Things are different in the car audio world now. Good car audio costs less now than it did 10 years ago but most all of it is made overseas, and many amps are made in China now. Lots of different brands of amps all come from the same few factories now, the only difference is there may be some variance between internal components. It used to be that the best amps were built here in the USA and the best head units came from Japan.
That being said, you don't really need 1700 watts of power from your amp. If using only 2 of those Rockford subs you should be fine with an amp rated at 150 to 200 watts stereo into 4 ohms. The power will be rated higher when bridged and that is fine too. Sure the specs will say it puts out 1000 watts peak power but that is not important. 50 to 150 watts pewr channel RMS stereo will be fine, plus the amp will be smaller than other higher rated amps. Get a good amp from a reputable manufacturer.
The Autotek amps from Sonic do very well but don't cost a lot. If you look at one you will see on the input and output ends it looks exactly like the Lanzar in your link. They come from the same factory in China but have different looks to the chassis. I had an Autotek amp driving front and rear Alpine mids and highs and a single Alpine 10" sub and it did fine, was good and loud and did not cost a whole lot, it was $89.00 from Sonic. I also like the Sound Ordinance amps from Crutchfield. SO is Crutchfield's house brand, some say they are built in the same factory that builds Rockford. I had a SO 4 channel amp for a while last year and it did a good job too. The downside to SO is they are pretty big, may be larger than what you are looking for.
Best thing to do on selecting your amp is talk to friends and see what they use and how it sounds, whether they like it. Read the reviews online and buy from a reputable retailer that has at least a 60 day return policy in case you want something different. Lanzar was popular here in Florida back in the day but I always thought they had about the same reputation as Pyramid and Legacy, not really all that good.
As for the dash installation kit you need a Metra 99-6503. If buying form Amazon, here is a link for it:
You can get the same kit from Sonic. Autozone sells it too. The amp installation wiring kit depends on the current draw of the amp. Sonic and Crutchfield both offer deals on amp kits and may even throw in a kit for free when you buy from them. The amp specs online will usually tell you what size wire you need, but you have to watch it. The Autotek amp I had recommended 4 gauge wire but the power and ground inputs were only big enough for 8 gauge. There are 4 to 8 gauge adapters you can buy but the amp worked perfectly fine with the existing 8 gauge wire I already have in my truck. Also be careful of the wire you buy, try to get 100% oxygen free copper. A lot of car audio brands use wire that is part copper and part aluminum now, I guess that is because the price of copper has shot up so high in the last few years. 100% OFC wire will deliver the best power but if you can find it it will be more expensive than the cheaper wire.
Talk to the guys in tech support at Sonic and Crutchfield, they can help steer you in the right direction. The best way to tell what to buy is by seeing what other guys have in their own truck or car. The Alpine mids and highs you picked out will do fine, Alpine speakers have a real smooth sound and are usually pretty high quality. The JVC deck has MOSFET outputs so will be fairly loud on its own, and they do sound good. I had one in my truck a few years ago. That is the other thing to consider, if using the deck power for your mids and highs, you will not need a 10,000 jiggawatt bass amp because it will overpower the mids and highs so you can't hear them. So you don't need a super expensive big power bass amp with that system.
