  • Question: 11 March 2015
    Car: Renault Scenic - 2000>

    Sony XS-GTX121LC 1000W 12" compact subwoofer in custom enclosure

    Which Amp would be able to run this sub. I want really good bass.


    The Sony subwoofers work very well with the Inphase Amplifiers , the one I suggest is the IPA 1001

    A well built Amplifier with 1000w output

    IPA1001 1000 Watts 2 Channel Amplifier

    Car: Mercedes SLK - <2004

    would like to fit this in the boot of my car could I have the W/H/D of it please


    The Sony subwoofer will fit into your boot - I recommend you buy a ported box for a better sound

    You need a good Amplifier to get the best out of that subwoofer - I recommend the Inphase IPA1001 with JW81 8 gauge wiring kit

    Single 12 inch Bass Box (Ported)
    IPA1001 1000 Watts 2 Channel Amplifier
    JW81 1800 watts amplifier wiring kit
