Re: sony amp bridging

Your amp, being a 2-channel amp, should have 2 speaker connections with a negative sign(-) and 2 with positive signs(+)...Take your speaker wires (You will need 4 of them) and twist the ends of 2 of the together and put them into the negative spot on 1 side of your amp. Assuming you have 2 subs, connect them 1 to each sub and be sure they are on the negative sides of the subs or both are on the same side of the subs. Then do the same with the positive leads except to put them in the positive spot on the opposite side of the amp. So you will have the negatives from one side's outputs (or channel 1) and the positives from the other side's outputs (channel 2). Thus, your amp will be "bridged" across both channels. Hope this helps...just comment back if you need a diagram or something. And be sure to leave feedback please.

I have Sony xm-2165gtx amp 165 watt rms x 2 at 4 ohm 200 watt x 2 at 2 ohm 400 watt x 1 bridge output at 4 ohm stereo or bridge mono output 4 ohm stable in bridge mode this mean can't go lower then 4 ohm...

You can't bridge that amp onto a load lower than 4 ohms. So you can't bridge that amp onto two 4 ohm subs. To get the most power out of your subs is easy. Run one channel to one sub and the other channel to the other sub. 165 watts RMS is plenty for most subs.

How to bridge the amp and wire up two 2 -12" thats in on cabinet

if the OHM load is lower than 4OHM then you will damage the amplifier. As for how to bridge the amplifier. there are designated locations on your speaker terminals of your amplifier that state where you should connect the cables to work in bridge mode. hope this helps. If you are not sure about how many OHM the subs add up to, you could use a multimeter and set it to OHM and measure them or look on the back of the sub woofer to see what it says. dreamsystems

I Have a Sony Xplod 800 watt amp and 2 12 inch Sony Xplod subs

You should definately bridge them. Firstly, lay the 2 speakers face down next to each other. Note the connections +- +-. The first + will go to the amplifier. The next terminal(-) will be connected to the next speaker(+). Take the last(-) and connect to amplifier. Please note that your amplifier has a bridge section which is normally the first + and the last- on the two channels. Connect your woofers on the bridge.

I'm planning on installing a system in my pick-up and I was hoping I could get a little assistance. I was planning on using a pair of 5'' McIntosh ms486 coaxial speakers (120w max 4 ohm)in the front doors...

First of all use the larger output amp to power the sub. You can tell if its free-to-air if in the middle of the magnet there is a hole for "air" to flow freely. The advantage of free to air is they dont require much of an enclosure or next to none so you can mount it on a single piece of mdf wood and use the cab in the truck as an enclouse itself. I would bridge the amp for the sub to mono but be careful to tune so you dont "distort". Secondly the amp for the mid's shouldn't be bridged any maybe you could run the front and rear speakers off the same amp.. I would get an amp for rear and front speakers each and one for the sub. Your ouput rca's should goto the cross-over first then to the amp (sub) - then wired to your sub (mono) which is bridged. Ensure to tune your cross-over to lowest frequency for sub. Its easy to bridge an amp if its 4 channel.. looking at the speaker terminals it will look like ( + - + -) use the two outer most terminals to bridge to mono.

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp

Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.

Spl 6ch amp

When you want to bridge the amp... Take a look at the speaker terminal on the amp. I guess there is vritten how you connect ordinary and bridged.

Many amps have a button where you can choose how many channels you want. If you just have one pair off signal cable, you must choose 2 on the switch

Hi Trim God,


I do not reccommend that you push the Pioneer speakers over 100 watts.  The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away .  Hook up the pioneers straight to the Channels,. do not bridge.  I put Subs in my truck though.  I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub  in my Z28.  The pioneers never get drowned out.  I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
