hey guys, i need help on deciding which subs should i get better for SPL...I'll be running them with a monoblock soundstream picasso PCX1500D 3000w 1500wRMS @1ohm these are the options i got: 2x 12" Pioneer TS-W308D4 12" Subwoofers DVC # 2" Dual 4 ohms Champion Series Subwoofer # Power Handling: * Peak: 1400 watts per sub * RMS: 400 watts per sub # Impedance: Dual 4 ohms # Injection molded polypropylene (IMPP) cone woofer # Wide triple layer radial sound # Single-sided spring compression terminals # Dual voice coil # Dual mass magnet with magnet cover # Frequency response: 20-180 Hz # Sensitivity: 91 dB # Top Mount Depth: 6" OR 2x 12"ALPINE SWR-1223D 12" Type-R SUBS 2 Ohm DVC * 12" Dual 2 ohm Type R Subwoofers (1 pair) * Power Handling (pair): o Peak: 3600 watts o RMS: 600-1200 watts * Kevlar reinforced pulp cone woofer * 2-Piece Structural Parabolic diaphragm design * Injection molded Santoprene rubber surround * Alpine exclusive High Amplitude Multi-Roll (H.A.M.R) surround for impressive excursion and clean, accurate bass * FEA Optimized progressive NOMEX spider * Radial vented VC head sink * Concealed mount gasket system * Reinforced layer spider integration tinsel leads * Oversized 2-1/2" Voice coil * 4-Layer dual voice coil design * Voice coil made from 180°C high temperature wire on spiral cut aluminum former * Single-piece cast aluminum frame with Alpine Patent Pending Airflow Management System for efficient cooling * Airflow Management system controls the temperature of the voice coil by directing the air across the heatsink * One sided push terminals make installation and wiring fast and simple * Each terminal accepts up to 8 AWG wire for high power signal transfer * Concealed gasket mounting system hides the screw holes and makes for a clean install * Integrated grill technology allows for a seamless installation of a grill * US Patented Compound Radius Curve (CRC) design with integrated short sleeve configuration * CRC Machined motor structure creates a symmetrical magnetic field for less distortion and improves power handling * High-power, double-stacked strontium magnet structure * Newly redesigned for a 20% depth reduction * Frequency response: 24-200 Hz * Sensitivity: 83 dB and also with that amp, should i get 2ohm or 4ohms subs? im open if u guys have other recommendations for better subs with similar range of price. thanks andre
