I have a 99 f150 xlt red and tan extended cab truck and I recently purchased a Kenwood KDC-X396 Pandora Internet Radio CD Receiver and a 2 pairs of Rockford Fosgate Prime R1682 6x8-Inch Full Range coaxial Speakers and installed them they sound good but not great lacking the deep bass I listen to rock a lot and I want more bass but don't need a lot of power just some thump for classic rock what would u suggest I get maybe and 8 inch under the seat with a small amp ????


thanks for the tips on the heater core, speedometer solding point and gear shift indictor bracket I used them all ......great advice.

 

do a 10 under the rear seat in a sealed box and it should give you the bass you want

 

Update !!!!!!!!! buddy gave me 2 alpine sws 10s in a huge box ...........no way I can fit those under my seat............. then I was talking with my brother about it and he gave me a Rockford Fosgate punch rfp 3410 10 inch sub.
the mounting depth is only 5 1/2 inches I have 7 under my seat now in figuring out how to make a box for it and I found this web site http://www.the12volt.com/caraudio/boxcalcs.asp#rec it does the math for ya ............ man I aint no carpenter has anybody else attempted this..??????????????

 

If you don't mind the pre-built boxes. You can pick one up from ebay for 1 or 2 10's.

 

working with a slim budget going to make it myself.

 

7" isn't enough for a sub with 5.5" mounting depth. If you go with birch and make the box 5/8" thick that means you have a total wood thickness of 1.25", plus you need at least a half inch between the bottom of the sub and the box for it to vent, plus at least 1.25" between the face of the sub and the carpet or the bottom of the seat depending which way you place it.

 

back to the drawing board, man I don't want to get some those crappy low profile compact subs I hear they have a lot of problems with them maybe ill raise up the seat
I have fab shop where I work .make some spacers or something. I have a amp and 3 subs and nowhere to put them ................... just going to go with 1 10 inch rockford for now. may be ill cut a huge hole in floorboard lol.

 

Go with the alpine type r shallow. It was so good, it outperformed the normal type r and they had to go back and redesign it. I have one, its awesome for a single shallow 12 at 3.5" deep.

 

Kinda wish I had gone with a shallow under my rear seat. I have a JL 10w1v2 up firing. Removed the handle that lowers the seat, but it still hits the ring around the subwoofer.

 

By the time you buy the MDF needed, the screws or nails, the sealant to seal the box, and your time in building the box. You have spent more then what this one costs. http://www.ebay.com/itm/CUSTOM-FORD-...9ff546&vxp=mtr

Granted I know the feeling you get making something yourself. However I've started looking more at money spent. So unless your doing a crazy one off custom box, buying a pre-build normally ends up being cheaper.

 

Depending on your artistic ability this could be done. This is a supercrew and eveyone and there mom said it couldn't be done...guess they were wrong. These are 12's which pushed the envelope even further.

went to wally world and bought this



Scosche Full Range Speaker System with Two 6.5" Woofers

they were 29.99 lol guess what they don't fit under my bench seat took them back guess ill be building a box for my 10 punch somehow some way
got a free amp powerbass asa3002 amp no workey ......maybe I can fix it.??
any need some alpine rs 10s ins a box selling real cheap.i got them for free
along with the broken amp.

 

Just sell all the stuff you've bought, those free speakers, throw out that worthless broken amp and go buy a shallow mount sub.

Or buy a seat lift so you can build a proper box for one of the many subs you have.

 

^ This guy.


Hertz Dieci 250.5. That is all.

 

ok going to go with a a couple of alpine 6x9s under the seat instead of the sub.
but that brings up a few questions that aren't covered in the manual.
I have 3 sets of pre-outs front rear and sub if I use the rear pre-out outs will that effect the hard wired rears and fronts ie no sound ?????? or just use the sub pre-out and cancel all the filtering I think the deck can do that.

here is the link to the speakers im looking at .http://www.bestcovery.com/alpine-spr...axial-speakers
this is my deck Kenwood KDC-X396

so I can run 7 sets of speakers???
