[QUOTE="Doxquzme, post: 8867724, member: 689267"] That's fine on the amp, once in place you can always upgrade it later, always like to give people options. The stats are very confusing to most. The output is relative to the fuse rating and on brands that claim MAX power instead of RMS as the selling point, it's the way I get that rating. If you take voltage of 14.4 (the industry standard) and multiply it times tha fuse rating of 50A, you will come up with 720 watts. Then multiply that by the amps efficiency of (optimistically) at 80% and you get 576 watts. Knowing the brand, probably closer to 500 - and it will do close to that - hopefully. The Massive website indicates the following for that subwoofer - they only have the one shallow mount unit and it is a dual 4 ohm voice coil (2) coils on each woofer, each coil is 4 ohms. [ATTACH type="full" alt="1704313213551.png"]55865[/ATTACH] On any woofer, you can have multiple windings, or voice coils. In your case, that woofer has two and each is wound to 4 ohms. When you wire them altogether to one amplifiers mono output, that amp sees it as a single load. How you wire that is what the amp will read. The wiring diagram I gave you is correct for this application, it's a series/parallel configuration. Wiring any one coil to another in series will give you double the impedance, parallel half. In this case, you are wiring each of the woofers coils in series or each individual woofer. That makes each woofer 8 ohms [ATTACH type="full" alt="1704312584470.png"]55864[/ATTACH] Then you take the two, now wired to 8 ohm woofers and run the leads together +/+ and -/- (parallel) as one +/- to that amplifier. The amp sees the load as 4 ohms. Broski probably knows this too, but might not be able to explain it as I have or based on what he perceives he is working with. Take solace in the fact that most of the responses given in this and any forum are watched and kept in check by multiple people reading the information who usually have no compunction about pointing out if something is amiss, if it were.
