Hello, I wanted to ask the Specie’s here how to find the following subwoofer because I could get this just cheap and bring it to mention for installation in my car: Pioneer TS-W 305F Art.No.: 1856040050 Subwoofer with 800 watts maximum load capacity, 300 watts nominal load capacity, 30cm IMPP cone with networked aramid fiber reinforcement, 4-ohm swirling coil, frequency response 20 -2,000 Hz. Image – see appendix – I plan to build the whole as a ski bag solution – so if you use the back the You can see the sub behind the armrests! Besides, I’d like to know what you could recommend to me for a power amp?
