Hi

I have recently replaced a broken head unit with an Alpine CDE-9880R and I am having problems with the lack of bass that can be handled by the rear speakers.

Installer said the rear speakers are pretty weak and set up the fader to be biased to the front.

i.e.

F4 on a scale of R15 to F15.

The other setting are all centred.

The sound is lacking bass compared with how my fave music

(dance/trance/house) usually sounds.

Same with the radio sound.

If I set the bass up

(+1 or

+2 on a scale of

-7 to

+7) for a sensible volume level while parked, then when I turn the volume up a bit for town driving I hear distortion from the driver side rear speaker and have to turn the volume down or reduce the bass setting again or both.

The lack of bass tolerance from the rear speakers is worse as the volume is turned up for motorway driving.

The volume scale goes from 1 to 35, and I use 6

- 10 around town and about 15 on motorways.

If I had it on max I will probably blow the rear speakers if I didnt go deaf first lol

My car is rev 3 GT turbo.

It has one storage box behind the driver seat.

The passenger side is at the same height as the driver side storage box and carpetted the same way but it looks like Toyota never fitted it with a lid.

The Alpine 9880R installer suggested it would sound a lot better with 6.5" speakers in the storage boxes behind the seats and not using the rear speakers at all.

The subs would have mesh covers so I can still put the tbars behind the seats.

I have searched the forum and not seen this setup

- has anyone done something similar?

I might go along with the Alpine installers suggestion, but I have just thought that I do sometimes put stuff behind the seats on top of the storage boxes which will affect the sound from any speakers in the storage boxs.

Maybe thats why Toyota mounted the rear speakers high up? Although didnt Toyota also do some cars with subs as well?

Anyway, I would appreciate your ideas on how to get the bass sounding right.

I want the bass to blend in with the overall sound.

cheers
