[can i]

If its a pa woofer, i might overpower the mid bass therefore u will have no low end, depends on the enclosure i guess.

[Slot Port double back?]

i had my 2 15's tuned to 26 for my hometheater/music. I got tired of replacing light bulbs in the ceiling fan from rattling the wire off.. But 26 was pretty good for all types of music in my ears. Therefore it gave you that nice kick drum on rock and nice LOWS on rap which i love. Therefore it cut off around 45 hertz in my room, therefore my front speakers handled it from there. Another words i dont think its to low i love it haha.

[speakers to amps]

they are focal kp 165 4 ohm

u could run them on 1 channel, it will be as a 2 ohm load on that channel.. if u use 2 of them haha lol

[need help picking subs]

2 DC xl's 1 amp per sub.. Size up to you.

[How can I stop the rearview mirror from vibrating so loudly?]

Take the system out, or turn it down so it dont vibrate lol.. Since you cant take it off.

[Sony House Receiver]

Shit! 1 Ohm? Thats pretty good. It must get hot as hell though. Thanks for the advice on getting a sub.

Nope doesnt get hot or anything, mines rated at 1 ohm, bro ran this reciever at .5 ohm all day for like a week never got hot or anything. I had another sony reciever ran it at 2 ohm, that thing got HOT!!! melted my subwoofer terminals off haha, got my money back and replaced it

[Kicker L7s and FI Subs]

Or just get a crescendo and run it @ .5 ohm will still be under warranty until .3 ohm for 3 years

[need help choosing a new sub]

I like the diamond audio idea i got 2 D3 15's they sound pretty good on 1200rms nice and clean

[Make Up My Mind For Me]

i would really like to own some dc subs but the closest dealer to me is in indiana and he wants 580 plus shipping per xl 15. thats a little out of my price range. what are some other options that you guys think are possible for me. ive heard nightshades are really good but i have never seen prices on them. if i do end up going with btls, what options should i get on them.

What store/dealer did you find in indiana, cause me and bro were looking for subs for his truck.

[Vizio TVs]

I love my vizio 32" 720p tv. Runs my ps3 and computer in hd perfect. To this day the picture looks just as good as my uncles 50" samsung plasma. It also even runs my games at 1080p and look flawless while doing it.

[Sony House Receiver]

I would say yes, because i run a sony reciever. It will handle my 2 15" diamond audio all day at 1 ohm Oh yea, make sure you get a sub because sony filters out the bass in the front speakers, atleast it does for mine.
