Default My front stage.

I havn't been on CARFORUM since 2007..

So my front right speaker distorts badly, even at low volume, and there is a lot of vibrating resonant noise down there.

No problem I thought, I will just replace them. I pull the door panel off to take measurements (because Crutchfield is wrong) and I see this:

Pretty weird. Its a very cheap mid-woofer with a 1.5" magnet. I can actually see through the thin paper film. It sits in a plastic case.

I purchased a set of components: Diamond Audio D363. Now the plastic casket will not fit, because the speaker opening triangles towards the top. So I had to cut a larger hole for the 6" woofers.

Furthermore, I am using the stock radia unit, because the heater and climate controls are built into it, so I am unable to replace it with a aftermarket unit; besides, I like the stock look.

I also learned that Hondas stock audio system has a poor high-pass filter for the tweeter (mounted in the dash). The cuttoff frequency is 12kHz; your average 6" woofer may have a response to 5-7kHz, so that means a LOT of information is being completely discarded (7kHz - 12kHz)! Also, there is no low-pass filter on the stock woofer that prevents high frequencies from being passed to it.

Just though I would share.

Thanks,

I'm still a little iffy about my tweeter location. Kind of wish I put them in the stock location.

Forgot to mention I also have a new 4-channel Alpine amplifier. Had to use speaker level inputs, but Alpine amps do a pretty good job with the high-level inputs.

I did have a 10" RE subwoofer in a small sealed box running off the two rear channels (bridged), but no matter what I did it just didn't sound right. I wanted the bass to blend in with the front speakers, but I guess with my variety of music every other song seemed compromised with my settings. So I took the sub out.

...if that made any since

If only I could get the sound my Paradigm speakers make in my living quarter.

Yeah, I took mine out too - since I mostly listen to heavy metal/alternative, the sub just muddied everything up. Such a shame, some songs sound so nice with it in. For a while I just had a toggle switch so I could switch the sub on and off while driving, but I got tired of doing that.

Any music can use some bass, but the car environment is so harsh. My home speakers have some bass, but they are placed in a excellent enclosure, not a car door..la

I will replace the rear 6x9's and run them off the Alpine's rear low-pass filter output. Hopefully that will add enough depth.

Anyone know of a good 6x9 woofer on a budget?

you can always add another set to the stock location

are your HVAC controls mounted TO the radio, or do they share the same bezel? (like)



Crutchfield has a kit atleast for mine that allows me to use an aftermarket radio and keep all my knobs etc for 40 bucks.

I didn't mean I wanted more highs.

There is no kit available for my car, being dual-zone climate. There is a kit available for the "regular" climate control Accord version, but even so, it is very cheap and apparently the buttons fall off.
