Pairing Subwoofers with Amp?

Hi all, I need opinion's on pairing 2 subwoofers with an amp I have, and want to make sure they are a good pair, so I'm looking at these.
https://www.crutchfield.ca/p_13610W0V34/JL-Audio-10W0v3-4.html and I want to pair two of these with this amp. https://www.cerwinvegamobile.com/products/mobile-audio/amplifiers/xed-amplifiers/xed1000.1m
I'm also gonna wire them to my amp for a 2ohm load. I just want to know if this setup would be ok.

I can't edit my post to switch my links to hyperlinks, but here they are. I'm a newb at forums lol.

Subwoofer

Amplifier

Look into the JL jx500/1d It retails for 200 dollars. It is class D and twice the power of the Class A/B amplifier you are looking at.

I already own the cerwin vega amp, I just wanted to make sure it would be good for the jl audio Sub's I am looking to buy, I have an Alpine MRV-1005 amp that has a power resistor blown and I want to get it sent out for repair, so I found that cerwin vega amp on ebay for cheap just to replace the alpine for now until I get it repaired, if it doesn't cost too much to fix lol.

Those speakers will work fine with that amplifier.

Ok thanks, I might consider getting the JL jx500/1d, I'm assuming you mean $200 us, it's around $400 Canadian from what I can see.

I also own a boss CXX1002 would that amp work with 2 jl audio 10W0v3-4, and how should I wire them? Should I bridge them, or wire them to each channel, but I don't think that's gonna work because it's 2 ohm per channel, but bridging is 4 ohm, but I haven't seen any wiring diagrams for this combination, but I seen that there's a diagram for wiring 2 4 ohm DVC subs to a 4 ohm load but not for SVC subs, is it safe to wire 2 4ohm SVC subs to a 4ohm load, sorry I'm a little confused with this, and can only afford to buy Speakers but I wanna match them with the Boss amp I have that's in another car because it's got more power than the cerwin vega amp.

If you use the Boss amp you'll have to wire one 4ohm sub per channel(not bridged) at 188W RMS according to Boss website.
It is not possible to wire 2 4ohm speakers together to a 4ohm load (only 2ohm or 8ohm).
If I had those amps I would use the CV amp wired 275w@2ohm because it's a higher quality amp and will most likely produce a cleaner output and is probably underrated where the boss is most likely overrated.
The JL jx500/1d would be a good amp for those subs.

why are you so set on those subs if you don't already have them? would you consider a different sub that would match the CV amp better?
What are your plans for a box?

I ended up ordering 2 of these pioneer's
And I figured the boss amp was alot more powerful than the cerwin vega, the boss website has the amp listed at 375w rms per channel, and the cerwin vega is listed at 275w rms into 1 channel, but I guess the boss amp may not be rated at that? Heres the links for the sites I'm getting the ratings from, boss amp CV Amp now since Im getting 2 4 ohm dvc subs it would be better to use it with the boss amp and wire them into each channel instead of bridging the amp and I should wire the subs for a 2 ohm load each correct? Or should I stick with the cerwin vega amp even though it's listed at a lower rms rating, but I don't get why they wouldn't rate the Amps properly, am i missing something? I'm still learning about matching Amps with subs and on a tight budget and wanna get the best out of what I already have, until I figure out my alpine amp I have which needs repairing, and the subs will be in a ported box and I believe it's 2.4 cu ft.

I went with the pioneer's because they were cheaper since I can't spend much at the moment, and they had really good reviews and also on sale, and I just realized I can't wire them subs for a 2 ohm load for the CV amp unless I wire them for a 4 ohm load but that amp only puts out 175w rms on a 4 ohm load so it's gonna be trying hard to push them subs and not sound good correct? so the only amp I have right now that is powerful to push them is the boss amp but like you say they over rate it? Why would companies over/under rate there Amps? Kinda frustrating when trying to match subs with Amps, anyways I already have a ported sub box, that has 2 jvc strobo subs and one of them is blown now and I had them for awhile with my alpine MRV-1005 powering them but the amp needs repair and I got the cerwin vega as a replacement for now, but then one of my jvc subs blew, so I was gonna get the jl's at first but I had to go cheaper, so I went with the pioneer's instead, so should I still use the CV amp or the boss amp for my setup?

