  • Rated 4 out of 5 by 2 reviewers.
    Rated 4 out of 5 by does what it says on the box easy to fit and set up sounds nice and clear with good power. only downside is if (like me) you need to mount it in the car the cooling fan runs quite a lot and you can hear it between tracks a small thing but quite annoying at first i thought i was getting some sort of feedback. However if your mounting in the boot compartment as is the norm this will be more than adequate. 06 November 2015
    Rated 4 out of 5 by Nice bit of kit with an above average performance Nice bit of kit with an above average performance, easy to install and to adjust but remember to put the end caps on before you wire it up as you will need to disconnect it after! Bass is good (running into a 12’ sub) deep and low with a warm rumble, top end is bright and clear, I have the unit connected in a 3 way mode and it takes a while to adjust the setting to get the sound right, there is a low end and high end switching so you can get the best out of it. There is a small fan on the bottom of the amp I didn’t expect, obviously there to keep it cool but you need to bear this in mind when mounting (fitting supplied to allow this) Ultimately a good solid amp that works great, others out there for a similar price just a lack of choice when it comes to specifications so worth the cash. 21 September 2014
