| I'm probably not as knowledgeable as you in the car audio field, and want to know more about this. I'm going to upgrade my speakers (in an older Volvo, not BMW) to a pair of Alpine 6x9s on the rear deck. I would rather not do any cutting, and was planning to simply use speaker boxes from Crutchfield. Is it really that much of a difference in audio quality? I'm going to be running those speakers, and Alpine 12" Type-R sub, off of an Audiobahn 600w 4-channel amp. Would you reccomend not using the speaker boxes? |
If you are using a subwoofer, you could get by with putting them in the boxes. Your 12" will do the bass part and your 6x9"s will do the midrange. They probably still wont perform as well as they could, BUT putting them in the same airspace as your sub may shorten the life of them, because your sub moves a whole lot more air than the 6x9"s ever could, and will beat them to death.
I know my 525i is really quiet going down the road and they do that on purpose, in blocking out unwanted low frequency road noise while you are traveling (thats why we all paid the higher price). On the down side of that, subs reproduce low frequencies that we want to listen to
On my car, I put my 2-11"ers in a bandpass box and used the factory "ski hole" for the vent and sealed the rest from the trunk. This way all the sound comes into the inside of the car and I retain the quiet ride, and the trunk doesnt rattle. Im not sure if your Volvo has an option like this, but it worked for me. If you are going to do a subwoofer, dont worry about fitting/buying 6x9"s, just get a GOOD pair of whatever your car takes, (i think most 80s early 90s volvos were 4", present day are 5.25???) and you will probably have a better performance than if you tried to squeeze the 6x9"s in the wrong enclosure.
| On a related note: I haven't yet bought my sub, and am deciding whether to buy a 12" in a sealed, no-name (or Q-logic, etc) box, or the same sub in the Alpine-designed enclosure (bandpass). I'm not asking about the difference between sealed and bandpass, but rather whether it would be good to go with something engineered by Alpine. Do you have any insights you could share? |
These companies do a lot of R&D to make their respective woofers work with their boxes but its not necessary. Any enclosure (as long as its' specs match what the manufacturer recommends) will work fine, the wood/plexiglass/fiberglass enclosures make VERY little difference, everything else remaining the same.
