Tang-Band sub-woofer upgrade (Page 8/13)
fierosound AUG 02, 09:13 AM
Kenwood model would help. I went to their website and didn't see anything with 6 powered channels.

I saw some "6-channel" units with 4-channels powered by the HU and with pre-amp subwoofer outputs - which would require an amp. for the subwoofer(s).

What does the installation manual that came with the thing say? Most show the options of how you'd connect the unit.

The model is KDC-BT948HD

Thanks Fierosound, you are correct, there are only four powered channels.
I'll seek out a small amp for the sub...(was hoping to avoid running amp cables to the battery is all.)

Nice! I'll have to try this. I just wanty to improve my sound quality, not go BOOM BOOM! I'll have to get the replacement box from TFS but it looks like it doesn't come with the port tube. Guess I'll have to try and find one of those as well.

I wonder if any other 5 1/2 sub would work? Several came up with a quick google search.

edit, Amazon has them for $30.

i'm considering doing this upgrade but i'm a little confused on what part you cut off. did you do the cutting where the MDF is in the pic above or was the cut on the port tube that comes out the top. please set me enlighten me before i do something stupid.

thanks...

The end of port tube to shorten it. No modification to the box itself.

Fierosound,
Did you have a template for the MDF cutout? I searched but only found your 4x10 for the front speakers.
Thanks,
Bob

No template - the sub housings are too uneven.
Trace the thing on cardboard and cut it slightly smaller 'till it fits inside.

Use that for your MDF cut-out. Then make sure you center the speaker hole.
Drill pilot holes for all the screws, so you don't split the MDF.

Just a tad off topic (but definitely related), would someone be so kind as to post the dimensions of the factory subwoofer tube. Mine has always been missing from my '86 GT. I'd like to make a replacement one up from PVC tubing.

I found these dimensions posted in an old thread, but it's not very clear where the measurements were actually made from.

...the tube is 9 3/4" long by 2 1/4" tall and 1 1/2" in diameter.



I've included an image here that I found in an old thread. Keeping in mind where exactly I've indicated in the picture, could someone please tell me the measurement of both "A" and "B". Thanks.
