well, my pat did not come with the BA system.
and, after talking to another member, it would be close to 1k in parts to add it! lol...
so...had a mtx sledgehammer amp and 12" sub installed.
turned out great.
bridged for 200w.
blends with the factory system perfect.
amp- mtx sledgehammer amp #JH202
sub- mtx sledgehammer 12" sub #JH4512
all installed in the cargo area.
you can still flip the rear seat down, then lift the cargo cover to get to the spare.
not bad for $425 installed.
