If you go with that amp, the sub output from it should go to the doors.

Now you have to be careful though cause your head unit needs to have 6 rca outputs on it if you want to use a 5 channel amp or 4 channel & a separate sub amp. Of course you could also just use Y cables but it is noticeable difference when you do.

Any time I do a system my #1 priority is to keep things looking as stock as possible, especially in a convertible. Things are less likely to attract unwanted attention if something looks like factory. Those little active sub boxes from someone like Alpine are nice but unless you hind them well...they will attract danger. Almost no room under the seats so it's behind a seat (which isn't a good place anyway) or up in the foot well on these cars. Will have better sound there, but that means feet near a box/speaker.

The next best option is to get the Bose speaker tray and replace the 2 ohm subs in there with something else along with the 3.5" speakers on each side. Requires more power obviously, but this is one of the best setups to have in my opinion.

According to the installation manual for my AVIC-Z140BH https://www.pioneerelectronics.com/StaticFiles/Manuals/Car/AVIC-Z140BH_InstallationManual011612.pdf I have a left and right subwoofer output. It appears that I am in good shape for adding an amp to power two woofers.

I think I will install the wiring (two RCA cables and splice into the amp turn on wire) when I fix the vent foam issue next weekend. (I checked the video on accessing the dampers through the cowl, but it looks I would risk breaking a lot of potentially brittle plastic parts.). Then I will hint about the amplifier for a Father’s Day gift.
