[QUOTE="LCP, post: 127027, member: 2424"] Yes, it is preferred to get a dedicated monoblock for sub... the MRP-F240 might not have enough juice to drive the type E sub cleanly at large volumes, if you are not careful, it may lead to premature death of the sub (running square wave, from an over-driven amp, into any speakers is always a no no). Here's my sub setup, still on my other car that is... Amp: Alpine MRP-M350 (200W RMS 4ohm, 350W RMS 2ohm) Sub: Infinity Kappa Perfect 10.1D, dual coils wired in parallel for 2ohm, 350W recommended input power, 1400W burst. Sub case: 0.6cu.ft. sealed Both the above were bought in the US of A, amp was US$150, sub US$120. Sub case and installation done here locally, RM350. LCP [/QUOTE]
