1000 Watts 4 Channel Amplifier - In Phase IPA1041

InPhase IPA1041 

InPhase amplifiers are made to rock your world. With great muscle also comes refinement. Advanced features such as bass boost, fully variable zero to 60Hz subsonic filters and crossover networks with different frequency bands for highpass and lowpass, you will always have full control. Connectivity is excellent with high level as well as RCA inputs and a pass through RCA output to feed more amps, without needing multiple runs of RCA cables. With two ohm stable designs, trimode capability and clever protection circuits, these hand-built powerhouses will take anything you throw at them. Massive heat sinks with a high surface area to volume ratios and cast end caps to hide the wiring connections and keep things controlled – helped by forced air cooling on the real bass monsters. All the amps may be bridged for even more power into one channel. Four and two channel designs, all with potent MOSFET power supplies, cover every need from single-amp whole system solutions, all the way to pavement-shaking power mania. There is always a high quality InPhase amplifier (or two) that’s just perfect for your hunger for power.

Great Amp
Jamie on 20/09/2016 5 star rating

This amplifier is excellent value for money. My old alpine went down and replaced it with IPA1041.It sounds so much better clean and dynamic. I have set the gain half way. Would definitely recommend it.

good quality for a budget
marco on 19/09/2016 5 star rating

I'm using one of these in my Honda civic, running some inphase 6 x 9's and an XT12 subwoofer and for its power ratings I'm very impressed

great value
matt on 29/05/2015 4 star rating

This amp is great value, It controls my speakers really well helping them produce all the fine details in quality sound. Loads of adjustment too. Yes you get what you pay for but you can't moan at the value for money you are getting.

  • Question: 19 November 2018
    Car: Audi TT - 2006> (8J)

    Could I replace my bose amplifier with this item.
    Many thanks.

    hi, if your bose amplifier is 4 channel then yes you can, if yours has the subwoofer then you will require a 5 channel amplifier

    Found Useful? Yes 

  • Question: 03 April 2018
    Car: VW Transporter - 2005 >

    Does the 2 year guarantee on this amp exist if I fit the amp myself?

    Is it bridgeable? Need to run 2x 6x9 + dual core sub.

    the warranty doesn't state it has to be installed by a professional, if the amp is damaged due to incorrect wiring the component damage would tell them that anyway. you should be ok to run what you have based on that the subwoofer has the correct coils

    Found Useful? Yes 

  • Question: 29 January 2018
    Car: Vauxhall Astra - 2007>

    Hi, What gauge wire do I need to power a in phase 1041 amp and a alpine cde190r stereo. Thanks


    an 8 gauge cable kit would be ideal for this amplifier
