn't seem like it will work out for me with those subs if I have to upgrade all my wires and fuse, I think the HE2s and one BP600.1 may be more reasonable for me.  Any suggestions on the subs though?  In your experience, what are some reliable, and hopefully fairly low cost subs?  I'm glad I didn't buy anything yet, I still have an open mind as to anything you suggest.  The people writing have been a great help so far, thanks a lot for your time and consideration.
