I have 3 Orion XTRPro 10" DVC and was wondering if anyone had any sugestions for an amp to push them. I was thinking JBL 1200.1 or Rockford bd1000. Also if I use a ported box the specs that come with the subs would be ideal correct?

I prefer the Rockford bd 1000 and it will more than handle it. Keep your box spec. within 1.0 cu.ft., 3" port Diameter and 14" port length. Try different boxs if you have a chance because you will get different result depending on the type of car and space you are working with.

I know the JBL is stable down to 1 ohm but I don't think the rockford is.  Most JBL amps I hate, but these from the power series are pretty sweet and they definitely give you more flexibility in general, as far as wiring the subs up is concerned.

In your current situation you're gonna be looking at a total impedence of 2.67 ohms and that rockford amp can definitely handle that anyways.  Both are very good amps in my opinion.  At that impedence the jbl will give you 100-200 more watts RMS than the rockford will--I don't know if that's important to you or not.

Both these amps are gonna need a fairly good alternator for them to run well, although the jbl will probably need a lil bit more current when pushed real hard than the rockford.  I'm not saying you're gonna have to run out and buy a new alternator, just that depending upon what kind of vehicle you have and what kind of load it puts on the alternator with just factory equipment, it might push it a lil bit.

I've hardly ever had any problems with rockford amps, especially the power series (and they have a 3 year warranty!!).  These new bd amps are pretty nifty.  If they are similarly priced I'd go for the rockford, but if you can save a couple hundred bucks by going with the jbl than that may prove to be a better option for you depending on whether or not money is an issue.

Go for the Rockford, they put out far more power than they're rated for (I have a Punch X1000.1 that's rated at 1000 Watts RMS and actualy puts out 1280 RMS). The signal is clean to but don't run it at 1 ohm or it'll run hot and fail soon!

Go for Rockford, I own a Bd 1000.1 its rated for 1152 watts full power at 2ohm, its running a single 12" Alpine Type R sub now at 1ohm and I never shut the amp down. Before my insurance claim it was running a 15" Alpine Type R and two 10" Type R. Even then the louder the music the better it sounded. Good Luck

Thank you for all of you sugsestions. I will be running a 2.66 ohm load do you think that the Rockford will be enough?

Yes the Rockford will be plenty, and will handle a 2.66 ohm load with ease.

I see a majority rule towards the Rockford amp, but the JBL is still a decent amp and a good bang for your buck. But with rockford you'll be getting more reliability and a cleaner signal. Proving that you get what you pay for. So if you're on a budget go with the JBL, if not...go Rockford.

cleaner signal???

you do realize that we are talking Class D amps here, not Class A/B...there is no such thing as a clean class D, or you would be able to use them to run highs too...

I would personally go with the JBL, because the BD series are pretty notorious for grenading...the powervalve also does the same power at 1 and 2 ohm, and will deliver more power at 2.66 ohms than the Rockford will...

do you guys not think that the JBL amps are somewhat underrated too? one guy claims 1280W, and I know the JBL puts out more than that, and the other guy claims 1150W...so what he said was almost irrelevant, because the JBL claims 1200W and is underrated as well...

unless you really hate the cosmetics, buy the JBL...it is a more powerful amp, and IMO more reliable as well...a bunch of the local salesmen are disappointed in the number of warranty claims and returns due to faulty product in regards to the BD series amps...

Only thing i'll say about the JBL Amps is 1 10" sub in a ported box 148.5 SP, Would you like to talk to the owner of the truck?
