How can i bridge a mtx 9500 using a mono amp?


You cant bridge it to the MONO AMP . You can only bridge subs & speakers to 2 CH & 4 CH AMPS that are bridgeable. Because if it appears that there is 2 channels on a Mono amp its so its convenient for you to hook up 2 4ohm subs to it easily But both channels are actually connect internally together in parallel inside the amp unlike a 2 channel they are separate.

So just connect your mtx 9500 to a plus and a minus and doesnt matter which since all the + terminals of are connected together and - are connected together already.

Whats important is on the side of the sub/box it reads 2 ohms. The lower the ohms the more power the Mono amp will put out. Mono amps are designed to handle 2ohm loads.

If it reads 4ohms The MONO amp is the wrong amp to use cause the power will be weaker. So if you have a 1000 Watt Mono amp at 4ohms the sub will only get 500 WATTS Max while a 2 ohm will get the full 1000 Watts.

If it reads 4 ohms connect it to a 2CHANNEL AMP and BRIDGE IT (connect + of the sub to 1st channels positive of the amp then connect - of the sub to 2nd channels negative of the amp) . The power will be doubled when you bridge it on a 2 channel amp. NOW if it was a 2 ohm sub and you bridged it to the 2 channel amp it will fry the subs and ruin the amp. 2 CHANNELS CANT TAKE A 2OHM LOAD BRIDGED OK.

2 MTX Thunder Problem.. Bridging?


Is there a option on the chanels that say ''Bridged''? If so, you can hook the subs up in parellel or series to get different ohm loads. Usually the lower ohms, the more power amp puts out. Those subs can handle 225 watts RMS whitch means the power it can handle constantly. If the amp gives more than 225 watts RMs, you could be at risk of blowing the sub. If you could give me the model # of the amp, I can be of more help.

One is broken


Does it smell funny?Smell around the top of the magnet and see if it smells like burnt plastic.If it does then the voice coils are burnt.Push down in the center of the sub if it dont move at all or has a grind the the voice coils are burnt up.Look at the lead going from the wire hook ups to the speaker cone are the intact?If not thats your problem.

I have two 15 inch L7 Solo-Baric Subwoofers and need an amp


I would recommend a brand named class D amplifier.
Connect both woofers in parallel (Positive to positive, and negetive to negetive) in a sealed enclosure. Make sure you have no air leaks. By connecting them in parallel the combined impedance will be two ohms. Make sure that the amplifier you choose can handle a load with that low of a resistance. Any high end amp should do this. Buy as much power as you can, but I would say a minimum of 1000W RMS. Beware of cheaper amps advertising "peak power". This can be considered half of what the RMS power would be (1200W peak = 600W RMS approximately).

Next, Run very heavy gauge (zero guage if you can) power line directly from the battery. Protect the wire where it passes through the body with a rubber grommet or otherwise something to keep the metal from cutting into it, and PUT A FUSE IN. I cant stress that enough. Put an 80 amp fuse in line incase you have an accident. Otherwise your car could very well burn!

Want even more punch?
Back at the amp, install the largest stiffener capacitor you can afford 1 Farad or bigger. Install this in a space where it would be protected in the event of an accident (on the inside of the strut tower or somewhere above the axle). There is a whole lot of energy stored in there that you don't want unleashed on you!

If you have any other questions please ask away!

i would go with the 801.And ithink u meant the 4501 not 4051.Both super power amps. competition stuff.your woofers are 4ohms dual voice coils.so you can series the coil on eaach woffer and use the two channels on the amp.they play at 2ohms.I think if you drop it down to 1 ohm you really be taxing you alternator that is series power.Yioou would need a special alternator.Even with them running in 2 ohms you better hav eat least a 2 farad cap.OR two batteries.. ! more thing don 't pump it up with window s closeed .you'll pop them.serious dbl. you be pumping.I'm jealous.Rating please and enjoy.
