Help connecting the sub

You should consult the manuals for the receiver and the subwoofer to make sure you haven't connected the sub improperly. If the amp was working normally before you connected the sub, I would look at the sub hookup first. If the sub is a passive type, and you have connected it in parallel with your main speakers, the amp may not be able to handle the extra load. You may have to get another amp to drive the passive sub. If you have an active sub, you may not be using the right input/output connections between the amp and the sub inputs. Or, you may have hooked the sub up in a way that causes the amp to become unstable. Check the manuals. If you can't resolve it, come mback here with a lot more detail about your gear.

this is a dual voice coil sub. either have a 2 channel amp hook up to it. or have your mono amp have to sets of wires going out of it to your 2 connections. i dont suggest it but i have had one connection hooked up at a time played it when it blew hooked up the other connection as a back up. just make sure you have the right watt level for each voice coil.

have you got the auto ariel lead from the head unit connected to the remote connection on your amp?
if not then that is your problem, it turns the power on when you turn on the unit. and turns it off when you switch unit off.

hope this helps

If your amp has a "sub out" jack, that's the best way to hook up this sub. You'll just need a single RCA (also called "phono") cable. Connect it to the Left input on the sub, which should also be marked as "mono"

If your amp just has speaker-level outputs, then connect the left and right main speakers from your amp to the sub's high-level inputs, and then run wires from the sub's high-level outputs to your speakers.

If you're running a surround-sound setup, use the front-left and front-right speakers for this hookup.

Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

Hello montez1599,

That's a great amp.

You do not say what subs you are connecting or what wiring configuration you are using. But there should be no problem if the amp is powering up normally. I'd check the gain and crossover settings to make sure they match the subs.

Having 2 +'s and 2 -'s is just a convenience for connecting more than one sub to the amp. If you have just one sub, connect to either of the positives and either of the negatives (they're connected internally). If you have 2 subs, you can run separate wires to each sub or you can wire the subs together and then run just one positive and negative to the amp.

Hope this helps.

if you have dual voice coils connect on each seporate sub negative left channel to possative right channel of the subwoofer same to other sub then conect the left possative and the right neggative to your box power terminal same to other sub then conect the two sub outs on your box left speaker positive to your positive left channel bridge then conect left speaker negative to the right speaker possative then connect your right speaker negative to your right channel negative brigdeg to your amp is single coil hook the box its self up the same way to your amp i have two dual voice cooil 12" hooked up to the same amp that way and it rocks without the power protecter turning on

Well it should be like this...Your amp is prologic which means that it has 5+1 outputs (sub out may be for active sub).Connect your speakers on specific output for each one (center,front left,front right,rear left,rear right and sub).Other devices,CD,tuner...connect to the amp with signal RCA-RCA cabels.On the back of the amp you have all marked inputs.You wasn't specific what do you want to hook?!If you want to hook this "new" to kenwood connect rec out of it to aux in on kenwood.If oposite kenwood rec out to "new" aux in.Hope that this is what you need

Is the SUB connected to both channels? I will give you detailed instructions on how to connect a sub. Check out this website.

Make sure the BOSS isn't in "Protected" mode (Red led lit) and connect the speakers properly (check the connections if they are in "bridged" mode).
Also, make sure you set the cross-over, bass boost setting, bass volume control and the bridge mode according to the speakers you are connecting. Check the input level too.
The BOSS amplifiers are of very poor quality and it can be easily broken. Maybe yours is broken.
