the subwoofers attached to the rear deck making insane noise.after half
volume we loose the quality we have on half volume. before half volume
and normal volume works very clean crisp on tweeters and so nice on
woofers deep and clean bass but not high what we want to make it work
is high volume clean bass, .. but woofers are killing us after half
volume , bass is starting a strange sound it still hits but normally it
sounds like clean bam bam bam,then reaching the half volume then starts
bamwwww bamwww bamwww(sorry about my expression) what we need is very
deep clean bass. we donot hesitate to spend money but we donot want to
pay 1000$ to circuit city to install to what we have in our mind. they
offer us 1000$ even we supply all parts amps power cables and speaker
wiring we give them so we decide to install ourselves we already invest
quite money. no problem if anything missing on you guys opinion please
post. all be appriciated we really need help. we really want to make it
work ourselves.

very thanks. sorry to take you guys times..
