Hope someone can help me out. I have 2 12" Alpine subs in a bandpass box hooked up to a Phoenix Gold QX 180.2. The box has 2 wiring connectors; one to each speaker. If I try to bridge the amp by joining the 2 positives and the 2 negatives together it sounds like crap and amp keeps cutting out(overheats). If i hook up one to each channel its fine but not enough punch and amp does not overheat. By the way amp iis a 2 channel amp.
Any ideas would be geatly appreciated.

 

sounds like one sub per channel is all you're going to get out of that amp. if you want more power you'll have to get a bigger amp.

 

What model # is your subs?

 

The Alpine subs are VR 12

 

Subs are Alpine VR12. Not sure of power rating on them

 

Alpine VR12

 

How many ohms are the coils? Is your amp 2 ohm stable?

 

Darn...couldnt get thru but then all messages show up....sorry.Not sure how many ohms coils are but amp should be able to run 2 ohm stable. Phoenix Golds are always good for that

 

I would think so. In looking up the subs they seem to only be SVC. for sure. Do you have a digit multimeter? If so check the terminals on the box to see how many ohm the speakers are. This is the only way to tell for sure. I wouldn't keep driving your amp into protection, until you have a chance to find out why.

 

It should also be written on the magnet.
