What's up I'm new to this forum but have been into car audio for a few years! Couple days ago i picked up 2 10" alpine type r's in a ported box, with a sundown saz-1000D amp, another alpine MRP-F300 amp, 2 more older cheap amps (MTX, pioneer), a kenwood touch-screen double din thats a few years old, and an older cheap 12" pioneer sub. Got it all together for $220 and everything works as it should! I think I got a great deal considering the 2 alpine subs + sundown amp would go for more than that alone where I live. Anybody used the sundown saz-1000d before? I know its an older amp but everything i found online speaks highly of it and the company.
