I know they may not be exact but maybe they should be approximate.īut my single main question, why is this speaker clearly labeled 4 ohm when everyone says Volvo speakers are 8 ohm?įazool wrote:Apologies for the terse response - I am at lunch and only have a minute:
2003 volvo crossover how to#
See if I can figure out how to test for myself with a multimeter, what the ohm ratings of speakers are. Try to identify the frequency response of the OEM speaker Try to find out if having two crossovers messes things up (if the radio has this function built in alongside a speaker mounted crossover) Try to research if the Alpine 6.5 inch speakers are 4 ohm by themselves or only when wired with the tweeters In other words, maybe the Alpine 6.5s alone are not 4 ohm. Well if the box says the speakers are 4 ohm (doesn't clearly say each), maybe they are 4 ohms when wired as a pair. When I bought them I figured the 6.5s are basically what I am replacing and I just will not use the tweeters. The tweeters are designed to hang off of the 6.5s, not wired directly to the radio. From Crutchfield: "The Alpine SPS-610C features low-pass crossovers attached to each woofer's input terminal and high-pass crossovers in-line with the tweeters' speaker wires." My thinking here is that perhaps the HU is only putting out the frequencies that should be going to that speaker (internal crossover in the HU basically so the speaker doesn't need a crossover)ģ) The Alpines came in a set of two pairs, two 6.5 inch speakers and two tweeters. I don't think so and I hope not, I don't think it can be without destroying the speaker. Regardless of the type of music, at anything above really low volumes, it seems clear that there is not enough bass.ġ) I have replacement speakers with a wildly different frequency response rangeĢ) Maybe the crossover on the new speaker should be removed. And I don't mean I am trying to get everyone around me to hear that I am rockin' the Volvo. There is still bass coming from the back doors but those by themselves do not make enough bass to sound correct in the front seats. It sounds too tinny, almost like the bass is disconnected from the rest of the audio, just not right. So what the heck?! I thought Volvo speakers were 8 ohm? Not the pair I pulled from my front doors! So now I think ok, if I had 4 ohm speakers and installed 4 ohm speakers I'm golden right? Well something still doesn't seem quite right. But then I looked again at one of the front door speakers I pulled: I do want to figure out frequency response of the OEM speakers to help identify the correct aftermarket 8 ohm 6.5 inch speaker. I think I follow that reasoning so I started second guessing myself and began shopping for 8 ohm 6.5 inch speakers. I referred back to several forum posts and everything seems to indicate that Volvo used 8 ohm speakers wired in pairs so that the radio sees 4 ohms as most car head units, OEM or not, seem to expect. The fit is fine but now I'm not so sure that the sound is right. Anyway, found a nice pair of Alpine 6.5 inch component speakers SPS-610C, disassembled my OEM speakers / mounting standoffs and installed the new speakers. We did not discuss the intricacies of Volvo systems, just identified + and - on my OEM speaker. My door panels were supposed to be done and I wanted to get something (yes rushing things, 1st mistake) so I went to the local stereo shop (2nd mistake?), talked to a guy who has been there forever and who I do actually trust. I am working on door panels, noticed that one of the stock speakers was bad, went to the JY to get the only locally available replacement and it was worse than my bad speaker. My twist is that I have 4 ohm OEM Volvo speakers but I keep reading that Volvo uses 8 ohm speakers. I know some people are tired of speaker threads and I ended up posting a question in another thread but I didn't want to hijack it even though my Q was somewhat related.
