Hi I just got this amp today and its pretty much gona blow the trunk of my car off. I was wondering how to power this amp for use in my home. Im not sure about the amperage it needs. Also if i get a power supply tha has a bit more amp rating than the kenwood will it damage the amp.

Re: Running amp in house
Its very tricky to use a car amp in house, your going to need a power converter and deck for the house, plus car audio is not made for home, the sound is going to be off cause car audio plays a differ frequencys the home sterio.

Check the fuse sometimes when hooking them up youll blow a fuse.but make sure your ground is to bare metal no paint should be on it. very important.. also make sure the blue wire has current using a light tester or volt meter. if you have a long wire run it directly from battery to see if its the remote wire . sounds like a bad ground is the amp new what is the brand
Make sure there's no missmatched impedance. If your sub running 2 ohms then your amp has to be 2 ohms stable. Does the amp blow fuses or get really hot? If it does it can be a fire hazard and I would recommend taking it out of your car. It could be that you don't have sufficient grounding. The grounding needs to be very close to the amp and the paint needs to be thoroughly scratched off. Otherwise could be a blown transistor within the amplifier, you can check this by opening up the amp, running a multimeter and testing the transistors for resistance.
Your amp is blowing fuses to protect your circuit. The type of 12V battery does not matter. For whatever reason you are over driving the amp. 2 Ohms sounds like a very low impedance for a car amplifier output. I am assuming you have the two 12" speakers wired in parallel. Most are rated at 4 Ohms which means you are pulling twice the current with the 2 Ohm load. Also, the bigger the speaker, the bigger the magnet, the bigger the coil, the larger the inductance, the heavier the load. Make sure these speakers are matched with your amp. A small amp driving large speakers will shut down at high volumes. Try putting them in different channels. Good Luck.
its your fuse box. i would bypass the fuse box and wire this amp directly to the battery via monster cable. make sure you attach a 30wieght fuse to the monster cable that is running from the battery to your amp. ground the amp against the trunk. scrape the paint of a section and drill a hole in the trunk. use this for the ground for you amp. this will fix the no power issue.
Sounds like maybe you are not getting enough power to your amp.
It sounds like you have a pretty powerful amp and it could be you don't
have a large enough cable going back to your amp. If you have
access to a volt meter then you could take a reading of your "12volt"
power connection at the amp while stopped and amp running to see if you
do indeed have 12 volts or better. If it is getting down to 11 or
11.5 volts then you will need to improve that. I have a saying
that when you have a huge amp you must wire it as if you are trying to
power your cars starter motor from the trunk and wire
accordingly. And that means your ground connection too.
Don't forget the ground connection from the battery to the car's
chassis. Maybe this will help. Good luck.
And theres your problem. You can't run 3 speakers on it at once. BIG NO-NO! It can only have 2 ohms or more on each channel or 4 on the bridge. Three speakers is gonna be WAAAAYYYYY below that. You need to correct it ASAP, or it's ALL gona blow.
A dual voice coil speaker can be wired to be a 2 ohm speaker or an 8 ohm speaker depending on whether you wire it in series (8 ohm) or parallel (2 ohm). When you bridge your amp then the two channels will share the load from your speaker. If the speaker is wired as 8 ohm then each channel of the amp is driving a 4 ohm load which is fine. If you are bridged into a 2 ohm speaker then each channel will be driving a 1 ohm load, which is a very very heavy load. Is your amp designed to drive a 1 ohm load? If not then that would explain why you are having a problem.
Hi , now that you have the amp apart , just check the underside of the printed circuit board and check for any corrosion ,rub it with a soft brush . then try connecting without speakers . see if it still blows fuse, if it does then there is a likelihood that your mosfets / outputs may have shorted the first time you reconnected it .
