    It gots the job done

    Posted by Ismael Castell Uroz on 24th Sep 2020

    It includes everything needed for a basic installation on your cabinet. The quality is not excellent but it wasn't in old arcades anyway. moreover, it has more than enough power.

    Ample Amp!

    Posted by Andy J on 23rd Feb 2017

    This little kit provides ample volume and sound quality for playing old arcade games.
    I had had no problems installing it or with interference etc just remember to keep all your sound system cabling away from power cables!

    The kits is nice, but it has a big flaw it doesnt come with a 12v 2a transformer it only brings to cables that you have to conect/solder to something that gives you 12v power so you´ll problably have to buy a 12v 2a transformer...

    Not bad

    Posted by Unknown on 17th Jul 2014

    The speakers and the metal grill looks good, the amp feels pretty cheap but it's not meant to be seen, so that doesn't matter.

    There is however quite a bit of hum introduced to the audio. Not sure it's grounded that well.

    Also, no screws come with the kit and I've no idea what ones to use, either, which is a pain in the ass. A shame some screws couldn't be included, or suggestions as to what diameter the should be,
