No, it's actually better and easier to connect your subwoofers together properly and use a mono amp.

Back to your initial question about CC being "reliable," the answer to that depends entirely on the people working there.  But in general, if you have a store install something and they do it wrong and it breaks, assuming you never messed with it they will honor the warranty.

I agree with the above comments about Cliff Designs, though.  A generally poor quality amplifier with highly inflated ratings that will not like operating at 1ohm very much, or for very long, without generating a large amount of distortion.

And one other thing: amps produce power.  Speakers create the "ohm" load.  Amps will produce power into the load no matter what it is, until they fry.  All you need remember when starting out is to never connect a speaker wiring configuration to an amplifier that will cause it to produce power into a lower ohm load than it can handle.  I suggest you review Ohms Law.

Wire the subwoofers together like the diagrams illustrate.  Connect that load to a mono amp.  Use a good quality amp like I posted above.  Using a two-channel amp for subs is a waste of power.  Waste is heat that is generated by the amp, where it takes a certain amount of power from your vehicle and outputs only half of it.  But for the speakers that you will eventually be putting into the front of the car, a two-channel amp is what you want.

Any more posts, list the model number of your subs and the air volume (post a link) of the box that will be used.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

also...sorry for double post but the amp u posted above puts out 400 watt RMS and the subs combined are 600 RMS
i wanna make sure they get enough power with a high ohm

For the $75 you'll spend on the box including getting it shipped, you should go over to the CC and talk to them about what they have.  It's better to see something in real life, although the box looks like it's okay (although it would cost me more to make a box than $40).

The subs are dual 2 ohm, which means your original post is wrong because you said each sub was 2 ohms.  And, shopping for speakers based on what they look like is crazy.  Go over to the CC and check some things out, now that we know you haven't ordered these things online yet.  Things can get out of hand very quickly when you are ordering online without enough knowledge to make good decisions.  Good luck.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

i wasn't shopping for looks im just saying i like how they are plain...honestly idc if they are ugly as long as they sound good and are decently loud
if they are dual voice coil and 2 ohm...does that mean each coil is 1 ohm?
also i found an amp at 600 RMS @ 4 ohm ..its the Phoenix Gold Xenon

DVC @ 2 ohms = 2 ohm impedance per voice coil.  That means the ONLY wiring configurations you can create with two of those are a total of 2 ohms, 0.5 ohms, or 8 ohms.  PG makes decent amps.  For two Alpine Type S woofers in a sealed enclosure I suggest any decent mono amplifier rated between 200 and 600 watts RMS into a 2-ohm load.  Go shopping and get help, do not buy on-line, especially since it appears you are a beginner and not sure of what you're doing.  That was not a slam, just an observation.  Cheers.

alright thanks alot
the PG was the 600.1 model
its 600 RMS x1 @ 4 ohm
600 RMS x1 @ 2 ohm
600 RMS x1 @ 1ohm
would it be good to go with that and just have it on 2 ohm?
thats the last question ill ask about it :)
