My sylphy come with original panasonic 6cd hu which is lack of bass,
Also no aux/line in for link the navigator together.

( hu connected with 4 speakers & navigator sound from separate 2 tweeters.)
Think of connect navigator with hu amplified sound output.
I found original hu not enough bass, not sure is due to hu or speakers.

Any advice to this ?
But no sure how is sound quality, also original speaker can fit in or not.

Should i change hu (how about clarion cx501a), or add component set only ?
Cheers.

The hu has the bass and treble control from -5 to +5 range but i fixed at bass +5(max) & treble +5 also.
But the output i should said treble is acceptable and the bass are dispointed. Some forum quoted as source are weak in bass . Need more opinion instead of spend the money to testing.

In the case of change the hu, any user can share, what model in 2din is better...
Maybe budget below 1.5k, also consider of nissan promotion of trade in to clarion cx501a; not to void the new car warranty and add 2 years additional warranty to new hu.

Any good Suggestion ? Thanks.

I has enquired to TCEAS Glenmarie 2 months ago, the wire are complimentary with the purchase of new hu, when requested by customer. Your may verify to this. RM80 is too expensive.
