Alpine CDE-122 Head Unit Polk DXi525 (5 1/4) x2 Polk DXi650 (6 1/2) x 2 Hifonics Brutus BRZ1200.1d Soundstream T6 12 x2 Streetwire Capacitor Song: Excision - Sleepless The new subs are so nice, they hit the lows louder, the higher notes not as much, but we also did a little tuning to the amp. I'm thinking about building a ported box. I'm getting either some Boston Acoustic tweeters or some off brand ones soon, and also carpeting the box, and getting better gauge speaker wire. Lastly, I'm doing the Big 3, how much of a difference can you tell after you've done the Big 3? The subs are around 300 off their RMS, they're getting somewhere around 550-600 Watts. I would love feedback, comments, and suggestions sorry about the bad recording lol Edit: New video!
