JL 12w7 custom build
3 way front with two pairs of tweeters? What frequency bandwiths are you running each set of tweeters? Without proper crossovers and time alignment you are going to get some nasty spikes and dips with 8 point sources installed in different locations and aiming different directions. I'd just stick with 2-way passive until you can afford the processing.

The PRS mids are exceptionally flat up to 2k. Above that they get a little off balance, but people have been amazed at the very little EQ (sometimes none!) needed in the 80-2000 range. That should help you a bit, it will be slightly different for each individual install/situation but its probably pretty close.
yeah ive heard peoples systems with jl amps but when the sundown amp produces more than it says and when their custom service is that amazing... and let me tell you i have never seen such great customer service out of a company... also theyre cheaper. and theyre made in the US! 

Keep in mind, there are many class D subwoofer amplifiers out there that will do exactly what the Sundown does for the same price or less.

well after thinking about it and listening to it for a while, im taking the planet audio back cause im not getting nearly the full power out of the W7. im trying to find an amp thats close to 1000watts rms at 3 ohms. right now its only getting about 330 (if im correct).
can yall explain this tweeters and speakers stuff that yall are talking about. im trying to learn everything about this stuff but dont know much about speakers. i have alpine 5x7s and there alright. ive heard tweeters are completely pointless unless you put them in the right spot and get the right ones.

Actually both the SAE and SAX lines of Sundown are built in Korea...which would be the majority of their amplifiers. Still doesn't mean they are crap, because the new SAE 1200Dv.2 actually looks very promising. But don't knock something just because it ain't US built....

Its okay. My new speakers aren't made in the US, and they aren't that crappy. Seas Lotus = made in Norway.

ok well this weekend im gunna take out the planet audio and put in my mtx 600 for the time being. im gunna get prices on all the amps they have that are about the right rms and then post it on here to see which one yall think i should get and if none, then ill order one online. i hate going in there and getting stuff without look at prices online and confirming everything.

yeah thats what im trying to do
but what do you mean by electrical upgrades
is your goal to get an amp that is rated at about 1000w rms @ 3 ohm? if so you will have to invest in some electrical upgrades
That's going a bit far... he doesnt need a new alt or battery, just needs to upgrade the big 3, he should be fine. If not, maybe a capacitor or even better, a second deep cycle battery near the amp.
