Yeah, that was my initial thought, that using the passenger seat would add a little distance for those low frequency waves to develop.

I've been all over google and search without finding anything dedicated to which seat will sound better to the driver.

My kid's car seat is on that side too so no feet kicking it.

It's a moot point if you have time alignment in your headunit.

You just measure the distance and dial in the delay required.

I don't have that on my HU.

It's a lot of work to get a little more bass.

Well, if you woofer was completely out of phase, you'd have no bass =)

But then you could just reverse terminal polarity to solve that... odds are you'll be somewhere in the middle.

Seeing as this thread was bumped thought I'd mention that the Kenwood I posted earlier in the thread completely died on me a while back. It was still powering on and everything but was producing no sound. I checked everything (tried different cables,different outputs from my HU) and no luck. Since I bought it from an amazon seller who wasn't a kenwood retailer I was out of luck in terms of warranty. Not sure if this is just a freak occurrence of if there is a known issue with them but I'm sub-less.

If it makes you feel any better, I had a Kenwood amp that died on me about 10 years ago, and I sent it in under warranty. They fixed it, and turned it around in about a month, and it worked great... for a couple months, then it died again.

Put it under the driver's seat. Bass is supposed to be nondirectional, but if you have it under the passenger seat you have more volume coming from your right.

With it right under you there is no perception of a discrepency from side to side.

Interesting point. Just when I had decided on the passenger seat. Thanks a lot!

I had a Clarion underseat sub under the passenger seat in my 2008 Legacy and was annoyed that it always seemed like more volume was coming from my right.

I would have changed it to the driver's side but the drivers side (only) was a power seat and the motor was in the way.

if you have the crossover set correctly, you shouldn't be able to determine left or right... but if you have the sub playing higher frequencies for more mid-bass fill, then yeah, you'll probably notice it.

I have my subs crossed in at about 90Hz.

For these under seat subs that's probably a bit too low. The published frequency response for the B-8PT is 40-200 Hz. If I set my crossover to 120 it seems to cut out most of the unwanted "noise" but at 90 it cuts out almost everything. I still haven't really found a sweet spot, so I'm constantly adjusting it depending on the music I'm listening to.

Sad but true. I was playing around with it yesterday and it drops off significantly around 55hz.

So I'm doing the install this week with the sub under the passenger seat and I have a question. This is my first attempt at anything like this, btw.

I'm going to put the power line through the driver's side grommet and down the sidewall under the door jam to the under seat but I'm wondering what the best way to go from that side across the car to the passenger seat.

Do I go under the carpet under the driver's seat, across the center console (inside) and then down under the passenger seat?

I think I'm pretty clear on the rest. (famous last words)

Yup, that's exactly how I did it. There are lots of spaces under the carpet to route the wire through.

Cool thanks. Still haven't decided whether to go from the HU to the sub down the center console or passenger door sill.

I ran my remote turn-on and RCA interconnects down the center, and power down the driver's side.

All done! I took my time and tried do everything as neatly and invisible as possible so it took me around 3 hours or so. Thanks for all the tips.

Today will be lots of setting tweaking but initial tests sound great. That's all the bass I need.

It's under the passenger seat and I'm thus far not noticing the sound coming from the right. Being able to feel it under my butt would have got on my nerves more.

My wife instantly comes down with a case of the giggles whenever we take my car anywhere.

Focal also makes an under-seat subwoofer. I was considering this until I just ended up buying a regular 10" subwoofer from them to go with the Audio Integrations sub box in the hatch.

Anyone still thinking about an under seat sub, check it out: http://www.focal.com/en/plug-play/27...050750135.html

Time to bump this up again! I am in the market for an under the seat sub. Any new products out there or do you guys still recommend the SO one? I like that if you buy it from Crutchfield you get the free wiring kit. Great price at around 150-160.

Probably going to post mine for sale soon, just have to figure out what the shipping is going to run so I can price it accordingly. I upgraded to a 12" in an Audio Integrations enclosure about a year ago.

I just installed a kicker hideaway under the driver seat in my '13 base wrx. I love it, though its a bit much for my old ears so I keep it turned down to a reasonable volume. (Extra points if you read the last two words in Milton's voice.)

I had an extra wiring harness from installing an oem sub in my wife's '10 FXT with nav.(they give you both harnesses with the sub)
