I'm a total newb at this so please correct me if something is wrong. I've been thinking of getting a budget sub since my stock sub blew out... I pretty much decided on: 1- Alpine Type R 12" 1242D 1- Alpine MRP-M500 In a ported box. From what I've seen from searches, the type R is a decent sub for the money. I don't want to set off alarms or anything, just enough punch and deeper bass. Does this sound good? Should cost around 250 for sub+amp and maybe another 100 for wires+box. Also if everything sounds good, can someone recommend me a cheap ported box?
