“I have purchased this to fit it the boot of my mazda 3 and really does a good job except for few songs where some type of bass is reproduced extremely low. Not blown away but there is a bass improvement better that the speakers alone can do. I still believe that the ideal place for this subwoofer is under passenger seat not for the boot, a quite lowder and would have been very good for boot.”

“I am an audio engineer with good hearing and understanding of sound. I listen to all kinds of Dance, EBM, Dub Reggae, Metal, Classical, etc. My aim is hi-fi quality with serious bottom end on reasonable money. I installed my USW300 in a medium sized estate car that already has upgraded door mids and tweets. This underseat sub fills out the bottom end beautifully and gives you another octave of deep bass as well as taking some of the strain off the door speakers so you can set the bass flat on your head unit and let the sub do more of the work. It is NOT designed to impress musically illiterate 18 year olds or annoy public. The figures quoted (40-150Hz) are manufacturers graph figures and not real life, the usable/audible range of this is about 60-120 Hz (I know, I've miked it up to an analyzer hehe). Anyone complaining it distorts has not set it up properly, or needs to look at their door speakers first because this thing tops out around 120Hz and that is too low to get the really interesting bass detail out. The gain control needs to be between 0 and 6 and DON'T use the "bass boost" control unless its an emergency and your door speakers are crap, it just muddies the bottom end rather than increasing it because the speaker can't handle that amount of senseless boost. Anyone complaining it isn't loud enough for dance music of any kind needs to look at the REST of their system because all the thud and kick detail you are looking for will come from the door speakers in the 100-400Hz area. If you already have 100 watts or more driving the doors then you need a bigger sub than this. However, if you have a factory system under 100w and do want pure sustained dub style sub bass for D+B, Dubstep, Hard Reggae, extreme Classical etc then this will do for most people in an average car and give you plenty enough for normal use. If you want to drive round and rattle other peoples windows then this is not for you, what do you expect from a 5x8 inch panel sub? Since fitting it, I have upgraded the factory head with a small DSP unit to give total control over the crossover points and the end result is jawdroppingly good. But trust me when I say you need to make sure you have done the best you can with your door speakers FIRST (and preferably damped the panels too) because that is where all the detailed low end comes from, a sub will only give you the rumble to complete the effect. One point on mounting, it is fine velcroed to carpet under the seat but you will greatly increase the transmission and the spread if you can bolt it down properly, just be careful where you drill. Only minus point I can think of is the wiring loom supplied is a bit cheapo and the power cable is split into 2 to utilise 2 terminals at the sub connector to make up the load and continues all the way to the end like this instead of terminating within a few cm and commoning to one heavy gauge cable to go to the power source. That is bad practice if one side ever got damaged because it would *still work*, and you'd never know all the current will be hitting one side until it caught fire. OK that's an unlikely scenario (though so many people buy car hifi and just amateurly bodge it in til it works) but you have to think safety first. Oh, and the mounting brackets are a bit mimsy. I'm still giving this 5/5 though, it is a fantastic bit of kit for the price and fits anywhere.”

“I bought this sub as it had good reviews and had double the power of my current under seat sub. I was not impressed with the sub at all it is not very loud and when you can hear it it is distorted. While driving it might as well not be there at all. Very disappointing as I have another mode of in-phase in my van and that is brilliant”

“This is a fantastic choice for a small car too (Ford Fiesta) - I've not tried the Kenwood competitor (which was my original plan) but knowing what I do about audio equipment and subs/amps performing best with plenty of headroom (and reading a number of reviews of the Kenwood dying, presumably from pushing the smaller amp too hard), I'm very glad I upgraded. The USW300 is plenty, but I also wouldn't want much less. I've had a full 600w monoblock driven 12inch ported Kenwood setup in the past (in a different car), and the little InPhase unit gives me about 90-95% of the joy of that experience but with literally zero intrusion in my storage space. Very happy with the little fella”
