audio set-up for beginners [continued]

[desmosedici]

if ayaw mo ng rear speakers, pwede mo gamitin yung 2 channel pa for an underseat sub. May shallow 8inch subs na kasya underseat, may box na yun. Ganun gamit ko sa navara, maybe sa carnival kasya rin and pwede mo naman isecure ng ayos yun sa ilalim, at pwede mo pa idownfire, tulad ulit ng akin haha. Im using pioneer premier 8" shallow sub, never tried an active underseat sub so hindi ko masabi if mas ok yung tulad ng akin porket may box sya na mas malaki.

Or why dont u try yung custom box talaga for 10inch subs? Yung hindi pinapatong lang, yung nakakabit na talaga sa car mo yung box haha.

Thanks for pointing out the existence of these shallow passive subs. Prior that I thought all under seat subs were active. Will consider this especially since ang box requirement niya is only 0.15 to .5 sqf.

Question lang po, ano advantage ng passive sub like the one you have in your Navarra to something like this:

Pioneer TSW-X12A Powered Subwoofer | Mickey's Autosound

Mas effective or madali ba ang tuning if one were using a passive sub?
