So, I picked up Visonik's 1800 digital class X amp for cheap! It's not bad (hopefully comparable to JBL 1200!) I need new subs, cuz I have 3 10" Visonik's and they just aint hacking it! The ratings are as follows (RMS)= 1500 @ 1 ohm, 1200 @ 2 ohms and like 750 @ 4 ohms! I need subs! Space is not a matter, seeing as I drive a granny car with a HUGE trunk... Plus, I like tight bass, but SPL is a little more important. Also, I am a kid kinda on a budget, so no eclipse or **** like that! Thanks for the help!
