this is the system that im planning on getting in about 2 months:"

2x Alpine Type - R 10" subwoofers, and a
Alpine MRD-M605 V12 Digital Mono Amplifier

The subs have 1500watts of max power and 500RMS watts each(i think) and the amp has a max RMX power of 600watts. Is this amp suitable for the two subs, and should i get an additional battery to power them, i think ive read about that before, just not too sure.

Also i need a place to buy a good enclosure for the subs, im looking to pay up to 200 or so for the box.

any help appreciated.

 

judging from the specs you list only, I'd say that's not enough amp for those subs. In fact, it wouldn't be enough to sufficiently power one of those subs.

Now, let's list what Crutchfield says about these components:

Type-R 10" subs

RMS Power Range (Watts) 200-500
Peak Power Handling (Watts) 1500
dual 4-ohm voice coils

Alpine MRD-M605
400 x 1 mono subwoofer amplifier

RMS Power Rating (measured at 14.4V):
Into a 4-Ohm Load: 400 watts x 1
Into a 2-Ohm Load: 600 watts x 1
Note: Minimum impedance is 2 Ohms.

With dual voicecoil woofers, you have two options for wiring...

2 DVC drivers with Voice Coils in Series / Parallel
Connecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 6 Ohms
Dual-4 Ohm Subwoofer: 4 Ohms
Dual-2 Ohm Subwoofer: 2 Ohms

2 DVC drivers with Voice Coils in Parallel / Parallel
Connecting the voice coils of each driver in parallel (+ to +, - to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances:
Dual-6 Ohm Subwoofers: 1.5 Ohms
Dual-4 Ohm Subwoofers: 1 Ohm
Dual-2 Ohm Subwoofers: 0.5 Ohm

Neither of these options yield an optimal resistance load for this amp... to make this amp work for you, you really need for it to see a 2-ohm load. With dual 4-ohm voicecoil woofers you just can't get there.

I still think this amp is too small for these woofers... they might work if they are dual 2-ohm voicecoil woffers, but I still think it's not quite enough power for them.

 

Amp x can always work with sub b, it just depends on what you are looking for.

The subs you have can handle more wattage, if you want to up the wattage on the amp. Or, if you want to keep it the way it is, you can do that too. You've got 600 watts (I'm guessing RMS, since you have max RMS) to feed the subs, and that is fine. You can give them more if you want them to be louder but it is not necessary.

You shouldn't need a new battery, it wouldn't help anyways. If you are having problems with your lights dimming, the you need a higher output alternator, but I doubt you have to upgrade your electrical system for this.

As for the enclosure, can't help you out there, I usually build my own. Costs about 30 bucks

Edit: just saw the previous posts, and unless those subs come in a different resistance, you are only going to be able to get about 300 watts out of that amp. Still will work, but only half the watts.

 

Yeah, I just checked, those subs come in different resistances, so you still should be able to get the full 600 watts out of the amp.

 

That set up would be fine. Since you will be using 1 amplifier and 2 dual voice coil subs, make sure you get the SWR-1021D subs. This is the one with 2+2 Ohm voice coils, so since we are getting technical as in the post above:
2ohm parallel 2ohm = 1ohm
1ohm series 1ohm = 2ohm
So, we have 1 amplifier pushing out 600W RMS @2ohms @14.4V
We have a load showing approximately 2ohms impedance (usually a little more)
Therefore we have 2 speakers getting somewhat less than 600W RMS @14.4V
You should be ok

 

Sure that amp can drive those speakers, but damn... why not give 'em a little more?

Alpine MRD-M1005
700 watts x 1 at 4 ohms
1000 watts RMS x 1 at 2 ohms

 

i want that amp but i dont have the money for that one besides i was planning on getting the 1021D subs so will my original amp be sufficient for the two subs since the 1021D are 2ohm-2ohm?

 

Yeah, it will wire up properly.

Actually, I bet those subs will take around 550 watts or so, so you could actually save some money and get only one sub and be just as loud.

 

...................I am confused
If you were to hook up the mrd-m1005 amp to 2 swr-1021d speakers (or 1041d for that matter) you will most likely blow them in a few minutes depending on how you hook them up. Sure you can hook the speakers up so it shows a 16ohm or even an 8ohm impedance, but what the hell is the point?
The reason that most car speakers and amplifiers operate at 2 or 4 ohms is simply because we are stepping up the voltage in a power supply from 14.4V to a higher voltage usually around 40V so we try and utilize the power. When you are operating a home theater system, you step down the voltage from 120V.
I stated above that you would get a little under 600W RMS per speaker if you hooked them up for a 2 ohm resistance. If the speakers are listed to handle 200-500W RMS power, why would you want to strap on a larger amp????

 

wft? ok, i dont know how much true information is in this.

1. You're speakers are not going to blow if you hook them up properly, even if you put them on a 1500 watt amp. On the contrary, you can blow your speakers by putting them on a 300 watt amp, if used incorrectly. Speakers blow when the user tries to push either the amp or the speakers too hard (ie. pushing the amp into clipping or giving the speakers too much power).
2. With 2 dual two ohm speakers, you can hook them up to the amp at an optimal resistance, not 16 ohms or 8 ohms, or whatever. You could, but that would just be dumb. You would be using the amp to like 1/4th of its potential.
3. The reason most car audio amplifiers run at 2 or 4 ohms is because a lower resistance means more power. Simple physics, P = V/R, where P is power, V is voltage and R is resistance. If you increase resistance, your going to reduce wattage, except for the special case amplifiers where they are designed to put out the same wattage at two different resistances. We usually don't see amplifiers go lower than 1 or 2 ohms because it is very hard to design an amplifier to work under that stress. Very easy to overheat at a small resistance.
4. This is a two part correction,
a. even if you were giving each speaker 600 watts, I would doubt they couldn't handle the extra 100 watts, and if they couldn't, all you have to do is turn down the gain on the amp, its that simple. Like I said previously, I could put a 1200 watt amp one of the speakers and not blow it, just by setting it up properly.
b. you aren't even giving each speaker 600 watts, there are two speakers so each is recieving 300 watts.
