As described below, I currently have an Eton 5402 and a Rockford 3115 (1000 Sinus). I have now assembled my car to the largest part and now I have heard the Rockford. So for the performance it has and the amp that is attached to it, really not much goes there. With a cheap Db measuring device I came to about 132db, which in my opinion is a joke for the components. Now the question arises to me whether the woofer over time (by using longer, since it is almost unnulled) The woofer has not yet run at all, since my car had been totally disassembled for about 2 years. The Eton is at its power limit anyway, because its clipping indicator at level already glows like wild. Electricity should be sufficient there, since I now have an Optima blue top and that is completely charged, but not yet a cap. Cables turn 50mm2. I will anyway in the next time other Woofer and a larger amp afford, but until then this should be done. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario. mfg mario.
