Bridging two12" subs and one 15" sub to my Rockford fosgate T 1500bd amp


assuming all 3 subs are 3-4 ohms, running all 3 in parallel (the 3 positive leads all attach to the amp positive terminal, and all 3 speaker negative leads connect to the amp negative terminal) will bring you at or above 1 ohm, which the amp is capable of handling. With 1500 watts, you will want to use 8 gague power leads for the amp, 12 gague speaker cables, and an inline 120 amp fuse between the amp and the battery, within 1 foot of the battery.

I have a Sony STR-KM7 AMP and the subwoofers have stopped working?


Sorry but it sounds like the subwoofer voice coil has shorted, you will need to replace the sub.

So how do wire this set set up to a bridged amp any help would be appreciated


assuming that is a dvc dual 4 ohm speaker, and you have a 2 ohm bridged amp, you run a positive from each side of the speaker into the bridged positive of the power amp, and run a negative from each side of the speaker into the negative bridged terminal of the amp. if, indeed, you have 2 4 ohm voice coils, running them bridged in parallel wiring will bring the load to 2 ohms. if you have 4 voice coils, of 4 ohms apiece, you could run all 4 parallel into the amp, but that would bring the load down to 1 ohm, and you would have to make sure you8r amp can support 1 ohm operation.

What do you think the problem is as to why my ipod want load up,i keep getting the message ipod communication aborted.


bad receiver in the radio, or, the transmitter on the ipod is bad. try it on another bluetooth source to see if it maintains connection, if not, the ipod could be damaged or bad. If it works with another bluetooth source unit, then the radio has a bluetooth receiver issue.

We sell low priced replacements!

JVC KD-R330 Won't turn off Demo mode - tried instructions. Every time I follow the instructions (Turn on, Hold Menu, push "vol" button, change to Demo off...etc) It doesn't work. In fact, as soon as I...


Hi,

Do you have a Bluetooth adapter plugged into the KD-R330?

A compatible Bluetooth adapter (like the KS-BTA100) usually plugs into the rear auxiliary port of the receiver. It then needs to be "paired" with your Bluetooth device, for example, a Bluetooth phone headset.

What you're describing sounds like what can when no Bluetooth device has been "paired" yet.

If you don't HAVE a Bluetooth adapter connected to your KD-R330....is it possible you accidentally plugged something into its rear auxiliary jack? Or the front auxiliary? In other words, is it possible your KD-R330 receiver is mistaking some other device for a Bluetooth adapter?

Don't know if that helps at all...if there's no adapter issue, and nothing connected to the AUX jacks, probably your next step should be a call to JVC, or whatever number you were given for tech support.

On the bright side, since the receiver turns on, and responds to some commands, you probably didn't mess up anything major in the wiring. And, there's also the possibility the receiver is defective....certainly if this continues, and JVC can't help you, trying a replacement might be worth a try.

BTW, feel free to post a reply...I'm going to look further to see if there's any other documented issue besides an adapter that might cause the problem you're having.

Lightning audio b150.2 as soon as +12 is hooked up blows 25 amp fuse and the c2 1000uf/35v capacitors blow???????


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you.
