    I am thinking of replacing my III JBL audio system. I want to replace the HU, AMP and speakers with an aftermarket HU, AMP, speakers & sub.

    - will this void any warranties?
    - will this cause any problems with the 12V battery?

    It will only void a warranty if they can prove that your modification was at fault for whatever claim you're trying to make. That is the law. :)

    No, it will not cause any problems for your 12v battery unless you play the system for extended periods of time with the car off just as in a conventional vehicle.

    With a very high wattage system you may continually drain down the small stock 12v battery and it would be advisable to purchase and Optima deep-cycle battery that can better handle being drained regularly.

    Thanks for the reply.
    I will be installing a amp (4x125 RMS at 2oms) & a basslink sub (200 watts).
    Would I need to upgrade the battery?

    Depending on the brand and how you wire it up you may not see that much but even if you did I think you are fine. I ran my 1,500 Watt RMS amp for a couple years before I replaced my stock 12v battery.

    Someone else has done something similar (they kept the JBL amp) - I guess there is a wiring harness specific to the JBL system - i'd start with that...

    I was told that if I keep the factory HU I would have to use a cleansweep because I would not get a clean signal? Instead of spending the money for a cleansweep, replacing the HU is about the same $$ + I will get a direct signal - also the aftermarket HU is much better.

    I have the JBL system.

    Does anyone know what wire harness I will need to use for my aftermarket HU so I can retain the hot,ground and ignition?
