Default Building first sq system. Advice.

I am in the process of sound deadening my Jeep cherokee. I have double layered the roof with b quiet and put a single layer everywhere else including the floor. So far I have a jl W6 10 in a sealed box and am planning on buying a set of Hertz 165 XLs for the front and running them off a Jl 300/2 amp. I will be running my sub of a Jl 500/1. and getting the Dex P99rs for my deck. I have been trying to do my homework and have been doing a lot of reading and just looking for a little advice or suggestions before I purchase everything.
Thanks for your help, Justin

Sounds like a good setup. May want to to look at CCF for the trim panels, and some MLV for the floor, but your equipment choice seems to be a great platform!

Thanks for the advice! I actually put a few heavy coats of Herculiner on the floor over the B-quiet on my Jeep and took out the carpet. From what I have read It should help deaden the sound quite a bit to.

If you are going to use the P99rs, use enough amp channels to match the number of speakers. For instance you have 5 speakers, so you would get 5 channels of amplification; one for the sub, 2 for the tweets, 2 for the mids.

So is that like running them active then? I would gain a lot of tunability out of this correct?

Also how much Power would they handle if i did so? I was looking at the JL HD900/5 or the Zed Leviathan to Power it and bridging channels 5 and 6 for my sub. Any opinions on these? from what I'v read they are both pretty good amps but would 150 watts per channel blow my speakers?

Yes that would considered active. Yes, much more tune-abliity.

Power is relative to frequency and Speaker mechanical limits.

In either case, the Power is dynamic and not continuous. So, the woofer would rarely see the full power in either case. What the 200 watts would allow is much more dynamic headroom for the full bandwidth of the driver. 80 hz bursts will be fine as you're still not even close to Xmech. Now, clip the amp, and throw an 80 hz sine wave on the thing, and the driver will cook really quick. But, being smart with the gains, and crossover point and you'll be fine.

Also those graphs are essentially, IB, with a Qtc of .5. Driver excursion is barely limited by air pressure. Create a well sealed off enclosure, and you'll have even better excursion potential.
I think both amps would be fine. The Leviathan is more versatile. Just compare the specs for the 2 and read reviews.

Thank you for all your help! I think I have much more reading to do. I think I will run them passive for now and maybe get a different HU.
