My Amplifier shuts off at high volume

Basically, at low power the amplifier is not asking for a lot of power from the electrical system to power your sub woofer. For lack of a better term and probably the best way to explain it is. It uses up all the power in the wires leading to it at a high volume, and has to wait for more. Kind of like when someone squeezes a garden hose when your trying to use it. That would be the high volume, starving the amplifier. The capacitor stores power in it to power the amp at high volume. 2 farads would probably be bulletproof on a single amplifier system, but 1 farad should work well enough. Or seek help from an expert on exactly what size capacitor you should use. If you find yourself saying: My amp cuts out.

If this assisted in solving your problem, please take the time to rate it, as I took the time to write it. Thank you.

how to splice a sub-woofer to speakers


Normally the sub woofer is driven by a separate amplifier, unless the main speakers, such as in a pro audio setup have a special LF out set of terminals on the back of the speaker cabinet, in this case there is a hi powered low pass filter, fitted in side the speaker to route the LF energy to a sub woofer. Else you need a line lever LF signal spliter and a power amplifier to connect a sub woofer.

can i power 2 12 subs a rockford punch z and a xplode with this amp i found all this **** in my garage and i need to know if it will power all this


First of all. Using two different kinds of sub woofers, is not an option, as these two sub woofers have different specifications and you should never mix sub woofers. Now the better choice from the 2, would probably be the Rockford. (cant be sure without knowing the models, power handling is also a factor in how well either of the sub woofers will play, but Rockford as a rule makes better sub woofers than Sony does) In my opinion, both the sub woofers deserve a better amplifier than what Boss has to offer. However to connect either of these sub woofers, you would need to determine how many voice coils it has and how many OHM the voice coil/s are. If it is a DVC (dual voice coil) and each voice coil is 4 OHM or 2 OHM, then you can connect one voice coil to one channel of the amplifier and the other voice coil to the other channel of the amplifier. If it is a DVC 2OHM you can also connect it wired in Series/Series to give a 4OHM load and should be connected to the BRIDGE dedicated speaker outputs of your amplifier. If it is a SVC (single voice coil) and it is 4 OHM, then you can connect the sub woofer to the designated speaker outputs of your amplifier that states BRIDGE. DO NOT run the amplifier in BRIDGE mode at 2 OHM as this will probably damage the amplifier. dreamsystems

Can I hook up 2 single coil subs at a 2 ohm load on my sony xm-1252gtr?


If your sub woofers are SVC (single voice coil) 2 OHM each, then connecting one to each channel would make the amplifier run in 2OHM stereo Then again, if your sub woofers are 2OHM each, it would be better to connect both together in series and connect them to the BRIDGE specified speaker terminals of your amplifier making it run a 4OHM load into one channel. This will give you all the power the amp can give and still run stable. A 2OHM load into one channel will likely damage your amplifier. Do not forget to set the LPF (low pass filter)on if you are going to use the amplifier to run sub woofer/s. dreamsystems

alot of times its not just the amp that gives you better sounding bass.. A lot has a to do with a few other factors as well.. first off your subwoofer.. the bigger the subwoofer the deeper the bass. Some woofers exturde, or flex differently depending on the quality and structure of the woofer.. 2nd is gonna be the sub box. different size boxes will give your sub diff. depths of bass. ... general idea is the bigger the box deeper the bass. But if your woofer is not supplied enough power a big box is useless.   With that size amp your best bet is too run a single woofer. Probably a 10inch woofer would sound the best.. but it in.75cub inch. sealed box.. should sound great.

Amp not functioning right


Check the wires for a lose connection or corrosion. You may need a capacitor.
