To give you some perspective. I have a 15" FI Q series sub, a 1000wrms Cadence amp, a custom 2.7cuft sealed box, and necessary hookups. In all I've spent about $800 or so. Did I mention I still need some RCAs and maybe an alternator? With your BTL I can see you spending $1000+ easily.

"You'll have to run a power cable from the trunk, and you'll have to reground." Not sure what you mean there. Are you saying I'd have to run another cable for my 2nd amp and reground a second time? But I do thank you for your reply. Anyone else's comments and thoughts are welcome. Bump

Logitech makes very nice 2.1 systems. Their subwoofers are more than enough for in house listening.

Before I get into too much detail I need to go over some information about the gear I'm working with. I currently have a 2.7cu ft box with a 15" sub in it that takes up most of my trunk. I have just enough space to fit my Cadence TXA-1000D amp in front of it. I also have a Pioneer GM-6300F 4ch amp. http://www.pioneerelectronics.com/PUSA/Pro...Series/GM-6300F So my sub and mono amp are going in the trunk, and I'm trying to determine placement of my amp and consequent amp install gear, both of which are variables that depend upon each other for optimal results. So I purchased this http://www.tsunamionline.com/product.php?id=532 a couple of months ago. (view page source to get the list of items uncluttered.) I've just recently gotten around to piecing together the rest of my sound system. My current obstacle right now is doing homework on installation and placement of grounding terminals, fuse holders, and distribution blocks in particular. Here's the diagram that Tsunami provides. http://www.sound-extremes.com/ebay/amp_kit...CAP/Diagram.jpg My initial instincts, after consulting with my dad, was to put my amps in the back and wire everything from there. Meaning keeping my fuse holders and grounding blocks as close to my amps as possible, and running a length of power wire from my engine to the trunk. Though one thing my dad suggested was stashing my 4ch amp under my passenger seat so as to keep speaker wire from being too lengthy. (Not sure if I should go this route or not.) More research lead me to Tsunami themselves and I got a chance to talk to one of their in house techs. He basically said that grounding wires should never be too far from their source, so I ought to think about placing most of my amp kit in the rear so as to keep everything tidy. One last bit of advice from him was to explore more alternatives so I don't screw the pooch and out myself $1000+. After all of that I want to know what you guys think. In your experiences with installing car stereo systems in front engine sedans how have you wired your setups? Do you prefer to keep grounding and distribution blocks close to your amps in your particular scenarios? Do you find that running one main power cable, (in my case), to the rear of you car is acceptable or even optimal? Do you see anything out of place in my current setup? (Pending that I've given you enough info) And finally, what would you guys do different given that I want to keep with the diagram and stick my grounding, distribution, and fuse block in the back? If there's anything else you guys need to know I'll try and get back to you ASAP. Thanks for you help in advance. I really appreciate it. Sincerely, Alex EDIT: TL;DR I know jack about this amp kit concerning placement. HALP

Thank you SEC. And Mr. Cabinetry, I've sent off the info for the quote. I hope to hear from you soon. Thanks for all the suggestions ya'll have provided, I really appreciate it.

Eh sorry, I misunderstood. At any rate nothing fancy about the box. Sealed with dark grey/black carpeting is all. Thanks for the sites patented17. Looks promising, I'll be putting in quotes for both parties. And JimJ, I'm in Virginia Beach.

Uh, I'm in Virginia. If you're trying to sell me a box PM me, we can talk shop that way.

So I got a 15" Fi Q for Christmas. Everything else that I need for my system I have as well. The only thing that is missing is a subwoofer box. Originally to save some money I was gonna build my own sealed enclosure. But after talking to some of my friends and family I decided to get a professionally made box. Here's the problem though, the only site that I've managed to find is, www.klausaudio.com. And while the site looks great and the options for customizing your box is superb, they're not taking orders right now. (Or responding to my frickin e-mails...) So I wonder if you guys knew any other respected custom box dealers/makers. P.S. Since I want a sealed enclosure I wanna hit the 2.6cu ft mark for the sub. This means I need a total of 2.79cu ft to counter the sub displacement. I know I'm not asking for plans on here, but if it helps my max dimensions for my trunk are as follows: 34in deep, 37in wide, and 16-17in high. I'm not sure if it ought to be forward or up firing. P.S.S. My car is a 2006 Mitsubishi Lancer OZ Rally.

Looked through the technical forum and couldn't find the topic on Hoffman's Law. At any rate thanks for the reply. I guess I should aim for the 2.6 limit after displacement then huh?

Hi everyone. I've been reading up on Fi Car Audio and in particular the Q series of subwoofers. I really can't wait to start getting my cash together for one of these bad boys. However I have a small knowledge base problem. I don't understand the exact effect of a larger box volume for a subwoofer. In particular I've read that the recommended box size for a sealed Q 15 is 2 - 2.6 cuft. Now, would the subwoofer get louder if the size was 2.6cuft vs 2cuft? There is more air to be moved in a 2.6 vs a 2 correct? But if this is true then would there be any other effects of having a larger box beside the obvious space consumption in the trunk? Bonus question: I listen to a lot of different types of music. Am I right in thinking that by having a Q 15 in a 2.6 sealed enclosure that I can expect it to hit hard when I want to throw on some rap or techno and that I can expect it to have form and clarity with rock or complex bass movements? Thank you in advance, and I appreciate your patience with these basic questions.
