Audio System, A few last questions, before i finalize Options

[Legit94GT]

So I have big plans for my audio system for my car... I am going to run 2 10"s in the trunk in custom fiberglass housing, and add two 5"x7" into the hump in the back seat, add upgrade all speakers in the car.

This is the early stage of the build i dont know what i kind of anything i will be running, but i got hook ups at car toys at get crazy deals(like my 800+ alarm i got for 350 installed) So anything i add will be high end, keep that in mind. My girlfriend runs 1,000 watt amp off two tens and they sound great, since i have a smaller car i figure that running 1,000 watts plus a 8.2 sound system should be freaking awesome And yes she loves to throw it in my face that her stereo kills mine

Part 1. Subs in Fiberglass
I want to palce subs up by the hinges for my trunk, right above the wheel wells, i think i can fit some slim subs in there, or maybe evern full sized... If i mount them up there should i build a metal bracket to hold it in place then build the fiber enclosure around that? What are some of the Pro's and Con's of having subs in fiberglass enclosers? Does it hurt the sound quality? Could i break the subs out of the fiberglass, or crack it?

ok imagine that but surrounded with fiber glass to make it look like it belongs in the car:)



Part 2. 5x7 in the back.
I am planning on taking out the bottom half of the back seat and cut out the center part of the hump. the distance between the two lines that run down the middle of the hump are like 4.75" apart so i am planning on cutting all of that and then some to make room for the two speakers. This way i will keep the back seat looking and feeling mostly stock. I am planning on running plexy glass where there use to be soft padding and middle back seat, so that the speakers will mount onto that so you can see the speakers(and sit on them, the only downside).

So has anybody taken out the bottom of their back seat (i have coupe, not sure if that matters), if so is there so long process or is it straight forward?

kinda what i am thinking here



Part 3. Power
I have red alot of forums where people drop in these huge systems the cant power them off a their stock alt, i do not feel like going through all that trouble untill i have to (IE when it goes out, then i'll put in a nice one) So i was thinking i could just run a second battery to power my sound system. I could find alot of info on how that would get wired exactly... Would i have to wire my head and all my speakers, subs and amp to my second battery then have a kill switch for it? Then i would just run that untill that battery died? Where do most people put it, i was think under the passenger seat... or under the hood?

I am sort lost on how that all works, if someone could explain it to me just how running a two battery set up would work tht would be amazing, because i think that is the way i want to go for power.

Part 4. Amp
Generally speaking here, With all of the above mentioned speakers and subs would 1,000 watt amp and a good head unit be enough to power everything or should i plan on going much bigger??


Again sorry for the bad pictures and those are by no means what i will be buying for this, those were just quick googled images. Thanks in advance for the advice and suggestions
