[QUOTE="SYLrules, post: 4092177, member: 586670"] hi. i havent worked with any car audio for a while so im a bit rusty on this subject. i got my current setup almost 3 years ago and havent changed a thing since. its two 12" MA XL's wired in parallel with i think an MA HK1397 running 2 x 700w RMS @ 1 ohm. the amp is a class A/B and im wondering if id be better off with a class D amp? sometimes the amp shuts off and goes into protection mode when it hasnt been running for very long. it all depends on what song im listening to. i guess certain frequencies dont gel well with the amp? i dont listen to rap, only rock and metal, and some nine inch nails (thats usually what shuts off my amp). would the size of the box have any effect on how hard the amp works at certian frequencies? i need a smaller box anyway, this one would be great for rap (1.25 cu/ft per sub) but the ideal freq. is just a little too low for what i need it to be. thanks for the help in advance.
