jmiller2496 0 Posted May 7, 2014 There is power to the amp. It has to be something with the remote wire. There are two amps. The first is for the speaker, that gets the remote wore from the stereo then there is another remote wire that goes from there to the amp for the sub. When I was testing the remote wire the light for the sub amp turned on but shortly after I took it off it shut off again. Any ideas? Everything worked good last year.

MLA 1,048 Posted May 7, 2014 did you actually measure the voltage across the terminals? measure the voltage across the amps ground terminal and the turn-on terminal? Go to top Share this post Link to post Share on other sites
airking26 0 Posted May 7, 2014 Check both12v lead + 12 v remote wire with multimeter. If the both look good you may have a bad ground or your amp is toast. Go to top Share this post Link to post Share on other sites
David 363 Posted May 7, 2014 After a long winter there is always a strong possibility of weak voltage.Two amplifiers may not have the identical turn-on voltage threshold.Check the voltage across the amplifier terminals just like MLA suggested. First check across the primary terminals and then check across the remote trigger (with HU 'On') and primary ground terminal.A poor ground will be indicated by a low voltage reading.Then also measure across the battery terminals.If one reading is substantially lower than the others then this will help narrow your focus.Using a multimeter and measurements in general can often put a quick halt to the ongoing speculation.

Slyexe 32 Posted May 7, 2014 you could always eliminate the other amp, try connecting the power + remote from the other amp and see if it powers up normally. Go to top Share this post Link to post Share on other sites
jmiller2496 0 Posted May 7, 2014 Should there be current (wire tester light up) through the remote wire? Cause there is none. I don't think the battery is weak it had plenary of power to tie the engine over. Sent from my iPhone using Tapatalk Go to top Share this post Link to post Share on other sites
MLA 1,048 Posted May 8, 2014 Do not test the amp turn-on circuit with a 12V test light, unless it is an LED test light. Those with a traditional incandescent automotive bulb, can actually smoke the circuit inside the head-unit. Go to top Share this post Link to post Share on other sites
jmiller2496 0 Posted May 19, 2014 Does anyone ever see people having issues with stereos after winterizing with shrink wrap? It wasn't a marine stereo but is that a realistic cause? Sent from my iPhone using Tapatalk Go to top Share this post Link to post Share on other sites
MLA 1,048 Posted May 19, 2014 Wrapping up a not so dry boat for the off season, or having the wrap leak a little, can be rough on electronics, carpet and vinyl. Corrosion can be accelerated on non-marine electronics in that case. Go to top Share this post Link to post Share on other sites
