Ok so I just found out that my amp is blown. I need to find a replacement but my current amp is very expensive to replace, so I was looking to get a cheaper amp. My current amp is a alpine pdx 1.1000 http://onlinecarstereo.com/CarAudio/p_17271_Alpine_PDX-11000.aspx I was looking at http://onlinecarstereo.com/CarAudio/p_19157_SoundStorm_STA120.aspx as a replacement, do you think it will work? My subs are 2 JL Audio 10 W6v2. http://www.onlinecarstereo.com/CarAudio/p_12513_JL_Audio_10W6v2.aspx It looks like everything is the same, 1000 watts at 4 ohms, the only thing different it looks like to me are the frequency ranges but does that matter? Also, what's the difference between a digital amp and a power amp.
