Alpine SPS610 C in a 2000 LX470

[Perroetaller]

Good day guys,

I have a 2000 LX470, and when into the "adventure" of replacing the front speakers. The ones I have are the Alpine SPS610 C This might be simple for a lot of you but it got complicated to me. I did remove both the tweeter and the bottom speaker, cut cables, replace speakers, put all back and it did sound like crap. Then did notice the box came with some "crossovers" and I had not install them. Took all apart again and did install the crossover from the OEM tweeter cable to the tweeter. Installed back and the right side sounds good, but left side sounds lower than the right. There is no "cracking" heard of on any side, but the passenger side sounds louder than the driver's side. Didn't mess around with the balance at all, but did play with it afterwards and to my ears it does sound louder in the right side.

How is the "crossover" that comes in the speaker box suppose to be installed? Does it go from the main speaker to the tweeter? Does it go like I did?

Thanks

The crossover that came with your speakers is a "passive" crossover. It is designed so that you send one speaker wire into it, and then it splits the highs out (for the tweeter) and the mids and lows to the bigger woofer.

Unfortunately, I don't know how the factory was filtering frequency to the speakers, so I can't tell you what the best way to go is. But I can tell you that what you've done so far isn't ideal given how your speakers are designed to work.

Thanks for your reply! Did remove panels and wired it from the speaker to the crossover to the tweeter. Does sound good now. Thanks again

Hum, just to clarify, it should be:

[Headunit/amp] ---single speaker wire (+/-) ---> [crossover] ---> two speaker wires (one to woofer and one to tweeter

The way you're describing it, it sounds like you have put the crossover after the speaker, and are just running the crossover only for the tweeter. That would be a bad way to run it since you either ran of the speaker to the crossover in series or parallel, both of which affect the impedance. It could also potentially damage your tweeter later if the impedance (measured in ohms) was dropped below what the speaker is meant to operate under.

Hope that helps more than it confuses. Again, too, keep in mind I haven't got into my stereo yet to know how the stock wiring is done...so I can't tell you the most optimal set up.

Good luck!
