[QUOTE="alpb, post: 8497191, member: 669754"] Hi everybody, This is my first message and I need your urgent help. I have a blown Pioneer TS-WX610A active spare sub and it's in repair shop now for coil replacement. There is no info on internet about the specs of the two dual coil subwoofers included in this device. The repair shop insists that each coil of each sub should be 2 ohms. But when I look at the internal wiring, each coil (2 coils x 2 subs = 4 coils) is connected to the outputs of the PAL007C chip which has 4 outputs as 4 x 45 W / 4 ohms. So, What should be the impedance of each coil? 2 ohm or 4 ohm? The only data on TS-WX610A I've found is: Speaker specifications Size..................................................... ø 100(3-7/8" Dia.) mm × 2 High compliance, rolled edge Heat-resistant voice coil Strontium magnet: 280 g (10 oz) Amplifier Max. Power output.......................100 W × 2 (80 Hz, 30 % THD) DIN output power (DIN45324, 80 Hz, 2.0 ohm +B=14.4 V)... 70 W × 2 INPUT LEVEL (at Gain Max) (RCA).......................... 60 mV+60 mV/20 k (Speaker line)......................1.2 V+1.2 V/5 k Power source.................. DC 14.4V (10.8 V to 15.6 V allowable) Max. current consumption.....................................................14 A Grounding...........................................................Negative ground Your help is very appriciated.
