- I have an '87 MR2 and have spent a -lot- of time (and money) on the
- stereo system. Depending on how much money you want to spend and how much
- of the car you are willing to cut up, I can offer several suggestions.
-
- 1. The cheapest and easiest option is to replace the cheesy 4"
- speakers Toyota puts in the dash with higher quality speakers. Crutchfield
- sells a set that are designed just to fit in Toyotas, made (I think) by
- JVC. THe only difference between these speakers and the "standard" 4"
- speakers is that they only have two mounting holes instead of four, so you
- can buy standard 4" speakers and modify them by cutting off the extra two
- holes if you like.
-
- 2. You're right, the little subwoofer under the seat is cute, but
- not much use. Unfortunately, there isn't much room for any other speakers in
- an MR2 without some compromising. If you are not very tall (if you are, what
- are you doing in a sardine can like an MR2 anyway? <grin>), you can -barely-
- fit a set of .5 cubic foot box speakers behind the seats. If you have t-tops,
- stow them in the front trunk (they will fit, I promise). I use Ultimate box
- speakers, which I am moderately pleased with. You can power them with an amp
- under the driver's seat once you remove the factory subwoofer.
-
- 3. If you're really brave and handy with a metal cutting jig saw, you
- can cut holes in the door panels for bigger speakers. It is possible to mount
- up to about a 6" speaker if you're careful, and make sure that the speakers
- you buy are shallow-mount types. If you have power windows, (I don't), I am
- told this is just not an option.
-
- 4. SAS makes a special bass enclosure called the Bazooka, which comes
- in various sizes. I have not tried them in my MR2, but based on what I have
- heard at car audio shows, this is the best way to go for bass in an MR2. The
- Ultimate speakers I use have 10" drivers, but the laws of physics limit the
- quality of the bass produced in a .5 cubic foot box, no matter what you do.
- Also, putting the driver right in the back of the seat may give you a big
- thrill whenever the bass kicks in, but it's not exactly high quality sound.
- Bazookas actually point into the back corners of the car and use the entire
- car as part of the "enclosure" for the bass, which yields deeper, flatter
- bass response.
-
- 5. Instead of using full range speakers in the dash, you could mount
- 4" midranges in the dash and put 1" tweeters in the tops of the doors. (Some
- cutting involved here, but no metal). If you buy high quality components, this
- would generate very clean mids and highs, which would complement the bass
- coming from behind the seats. Since bass frequencies are non-directional, it
- would sound as if all the sound was coming from in front of the car.
-
- 6. Since the interior of the car is so small, you may have problems
- with resonant frequencies. Using some kind of equalizer can really help, but
- the kind that only have 5-10 bands won't do you much good, since you end
- up cutting out good sound along with the resonant frequencies. I use and EQL
- by Audio Control Industrial, which was relatively low-cost, and is very clean.
-
- Let me know what you think and what you you end up doing. IMHO, the
- MR2 probably is one of the most challenging cars in which to get decent sound.
