Re: car amp

I believe the answer is both. The amp gets too hot and cuts off the circuitry and causes the amp to go into protection.
Your amp is only designed to run at 2 and 4 ohms. What you need to do is check out this site and run your subs at a 2 ohm load.

If your subs are dual voice. Run + to + to +, - to - to - in box. Run + and -, + and - to amplifier in stereo. Your amp won't shut off anymore.

I got Sony Xplod XM-ZR704 700W 4/3/2-Channel Car Stereo Amplifier and 12" sub. it play good for continuous 2 hours but after that starts tripping and goes on off. i checked all wires and connections.

Amp is probably over heating. Make sure the ohm load of speaker is good for that amp. This amp is not really built to handle a bridged 2 ohm load. Make sure ground wire is clean and tight to the body chassis.

I hooked up 1 10" type r to my 600w sony xplode

How many ohms is the speaker? You have the amp bridged going into the sub? You have the negative of one side hooked up to the negative and the positive on the other side hooked up to the positive?

It says that it is bridgable at 4 ohms. What about the input? Set your stereo about half way up. Then turn your amps gain up slowly until it is where you want to listen to it normally. Not to loud. Then when you turn it up it isn't too much.

But it sounds like you have way too much power for one speaker. Especially a ten. It takes two tens to equal one 12.

Cant turn up the gain on my amp

I believe you have a wire touching a ground somewhere in your car stereo circuit. Most likely there is a speaker wire in your dash that is the cause. Here is a reference:
Also make sure the RCA's are taped up in your dash, they will create an entrance to feedback from the amp, which will inturn make your subs go crazy. Also, unplug each channel RCA from your amp and see if it stops, you may have a break in your RCA's causing a ground.

The amp is only putting out on 1 channel

I do believe this is caused by one of your amp fuses. Depending on which + on the amp is being used. That channel has a blown fuse. have you tried running + and -, + and - to both channels to see if both subs worked? If one sub doesn't then it's a blown fuse or scarred fuse and needs to be changed.

Kickers dont beat like they should

try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..

Subs dont beat like they should

you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.

Amp stopped working after ground accidentally disconnected

yup check the fuses and the turn on wire ... usually if you knocked 1 wire ya got 2 ... the amp turn on would be a guess

Bass perfect when I drive but as soon as I drive slower it goes softer?

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.

Car Audio System Drwing too much power with 2 different Amps

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.
