I hooked up a punch 200m amp with a scosche 50 amp fuse to my battery and had the amp hooked up to my 12 in fosgate sub and then turned my system on nothing so i hooked the sub up it is working fine but i cant get the amp to work

this is a full-range amp suited best for full range speakers,however it can still be used for a sub. you want a sub whose max RMS is 150 watts or less.

Look on your speakers to see what ohm they're rated at currently. To get 4 ohm speakers to 2 ohm, simply wire the speakers in series. Meaning that you hook #2 sub to #1 sub and then to the amp. So you will have 1 connection to the amp but you'll be operating 2 subs. Hope this helps

Sub amps are pretty straight forward.....Hook up you rca cable....then all thats left is you positive (B+) that goes to your battery....the negative that you should hook to a good paint free bolt in your trunk and the remote wire which connects to your stereo.....

You probably have too much hooked up for the size of your power supply which is presumably a small car battery. You either need to get:

A) New, better bigger battery.
B) Capacitor in series with battery.
C) Both of the above.

must be higher than a 12 or your not getting enough amp or watts as you can je

Does the amp heat up if you power it up with no speaker wires connected to the amplifier's speaker terminals?

your cd player cant handle all the power, time to upgrade to a cd player with at least 80w10

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

2 subs and 1 amp

There's a lot more factors involved than that.

• Power capability of the subs
• Type/size of the sub box
• Allotted space in the vehicle for the sub box
• Voice coil impedance of the subs versus the capability of the amp
• Etc.
