Hi all
Are there any audio gurus out there?
My stereo in my soft dash does not give a brilliant sound, the head unit is not original and is a Sony one, the rear speakers are also not original. The issue I have is the sound has too much bass, despite turning all extras off there is still too much bass. Could this be an amp problem and if so is the amp in the boot oposite the spare wheel?
Thanks in advance.

You could try running a loose pair of speaker wires direct from the head to the speakers (disconnect the ones currently connected to the speakers). That way you'll take any amp out of the system and get a this-is-what-it-sounds-like result direct from the head unit. Also, check all the settings on the head unit. The Sony units have Xplod and all that carp on them and sometimes, even if it looks like you haven't set any EQ preset, there can still be factory preset levels that I always find way too heavy on the bass. Or try the custom option and wind the bass down and the treble up.

As above, it will still have some moderate EQ 'tweaks' on it.

Check the quality of the speakers, also check the wiring as most cars have a tweeter and mid range woofer feed some have inline filters. If you wind the treble right up does the tone/quality improve?

Not familiar with your set up and there is always a possibility that your system may no longer be standard, (although that should be relatively obvious to see once you start looking at your current installation), but do you have combined bass and mid-range speakers in your doors/interior as is the case of the P38's?

My P38 uses 4 x 2 channel door amps and one channel drives the bass speaker and the other channel drives the mid range and tweeter speakers.

The P38 also utilises a sub woofer unit, (with intregal amplifier), located in the rear loading bay area and this provides the very low bass notes, (the very low frequencies are 'felt' as much as they are 'heard'), and it is very difficult to determine the direction of where bass notes originate from - hence the reason why many home cinema systems only use a single sub woofer.

If this were the case your mid range speakers could be shot or you could have a problem with the amplifiers that should be driving them.

If you only have a straightforward system, (single amplifier in head unit and single wide frequency speakers), then your amp equaliser/tone settings could be stuck on the bass side or your existing speakers could be shot, (although I would expect them to rattle and crackle, if this were the case, whereas I am presuming your bass sound is distortion free)?

My Grand Cherokee has the main, (multi channel), Amp under the rear seats and I have never paid much attention to it although I have a suspicion that I doesn't do anything now as my Jeep has an after market head unit fitted.

Sorry that I can't be of more assistance.

Many thanks for the replies I will try turning the treble up and see what happens, I changed the rear speakers as I initially thought they were the problem. I think that the rest is standard RRC set up.
