    Unhappy upgraded speakers, no bass and sound tinny, whats wrong?

    I'v upgraded my standard speakers with these, 16.5cm components they have much less bass than the originals and sound tinny like a cheap radio when i turn it up (iv only done one side), iv used the crossover, the power for it comes from the original woofers cable, the standard tweeter cable is disconnected with new wiring coming from the crossover i guess iv done something wrong as there not a cheap set of speakers, any ideas whats causing it ?

    Thanks

    They need amping mate the RMS output of any headunit is too small for uprated speakers especially cmponents, also need some dynamat or sound insulation behind them aswell to give a better seal and improve midbass response

    I seriously doubt it's down to not using an amp, yeah, an amp would improve things, but the speakers should sound at least a little better than the original ones.

    Have you set the crossover correctly and/or got the woofer and tweeter on the right outputs on the crossover?

    I put vibe 17cm components in my old sxi. I didn't bother with the crossover, just wired them straight from the standard vauxhall wiring and they worked perfectly fine. Can't see you needing to amp them up, I would double check the wiring mate

    Definatly check it's wired up the right way round as out of phase speakers (think thats how it's put) will cancel out the bass

    Before you rip it all apart again though fade the sound to the front then go from left to right to see if the sound improved when it's on the one new speaker on it's own

    Honestly, i'd do what autosparks suggests, fade to front and one side, then disconnect the speaker and re-connect the other way around. If it sounds better you're sorted.

    Another to check is that on the x-over you havent wired it to something like +3db on the tweeter as that can give tinny sounds and i did it on my old infinity's.

    Should have bass, regardless if it is just the head unit! (sans amp) Sounds like what Sparks says ... however I've only seen that if 2 drivers in the same box as phased out of synch ..... Try each driver at a time, I know you have checked your headunit settings! (right? )
