I currently have 1 12" Type R hooked up to a pdx 1.1000 in a 1ft2 sealed box. I of course turn down the amp a little.

This system is for my boat and do to space limitations the speaker box must go in the engine compartment. When this setup is in my 96 accord the sub is loud. Unfortunatly the engine compartment has sound deadoning material and reduces the volume of the subthat I hear on the boat. So I am looking to get more volume.

I am looking at the FIQ 12 to swap out the Type R. I believe the PDX 1.1000 would be a great match and I plan oin using the4. Would the Q give me a big boost in volume? Would I still get the bumpage that my R gives me?

It doesn't seem like the sub is the problem here...it's where you have it placed.

I understand that the placement is not best. I have no other choice unless I have the sub box share the rear bench with my wife!

Do to this limitation I need more volume. Should the Q12 achieve this?

in that exact same enclosure with the same power...i dont really see you gaining too much "volume"

Post up some pictures of your boat. Perhaps we can offer a new mounting location.

Most people cut holes on the inside of the boat to mount the sub and then build a box behind it using the boat itself as part of the box.

never eevvvvvveeeeeeererrrrrrrrrrrrrr mount a sub directly into the side of your boat the fiberglass on a boat is designed to flex on an impact thats why its strong but the constant flexing in the form of vibration will soon leave you with a much bigger hole than intended

Well because the Type R is only rated for 500 watts I dial the amp back to only about 75% and only have my head unit sub setting on 75%. With the Q I should be able to run the amp and head unit at 100% settings.

This is where I think I will get the bass output to be louder. How much is the question. Would adding another 12" R be even louder? I want the Q because i'm think I can get somewhat the output of 2 R's from 1 woofer.

I can get an R on ebay for $120 and a box for $30. The Q will run $300 so will $150 more get me better results.

^^^^^ put up some pictures before you drop 300 on a new sub. The engine compartment is designed to be as quiet as possible, which is the exact opposite of what you want with your sub. Spending that money on a creative way to mount the woofer outside of the engine compartment will probably yield better results than adding a woofer or upgrading it

I would love to post pics....How?

Swapping out to a Q won't help. A new box or 2nd driver will do much more.

What do you currently have the R in for a box?

I don't have a larger pic of the engine compartment, but the sub is to the right of the engine. As you can see there is sound absorbing material. I'm think I might try to sqeeze the box in under the passenger gloe box. Besides that there is no room. The space under the rear bench is worthless.

Any sugestiions. I think that placement is key here not more bumpage.

no pic mann....

Not the outside of the boat, you tard.
