New speakers into 2004 Frontier truck

Three years ago I installed 6.5 inch speakers in the similar 1998 Frontier regular cab my daughter drives, just had to cut off a plastic nub in the mounting ring (or could've drilled a corresponding hole in the speaker frame) and had to solder the new speaker terminals because the Frontier ones used a proprietary connector.

I needed to replace the door speakers in my recently-acquired 2004 Frontier King Cab. Internet searching and posting on two Frontier forums for a few weeks led me to find that nobody actually KNEW what size speakers they would take, even sites like Crutchfield. So, knowing that the 1998 used 6.5 inch speakers, I bought a set off those and also bought a pair of 5.25 inch speakers, since that truck is 100 miles away.

Anyway, after taking the door panels off, found out that Nissan apparently thought too many were taking away their replacement speaker business and had changed to a one-piece speaker/mount using three mounting screws, used a speaker with the positive and negatives opposite to every other speaker I have ever seen, and still used a proprietary connector.






Anyway, the 6.5 inch speakers would fit and not hit the window when down (Dual DS Series #DS652) if I drilled four holes four mounting with sheet-metal screws supplied with the speakers. I also stripped the speaker wires a little (without cutting) and spliced in the wires supplied. Then I pushed the wire harness to the inside part of the door, and connected everything up.

Thanks a bunch, Nissan !!! When I had joked on the Frontier board that by buying both 6.5 and 5.25 inch speaker sets in advance, I was assuring that Nissan would have some "specialty" ones, and someone said that Toyota does similar.

Toyota and lexus and a few others do the same thing. I built spacers out of mdf when I replaced the speakers in the doors of my lexus. The magnets were hitting the windows but they were $300 focal component speakers

BASTARDS !!!!!

It's more about speed of installation on the assembly line. And fitting a certain space, they have no concern about aftermarket. I work in automotive, have my whole adult life. Speed equals cheap..

Pioneer makes an oversize 6 1/2 speaker almost a 7in (btw remeber the metric system Japanese car, American style speaker made from Japanese company) anyhow works great in newer Chevy fullsize, some Dodge and others like yours.

I think that most car parts are made on foreign soil but assembled in the States, Mexico too. A lot of metric being used maybe?

The people at Crutchfield are a joke they just read what the sheet tells them, they may have one guy who has 12 volt experience good luck getting him.

Scosche.com carries fact style speaker connectors so you do not have to cut the wires.

I am waiting for an auto manufacture to bring back the 4x10.

Looks like the same bolt pattern as the blower motor for the heater/ac in my B.

I learned years ago NOT to cut wires, just to strip back the insulation and solder new pigtails on, which also leaves future options. I do similar when I install a stereo head unit.

I believe Crutchfield and others do include speaker adapter plugs/sockets so one could just plug in.

The 6.5 fine, just didn't line up with any of the existing door frame holes (there WERE four pre-drilled holes for some sheet metal screws, which didn't line up, and thus just remained unused).

If a guy didn't need heat you could turn the fan housing into a subwoofer.
