The woofer in my RX is blown and I'm looking for a replacement. It's 4" component speaker with dual 2-ohm coils. About 2.25" deep.

I understand the option of fitting an aftermarket woofer but would like to replace this irrespective of additional bass.

Thanks!

Wow, I had no idea that thing was a 4 inch driver. I figured it was 5 or 6 inches at least.. Well, I guess you could find something here;

What was the location of this speaker? Front door, rear door? It's not the subwoofer, is it (they are usually the dual voice coil components)?

It is the sub--it's fitted inside a plastic enclosure under the passenger seat.

I've determined that it's not worth replacing; rather, it makes more sense to install an aftermarket amp and subwoofer in the trunk (or maybe a flat panel-style sub under the passenger seat), and disconnect this one altogether.

Wow, never realized our "subwoofer" was a 4 incher!

Does anyone replace this 4" subwoofer located under the passenger seat?

Mine never did much, It made sound, but I would have to put my ear nearby to hear it, rather than be obvious like a subwoofer should be when the sound is up.

I recently took it out, - and when I inspect the box, there is a lot of molded plastic, screws, and engineering that went into producing this subwoofer. It seems like it a bad design, that never did much for the effort involved. Is there a way to get it work? The discussion seems to mostly be, that its not worth bothering with.

I am not an audiophile, but instead of ear, feel the sound with hand for a sub. It is all in the enclosure porting/ducting/or_lack_thereof.

To answer your question .. I have not removed front passenger seat. My knowledge is limited to the impact of the sub under the seat ,,,,, you can't raise/lower passenger seat.

Just wondering; how hard was it to take out if it was "buried" under the right front passenger seat? I only want to know in case i ever need to access mine for some reason. also; if one decides to take the old one out; and replace it can you put a bigger aftermarket sub in the same mounting location?

Its held in by four bolts, two on readily accessible tabs, front and back





I had to unbolt the seats as well, which are also held in by four bolts, two up front and two behind. - have to remove the plastic trim from the seat rails to get to them.

There doesn't appear to be enough space to put a different style woofer under the seat. Reading the forum, it seems like the location of choice is in the rear location for the spare tire. It also requires a power amp. I don't want to go that far.

As a reference, the factory sub-woofer is 2 Ohms.

cool! thanks for the pic! hopefully i will never have to remove it but glad I know now that it only took a short time to get it out.
