I have phase linear uv8, need to know how to get subs 2 work! Amp goes into protect mode when rca's r plugged in, there r 3 sets of preamp out puts 1 front left and front right, 2nd is rear left rear...


try testing the amp without speakers plugged in. Run the sub preamp out to the amp that you will drive the subs with, but don't wire up the subs yet. Test for protect mode kicking in.
Yes - unplug the rca ins from the amp. retest.
No - Problem lies within the sub wiring. What is the load on the amp (measure with an ohm meter)? If it is below 4ohms, chances are the amp can't dip that low. Give it more resistance by wiring it differently (series vs. parallel)

I have a alpine MRP-M500 amp connected to 2 10 inch comp kicker subs. The problem is the subs rattle and distort. The subs have been tested ok and all the wiring has been tested also ok. What could be...


Any time that there is a rattling sound from the subs, that indicates that they are probably blown. How were the subs tested ok? If the resistance of the subs is still close to OK, that is good, but it doesn't necessarily indicate that they are working properly.
Try using different subs at a lower volume, or turning down the gain slightly.

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...


:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

No signal from sub connected to NAD T760 in test mode.


Try using front pre out to the sub from the receiver. the crossover is in the sub anyway. If this works change your settings on the receiver and test again. If sub is still inop, could be an internal issue with the sub amp. Does your sub amp have an on/auto/off switch or light? check that as well. Hope this helps, if you need further assistance, send a reply and I'll help some more

Subs wont play


Hello debrahood196,

You first need to determine what is causing the "no sound" problem. (1) Try the sub(s) on a different amp (a friends maybe, or a local audio shop) and make sure that it/they work properly. (2) Test the outputs from the receiver. (3) Try a different pair of RCA cables. (4) Check the speaker wiring. (5) Check your head unit settings. (6) Check the amp gain. Once you have isolated it, repair or replace the defective wiring or part.

Hope this helps.

One hits harder then other


Check the Polarity on the subs, you might have to invert one. Best way i know of to test is get a BASS CD -=download a bass test cd...legally of course=- and check for a test that will just flutter the speakers in and out and see if they both go in and out in the same way, if one is in and the other is out that could be your problem
