Anyone know of any reasonable under-seat subs or sub+amp designs.

I'm looking for a little bit extra deepness in the Supra.

.

.

I've currently got:

Head units: Pioneer AVHP6400 screen/tuner and a MEHP9200 slot-cd/minidisc.

Front: Infinity 655cs components.

6.5" Mids in the doors and matching tweeters in each corner of the dash.

Rear: Infinity 6502i 6.5" 2-ways.

In the rear side-pods.

Amps: 2 x Infinity RA7502 reference series.

(2x75wrms

@ 4Ohms) One amp for the front, one for the rear.

Each set is powered by its own amp

(ie 2 in total).

Quality is excellent; nice and crisp, strong mids and plenty loud enough.

.

.

just needs a tad more bottom end

(not interested in window shaking though!).

Any ideas? I know Pioneer used to do one.

.

back in the mists of time.

.

but seem to only do the

'tube' shaped ones now.

Whats on my stereo may help.

right now I have:

Smashing Pumpkins

- Rotten Apples
Chemical Brothers

- Push the Button
Bladerunner

- the motion picture soundtrack

Daft Punk

- Da Funk
Faithless

- Reverance
