I installed Alpine MRD-300 ( [URL="http://cartoys.com/cartoy/pdfs/mrdm300_manual.pdf"]http://cartoys.com/cartoy/pdfs/mrdm300_manual.pdf[/URL] ) w/ 8 gauge kit as recommended into my 08 Mazda 3 with stock headunit. I used a David Navone Engineering LOC... the sub is a MTX Thunder 12" 4500 SVC ,TA4125 (model number)... in a sealed eclosure(1.25 cubic feet) the amp powers up fine with no code whatsoever. With key on, engine off... 11.8-12.0 volts.... with engine on 13.7-13.9 volts. So good power. I redid some connections I thought were bad, and Im going to get banana plugs for my speaker terminals instead of using bare wire. The Issue: the sub does respond to bass, it has output though not very much, but it sounds muffled or blatty. Hard to explain the noise, but something is wrong, so thats my best description.
