Hey guys, well i just bought 2 10" JL Audio w/ a 100 RMS Rockford Fosgate amp. Is 100 rms a lot? It says 100 Rms w/ 4 ohms or somethin like that. Is this good? i bought all together 2 10" JL Audio w/ box and 100 RMS Amp for $200. Will the Amp be good enough for both Subs? Isn't RMS different from watt, just like Hp from whp?
