Tko 12S4

I have a single 12 it knocks my rearview mirror off regularly. Not loud outside the car but bass is deep on inside.

Massive Audio for the win!

I have had a single sub of TKO 12S4 in my car for a year in a single ported box and it sounded great!
But then felt as though what one more can do, so I got one more from Sonic Electronix and placed it in a two 12-inch ported box with an amp that can handle the RMS and note it's not a record-breaker but for my daily driving on Door Dash lets them know their food in on the way!

Overall I would recommend this for just starting out hands down, and two thumbs up!

Note: Sonic Electronix is on the left.
