First real system, need some advice. Alpine and JL.

First off hello, my name is Drew and I am from Missouri. I have been into car audio since before I could drive. This will be my first higher end stereo. I know forums get questions like this all the time, so sorry in advance.

Here is my current setup. I have a 2008 Mitsubishi Evo X with the Rockford Fosgate MMCS system which includes a 7’ touch screen with nav/dvd/cd(with a hack I am able to watch dvds in motion ), 30gb music server and a RF 10” sub. Doesn’t sound too bad but I definitely want something more, and I am finally in the position to replace it with a higher end system. I am going for a mix of SQ and SPL leaning towards SQ. My plan is to remove the factory amp and sub leaving the touch screen and nav/dvd/cd/music server. First off I am an Alpine and JL guy so I am pretty much set on those products. I plan on replacing the stock amp with an Alpine PDX-4.100 for the fronts and rear, an Alpine PDX 1.1000 to run 2 JL Audio 10w7s(I may end up with a single 13w7 for space reasons) in a custom vented box. I will be using a JL Cleansweep to help with the signal from the factory headunit to the amps. I am going to leave the stock front and rear speakers for now until I save a bit more money and decide what components to get. I will probably go with Boston Pros; I had those in my Porsche and liked them. I am also going with Alpine PDX amps because I had two of those in my Porsche and I like the fact they are small, stackable and sound nice. Along with a couple hundred dollars worth of Dynamat, that should be it. Anyway…

My questions are: Will I need to upgrade my charging system such as battery and or alternator? I will probably need a cap regardless, what size and brand, Stinger 1 farad? Will the Alpine 1000 watt be enough to power both 10w7s? According to JL’s site, that should be just right, 500w per sub.

I have competed in DB Dragracing before and know what 145db sounds like. I hit that in my Saturn with 2 12w6s. What db level can I expect from the 2 10w7s with a properly tuned box and the Alpine 1.1000? I know this is a very hard question to answer so I am just looking for a ballpark. Can I expect low 150s or high 140s?

Ok, I think that’s all the questions I can think of now so thank you in advance and I will keep you posted in the coming weeks. I go and check out the subs this weekend.
