I have a 90 chevy single cab 2500
pair of jbl gti 10's old school single 4 coils - no idea on rms of them
currently on a old rf 200a1 so each sub is getting bout 120w atm.
box is down fire - 3" between the subs and the cab floor - center consil box
round pvc tube ports - I screwed up thinking I could use three 1.6" id tubes at 8" long each to achieve 32.5 or 33 hz tuning. yes I hit the tuning - but choked off the pair of 10s low bass hits good and hard. anything in the upper bass range plays realley soft and un satisfying in this config.
pix during the construction:
pix when I got it done - or what I thought was done until I realized I screwed up
then I was told I needed to rip out the trio of small ports and use a 4" pvc pipe - tried to fit it behind the driver seat coming out of the box - but driver seat is too far rear wards for that to happen.
so this happened - what an ugly mess of fail on my part atm.
hopefully I can do a little bondo work on the external port and smooth it in some what and paint it black like the rest of everything is. - all black paint is truck bed liner from rustoleum $43 a gallon at walmart
good part is it sounds WAY better than before
but I still am keeping the three existing 1.6" ports in the box.
when I sealed them up and played some songs - it did not sound as loud / good as when I left all the ports un covered. strange - as I thought id need to get those out.
anyhow - im a bit frustrated at the entire sub stage of this build - and my plan is to hook those subs up to my hifonics bx1605 @ 2 ohms should power the subs with anywhere from 850w to 1050w and will probly end up smoking them... wich will be sorta satisfying after all the bs this current build has put me thru.
on to the next one :
in this / my aplication so far - downfire box has not been good to me
so I drafted up this : a box for a single 10" or 12" sub same idea - center consil box
but with a standard slot port - and sub facing back cab wall up at an angle.
hoping for 1.75 to 2.0 cubes net for the sub - ported @ 35 hz
but since ive had such a hard time with this build so far - before I end up making any more boxes for this dam truck - id like you guys to give me some imput on a box style that I can use to the fullest potential in the single cab truck....
so please post any insight to the new box build please !
this is the beast btw.
