Hi! So I´m planing to buy my first BTL 18" in summer. The amp that i´m going to use is Alpine MRP-M2000, because I dont live in America, I live in eastern europe and amps like hirfonics or sundown are hard for me to get (only at ebay, but this includes high transport costs and i´m not very rich either). I´m right now upgrading my highs and mids and gona buy soon a new alternator so everything is getting slowly ready by the time. But one thing is on what i´m not so sure jet: should I get dual 1 or dual 2? is there all in all any big diffrence? and how i wire them? I´v read many topics on this forum already, but haven´t got any exact anwer.

My amp, what i´m going to buy:

2,000 watts RMS x 1 at 2 ohms

1,200 watts RMS x 1 at 4 ohms

Thank you guys!

get the dual 1. there are diagrams on here. im sure someone can post one on here if you dont know how to do it.

well if you consider "better" to be more power, then you would want to buy the btl with dual 2 ohm coils to wired in parallel down to 1 ohm. but to be honest, if you cant answer a question like that for yourself, im willing to bet you dont have electrical needed to support 2000 rms. you might want to do a little more research before you go ahead and buy that amp and sub. running 2000 rms for extended periods of time is going to require a high output alternator, a couple decent batteries, and 0 guage wire. and you really cant skimp out on buying electrical upgrades, or will fry your amp and possibly the sub. buying all that electrical equipment new might run you up to a 1000 bucks for 2000 rms. ive also heard alpine amps dont put out their rated power, but i cant say for sure. big systems cost big $$$

The amp is 2 ohm stable so you need to get the dual 1 not dual 2 but he is right that you need a good electrical upgrade to run something like this. on anything this size you dont want to go cheap on any part of it especially the electrical.

What the hell are you talking about Gioia69. He is going to need a dual 1 and wire it to 2 ohms. Also he already mentioned getting an HO alternator. So it sounds like he is going to be on top of his electrical. Don't forget about batteries. Example Deka, kinetik or XS

Not to bash another companies products, but this goes to all amplifier manufacturers that build large amps without a truly adjustable subsonic filter... stop it. You are doing a great disservice to your customers with ported applications. While the MRP M2000 has a selectable filter for 15 Hz (useless) and 30Hz (good for 33-34Hz tunings) you have no true adjustability to it for the other 90% of applications.

For this amp you will need the D1 coils wired in series for a single 2 Ohm load. Please tune accordingly and put the filter on the 30Hz setting. Do not use any boost on the headunit or amp either...

Thanks,

Scott

ok i thought also that dual 1, but is the soud qualty same like with dual 2? on the electrical side: I´m tomorrw going to order a 200 amp alt (i hope it is enough) and got a 78amp/h battery (for the car and highs mids) and going to buy one more for sub only? i think it is enough

I was planing to tune it somewhere in the 30-35hz range, so everything is ok? or should i realy consider buying some other amp

Thanks guys!

They seem to be Ok on the power side of things from what customers have said. Just the big issue for me is the lack of a good filter. if you tune 33-34 youll be fine with the amp set to 30 on the filter.

Thanks,

Scott

The only difference between 1 and 2 are the ohm loads

Ok its no problem i will tune it to 33hz and set the amp to 30:) then i´m fine

Thank you very much for that info, i realy would not have known that!!
