I want to place two 8" inch subs in a sealed forward facing box. I only want the box to take up about half of the space under the seat because I want to keep room for storage. I plan on building the box myself.

I was thinking about going with the Alpine 8" Type R subs. Mounting depth is only 4.5 inches and only requires .3 cuft per sub so they should work for a box this small. I have heard great things about these and I know Alpine has quality equipment. Picture for reference:



So, I personally think these would work well for what I want to do. It has been a while since I have done any work with car audio, so I want to know what other people think of these. Also, I would have to decided between 2 ohm and 4 ohm. Which one would be better for this and why?

Then, it comes to pairing an amp to work with these subs. Opinions?


And finally, a more general question. Has anyone mounted an amp behind the rear seat. It seems like there is plenty of space to fit a moderately sized amp. But is there enough ventilation behind the seat to keep the amp from overheating?

I know this is a long post but I want to get all the details worked out before I start purchasing the equipment I need. I appreciated the responses.
