Coax systems all shit!!!!!!! Who knows alternatives?

So, I’ve already written in my other posts about installing home hi-fi speakers in my car, because what I’ve had in my car so far was just shit, really! Up to now always 3-way coax systems on the rear shelf, they didn’t make it, even the infinitys with supposed 100 watt RMS were just as good as the Pioneers with 50 watt RMS, so something is not right 🙂 and the basses can probably be noded at all, well suc I’m a reasonable substitute, it can’t be that you put hundreds of euros for such garbage, right? Who can recommend something reasonable for my rear shelf? Bass best up from diameter 20cm 🙂 Who has the coax system from Pioneer, model TS-E2095 and can tell me how they sound? Doesn’t want to make bad experiences again… What about these compo systems? Are they better, also from bass? Listen to everything from pop to rock to techno and dan ce… Will finally have reasonable basses *g* without a sub, I guess that’s still coming. I’m grateful for every tip! P.S.: How about the home hi-fi speakers, usually you would have to pack them in the car, right? Mine of course only the chassis. Now don’t come to me with your 8 ohms, I switch them in parallel 🙂 Mfg! DannyNRW
