whats up all I just upgraded my speakers from factory to Pioneer TS-A6870R 6x8's...and i currently have a head unit of 50x4 Pionner MP3...heres where my problem begins. Just finished installin speakers...back and front right one are perfect...BUT...left front has a vibration noise...i know its not the speaker because it was soundin perfect and takin the bass up to a level of 40...my friend told me i could use some type of insulation...would that work...any other suggestions would be appreciated..THANKS
1: use baffles for the speakers (foam baffles) 2: use bass blockers to stop them from bottoming out 3: don't drive the head unit at full volume. anything above about 3/4 volume (around 30 out of 40) will put the internal amp into clipping which will damage your speakers.
yes, and dynamat actually sells baffle kits for door speakers.
the real problem is most likely trying to play the speakers too loudly with head unit power. if you want loud and clean, amplify the speakers, and use a high-pass filter for them set to about 100Hz, 12 to 18dB/octave Q.
