i have to 2x 10's at the moment, entry level eclipse SVC 200rms per, reveiving 250rms per, in a total of 1.9cuft and they sound fantastic, consistant 137dbs! upgradign to 2 Soundstream 10's(750rms) they will be fiberglass in the corners of the boot to retain the centre boot space.

fiberglass enclosures are your friend!

Please don't quote dbs unless it was done proffesionally...

i have run (not all at the same time) 1 x 10", 1 x 12", 2 x 10", 2 x 12", and to be honest there isn't a lot in it. a single 12 will sound better than a single 10" but once you go double they sound similar. i ran 2 10's in a festiva and if you cranked it up you could make the engine stall. it would make you feel sick after about 1 song

Im assuming standard battery and tiny wires with horrible ground points in a plastic car? :(

for the record i have run (not all at the same time):

1x10 (1 setup)

1x12 (3 dif setups)

2x12 (5 dif setups)

3x12 (1 setup)

1x15 (2 dif setups)

2x15 (1 setup)

I have a CDT 12" sub in the boot tucked into the drivers side corner, very small im pretty sure my ICE guy said it was 1.2 cubic foot enclosure. Not 100% sure, but i believe this is about the smallest enclosure you can put this sub into. Awesome sound quality without too much big boomy bass, im pretty sure it would be a lot louder with a bigger enclosure though. BTW it runs of a single DD 1000W Amp, enough kick for 2 of these subs.

Just look for a sub that does what you want, check the specs you would be surprised the kind of enclosures that some subs require.

from my experience it depends what speakers you have, in order to match for the bass, my 10" alpine x sound great at low volume but drops off very quickly as its increased trying to keep up with the 4 amped 6" speakers

im currently running 2 12" boston G2's, they are exelent take up a bit of room but i swap back to my 10" for trips out of town for the weekend

Good point about the speakers. I have CDT 6.5 Splits up front and Alpine Type R Coaxials in the back running off a Lanzar Amp. I find as long as you have the ability to adjust the volume on your sub/s then turning the volume down is not so much an issue. I am frequently reaching for the sub control as i listen to a range of different music styles. Im lucky my headunit can control the bass, as well as having the volume control for my sub up front. I imagine sound deading your boot would do a lot to keep the bass "in cabin", (warning off topic) which is something i will doing soon, as my next upgrade is a set of Hertz Mille MLK2 up front, move my CDTs to the parcel shelf and run the 4 speakers off a 4 Channel Amp, looking at the Audison Vrx 4.300. Also wouldnt a 12in sub be able to still move more air at a lower volume?

Basically the Short answer is this...........

Go for what ever sounds best to you. No-one can tell YOU what sounds good to YOU.

If you like the Punch from 2 10in Subs then go for that, Or if you think that 12's sound sweeter then that's what you want.

Personally I have always prefered the Low Rumble from a 15in, but that may have to go by the wayside when I finally get my 34 (Space may not allow it).

The general rule of thumb is the smaller the speaker, the quicker it can react to signals.

The Choice also depends on the type of music you will listen to.

Hopefully this may have given you something to mull over.

If all else fails, Seek help from a Professional.

    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
    • Does the scanner do all the CUs in the car, or only the ECU?
    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
