subwoofer install -- cubby install vs. cargo tray install?

hi y'all,

i've been lurking this site for a long time but this is my first post.

i want to add some bass to my aftermarket deck via subwoofer, without sacrificing cargo space

perusing these threads, i see two options:

1. custom enclosure on a 10" sub in the driver-side cubby with the amp in the cargo tray. questions:
   1. i can't find any of these on sale online for the gen ii prius. anyone know where i can buy one?
   2. if I need to get it custom-made at a local shop
      1. should i be using the extra space below the cubby area for the enclosure as well (this is the space that holds the battery on the passenger side cubby).
      2. how much should i expect to pay?
2. low-profile sub & amp in the cargo tray, leaving *in* the spare tire. questions:
   1. with the carpeted lid covering the speaker, how will the bass sound? (i don't want to cut a hole in the cover and have the speaker exposed). i see a user a few years ago tried this and reported good bass but he was using an add-on plastic weather cover vs the stock carpeted cover which i suspect may be more muffling.
   2. the slim powered sub from BOSS that was well-loved here on priuschat for this purpose a few years ago is not an option as the amazon reviewers say that they fry after a short amount of use. Does anyone have any recommendations for or against any of the following (assuming they fit, i haven't done my measurements)?
      1. Amazon.com: Pioneer TS-SWX310 12-Inch Shallow Series Preloaded Enclosure: Car Electronics
      2. Amazon.com: Kicker 10tcvt84 Tcvt8 Single Comp. Vt 8 Sub Thin: Car Electronics
      3. Amazon.com: Kicker Comp 07TCVT124 Thin-Prof Seal Box 4-Ohm Subwoofer: Electronics
      4. Amazon.com: Power Acoustik THIN-10BX Thin 10-Inch Wooferbox and Speaker: Car Electronics
      5. Amazon.com: Soundstream STEALTH13BX Shallow Depth Loaded Enclosure: Electronics

Any questions you can answer would be super appreciated! gotta get some bass into these tunes!

ps. for my deck, i'm using the brand new touch-screen double-din totally awesome sony xav-601bt (has android integration coming soon via mirrorlink, and runs on android itself, thus will probably get rooted by the hacker community which would rock)

 

thanks don... i understand the principle, but in practice, i guess i'm needing reassurance -- you weren't able to test it with the lid closed at all, without having cut a hole through?

 

ahh thanks. that's great to hear!!

 

how much "breathing room" would you think is required? would a single inch be pushing it?

 

if i'm reading you right, your suitcase could go right on top of the speaker, as long as there is no vacuum? so a full inch clearance then would be more than enough?

 

flareak, after you got rid of the rattling -- are you happy with the bass you're getting through the cover? do you have clearance space between the top of the speaker and the bottom of the cover?

 

cool, thanks... i appreciate your honesty.

currently i have my old sub in the back, and given your response, it looks like i'm just gonna leave it in there and get some quick detaches for the times i do need the space. i love the bass i'm getting from it. i spent a while experimenting with the levels. it's quite boom. (modestly, speaking)

1 further q: i have the sub w/amp, with a good new sony deck going directly to the factory speakers (non-jbl). i was surprised by how very much better the factory speakers sounded with the deck upgrade. at this point, how much improvement in sound to expect with a speaker upgrade?

got a link to your polks by chance, flareak?

peace
