Sounds like a bad rca connection. You need both rca jacks to be plugged in from your head unit, both left and right or you will not have full power you'll have half power to your sub/subs. Check your sub with a volt meter and see what it reads. Make sure if your head unit has a sub volume make sure it's turned up. Alot of people don't realize they have a seperate subwoofer volume on there deck and it's set to low, so check that. You could have bad rca cables. If all that is ruled out(best way by trying a different amp) the amp itself might be having problems. Don't think it would be in protect mode either. Let me know if you have'nt allready.
First of all, you need to isolate what is causing the problem. No output (sound from the sub) could be a defect in the 1) Wiring, 2) Head unit, 3) Speaker(s), or 4) The amp itself.
Start to systematically eliminate the possible causes. Connect your subs to a known good system. If they work, it's got to be something else. Check the RCA cables from your head unit to the amp. Check the speaker wiring. Check the amp on-board fuses.
Make sure that you have output from the head unit. With multiple RCA jacks, it's possible to plug your cables into an input rather than an output (in the dark, behind the dash). If you have more than 1 set of preamp outs, try another set.
no it doesnt HAVE to be wired in it just lets you control the amount of output from the sub. however the spark could have blown out the internal workings of the amp. there are genereally multiple fuses on car amps. have you checked these? if they are blown replace and reinstall if not then it very would could be that the spark caused the amp to fry.
This sounds like a problem with the head unit output to the sub amp. Are you using a Pioneer head unit? If so, you may have a problem with some surface mounted fuses inside the radio on the main board. Certain Pioneer head units have a common problem with these fuses blowing. They are fuses for the ground on the RCA outputs.
Let me know if this is the case, and if it is I can give you the part number of these fuses and tell you where they are located, but you would need good soldering skills to replace them. Also let me know what model number your head unit is.
That depends on which wires you are referring to. High level inputs or low level (RCA) outputs? If you are thinking about trying to wire the amp up to your Pioneer direct, ie; running the power and ground off of the factory harness, think again, you'll fry your electrical system. You need to run a seperate power kit (8 gauge minimum; 4 gauge pref), then run RCA's from the line level outputs on the Pioneer. If you are planning to run a sub with the Soundstream then run your RCA's from the Pioneer's sub output. Let me know if I can help you any further.
it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs
Ok This is a two channel High Current amp. It is stable to one ohm. If the Subs are single voice coil at two ohms the they have to be wired in Parallel that means (Red +) (Black -) are connected to the + and - of another sub and then the (RED +) (Black -) from both go to one output channel of the amp. You pair the other two in the same fashion on the other output channel. If you are getting no output (sound) at all first check if the amplifier is going into protect. (Usually indicated by a red led on the unit. If it is connect only one Sub to each output and see if the protect LED goes out. If it does then you should have sound at the subs. If not check that you have the sub output enabled on the HU some head units do not come with the sub output enabled on the HU. If every thig is enabled, with only one sub connected to each output and the protect LED is not on then your amp is probably blown and needs repair. Nice thing is that MA has a great warrenty policy.
Check and make sure the protect LED is off. If it is on you probably have the SUBS wired wrong
