Re: Different Size Subs?

Running the sub in the shelf will be wasting space and amps. They don't supply enough bass due to shelf flex.

Re: Different Size Subs?

put a decent sub in a well constructed box in the boot with an amp that over powers it and turn the amp back an single twelve will make more than enough sound to make your ears bleed with excitment

Re: Different Size Subs?

I used to run 2 8" subs in the parcel shelf and 2 top of the line kicker subs in a massive box in the boot. It works really well.

What you'll need is a 4 channel amp with enough power to run the big subs and it must have a low pass filter on both the front and rear channels.

Then wire the 8" subs on the front left+right channels of the amp (most 8" subs do not need a lot of power to run) and then wire the 2 big subs in paralell-bridged mode of the rear channels.

If your amp is anything like the kicker amp I used to run it will have a frequency adjustment. Set the 8" subs to higher pitched and the big subs to lower pitched. That way you will get buzzing mid bass from the 8's and earthshattering lows from the big subs.

I don't have the 8's anymore but I wish i did, they really did make the sound so much fuller, but if you only listen to dance music there is not a lot to be gained from them. The only way to make sound from a sub in the parcel shelf is to make a new one out of 18mm MDF. The stock parcel shelf is way to flimsy to install anything decent in.

Just like a Tsunami.

Re: Different Size Subs?

go with 2 12" subs or 2 10" subs boxed in boot facing out between rear seat amped and ported for a real defining sound

Re: Different Size Subs?

If you are going to run a mixed combo of subs, Play around with sub phase, as if they are out of phase, it will sound lifeless.
Personally, id recommend a boxed 10" facing the back of the car.

Having a free air sub on the parcel shelf will cause more rattles and will distort a lot quicker than any properly tuned boxed sub. You also will not get the same depth from a free air sub, most battle to play any lower than 80 - 100 hz, due to lack of loading.
