Amp + subs? I'm debating which Alpine Type R's to get and I don't know TOO much about what Ohms mean etc. so I am currently stuck between the following:
2 12"
Alpine SWR-1222D (TYPE R)
2 Ohm
2 12"
Alpine SWR-1242D 12" Type-R.
4 Ohm
Both are 1500w Peak and 500w RMS... which should I go with?
Also what amps would you suggest with each one? I have around $300 to spend on the amp.

$300 should get you a decent amp.
Heres a couple, there are more but I gotta finish getting ready for work

You can also find Kicker amps on ebay pretty cheap.
You can buy either of those subs depending on the amp. If the amp runs at 1 ohm (stable), then you want the dual 4 ohm subs. If the amp runs at 2 ohm (which most do), then you want the dual 2 ohm subs.

They are dual 2 ohm VC, and if you have 2 subs you can bring them both to a 1 ohm, then connect them togather so that you get a 2 ohm load.

I am running 2 JBL power P1222 in my car with that amp, and brought down to a 2 ohm load, and its too much! You will be fine with that amp, and if you go bigger you will need a cap.

Unless you are thinking of this Kicker ZX1500.1, that 1500 watts RMS at 2 ohms. You would mostlikely need a new alternator, new battery and a 2.0 cap. And you would never use all that power.

Yeah, i can agree with that.
Eather way, cap or no cap, that amp the Alpine MRP-M850 should be plenty of power, also its under $300. What is your budget?

If you have an adequete alternator with good power wires and grounds a cap is uneccessary. I've never used one even with larger systems I've built. If I can't get it done with alternator power and big 3 upgrade to help make the electrical system more efficient...then I would rather use an additional smaller battery like a Kinetik over a cap.

A cap is no where near being called a battery. They are two totally different things.
I think the Alpine amp will be struggling for to power the two type-rs. Considering where gains should be, he'll probably be feeding them under half of what they can safely take. That is quite a bit of power (or lack thereof).

caps dont do ****. i have 2 15's in my t/a off a single JBL amp and of coarse the amp cant really do the setup justice. i have another amp on the way and am afraid it still wont be enough, so ya too much is a matter of opinion. i might do 2 18s, running 1k watts a peice and still no cap. like said, good battery/alt/grounds/power cable, you'll be fine. Big 3 would be good to do, i know my car needs it bad.
