I plan on [temporarily] running an off the shelf ported box that's ~1.65 cu. ft, and powering it with an Alpine MRP-M500 amplifier.

Hopefully this will be good enough to replace the BOSE sub

 

Yeah I don't plan on pushing it that close at all.

It's a lot higher sensitivity than other subs I was looking at, such as the Alpine Type-R. So I shouldn't need that much power to get the kick I'm looking for.

Thanks.

 

awesome subs, i had those when i was younger......just simply will not blow!

 

Yes they will ...

That sub brings back memories...my very first one.

 

Thanks guys

Me and some friends installed it on Friday. I haven't tuned the amp fully yet, but it pounds! Sounds great too.

Hopefully I can get a deck soon. I am currently running a line out converter, I'll be buying something with 4v preouts.

 

An 8 ohm car audio sub?
