They are far from going in the stock location.
And would need bigger and better amp anyway.
Have seen pics of amps mounted behind carpet beside tailight for plenty of room and consealed.
With our amp if you get the right channels bridge it to mono and would increase power for the single voicecoil sub. But I would reccomend a better amp. I have been a fan of audiobahn since the mid 90's.
And getting a frequency response at 30 hz on a 6.5" is impressive and would have good excursion for bass.
20-30hz needs ALOT of excursion but gives the feel of bass.