After entering the Pioneer subs into WinISD here is my feedback.

The parameters of those subs make them more suited for a sealed box. If you get a sealed box or convert your existing to a sealed box then you will be safer running them with more power(Boss amp).

modeling 2 of them in a 2.4ft'3 box tuned to 40hz(i'm assuming 40hz because its common for pre-fab boxes) they will be much louder HOWEVER you are very likely to have noticeable port noise aka you'll hear huffing from the air moving through the port. This can be minimized by reducing the power that you run the speakers with. if you use those speakers in that box i would use the CV amp to reduce the noise and also prevent damage to the woofers. (this may be why the JVC sub blew?)

Most of the car audio brands depend on flashy marketing to sell their products(in regards to under/over rating). Even the CV amp says 1000WATTS MAX POWER!!!! so people will see that and think they are buying a powerful amp. They both are class A/B amps which is the electronic design of the amplifier. A/B amps are not very efficient and create a lot of heat as a result of the lost potential energy. Therefore the size of the amp's heat sync is a good indicator of how much power it will actually produce (more power=more heat).

The Boss amp will certainly put out more power than the CV just not likely to be as much as they claim and at the price of quality(higher heat=less efficient and higher distortion of the signal)....where the CV output numbers seem low relative to the physical size of the amp. Pick them up and let me know which one weighs more? This is a test that only applies to older (A/B) analog amps while the newer Class D and T amps are digital and are more efficient=less heat=less need for large heat sink.

Ok so basically the CV amp will give me better sound quality regardless of the power difference, and Tuesday is when the speakers arrive so I will let you know which amp weighs more and I'm assuming the one that weighs more is more efficient and powerful? And yea I believe the jvc's were only 125w rms each and I over powered them, but I got them used from a buddy of mine and had them for 2 years now with that alpine amp which is 600w rms and probably been over powering them as well. If I was to seal the port on my enclosure (not sure how to do that) and run the boss amp, would I get good sound and have louder bass as well? Or do you think no matter what just use the CV amp for better sound quality? Only reason why I want louder because I have Clarion door speakers and Tweeters and want the subs to keep up to the loudness lol, but I do want sound quality so again I'm guessing the CV amp is the way to go?

Weight has nothing to do with anything. Class D amplifiers are much more efficient than a class A/B amplifier. Class A B amplifiers weigh more because they need more heat sink to dissipate all of the extra heat they produce because of their inefficiency.

Do not get the jx500 for those subs. It is not 1 ohm stable, you would have to run it at 4 ohms. It will put out about 300 watts into that load.

Probably, however it most likly will not be as loud.

Probably more efficient not necessarily more powerful.

I stand corrected again:

That being said the pioneer subs have a relatively high sensitivity of 92db which I believe is an indicator of their response to the amount of power you provide them.
EXAMPLE powering a 92db rated sub with 100w will be louder than a 85db rated sub powered with 100w.
So they should get plenty loud with 275wrms @ 2ohm (see recommended reading below) in a ported box according to WinISD...if not loud enough for you feel free to experiment and use the Boss amp...Play with it its not that hard to swap the two amps out to see which you prefer before you get everything buttoned up.

Also there are other factors that we have not discussed like the voltage of the RCA output of your stereo, the RCA cable you are using(yes it can make a noticeable difference) and the power and ground wires you are using(Power/ground cable size)
It all can work together with different output/quality levels being the main difference in results.

Here's the head unit and my ground and power cable is 4 gauge, and not sure about the rca cable, so from what I've read I can use 1 voice coil on the subs and wire them for a 2 ohm load to match with the cerwin amp, and if it's not loud enough I will have to try the boss amp, but I'm wondering if I should run 2 channel mode on the boss amp instead of bridging it (or would it matter?) and wire each sub to each channel, the enclosure has wire terminals for each sub so I could do that, but like you say I will have to experiment with it, I'm definitely gonna try the cerwin amp first because the boss amp is currently powering a single 12, in my other car but if the boss ends up being a better candidate for the 2 pioneer's I will put the CV amp in with the single 12 and then I gotta rewire that sub for the CV amp lol, alot of messing around but I'm learning more about this stuff, I've always loved audio and wiring stereos but honestly never really learned about matching Amps with Subs and enclosure's.

I think that would be perfect for you. You can go for it!
