Car Stereos: plbw124 sub, dual voice coil, watts rms


Question
I just bought a Pyle PLBW124 subwoofer, which is 1200 peak watts. I have searched far and wide, but I haven't been able to find an exact RMS number for this sub. A couple sites claimed 600 watts RMS, some others said 175, and another said 300. Do you know how to find this for sure?


Answer
Hi Tyson,

Unfortunately, if a manufacturer isn't willing to publish an RMS power rating for a subwoofer, all anyone can really do is guess; and Pyle clearly isn't willing to specify an RMS rating for this sub.

I went directly to Pyle's web site at Pyleaudio.com, looking for an owner's manual.  However, no manual is yet available for download on this particular subwoofer.  Undaunted, I found another sub with a similar power rating, and took a look at that owner's manual--but to my surprise, Pyle doesn't even specify an RMS power rating in their documentation. The relatively useless "peak" rating is all I could find.

If I had to put money on one of the ratings, I'd pick the 175 number.  That's the rating I found at PartsExpress, which is an online retailer that caters to many speaker-building hobbyists.  Because they sell a large number of raw drivers and pro audio gear, they pay more attention than some sites to providing accurate information about the products.  175 seems like a fairly low number for a dual voice coil subwoofer, but given the low cost of this sub, and Pyle's habit of publishing wildly inflated "peak" power specs for their amplifiers, I wouldn't want to bet on the PLBW124's ability to handle more than 175 watts RMS.

Hope this helps!
