okay so here is what im working with. 2000 mustang coupe, equipment, rockford T500-2. i know the amp is large for a 500 watt sub but i have it and ii looks damn good in a black car. so what i am trying to decide is what sub will be happier in the set up. i want to run a single 12 as to save weight. im looking into either a rockford T1 i know they are rated at 600 on last years model. an Fi SSD rated at 800 so it would be a little under powered. or an alpine type R. planned on using a ported box. i listen to all types of music and i love good sound and hard hitting bass.
