Smile newbie needs help with audio in zen.

hi all,
Need your help and suggestions to improve sound quality of my sound system.
i purchased a zen in end'05 and this is the config i have gotten installed uptil now:

1. Pioneer deh - 080 mp head unit (gift from maasi in new jersey! how i love her!!)

2. pioneer 6991s 6"x9" speaker set

3. pioneer 306-c sub woofer

4. 2 nos. sony 222 amps ( one powers the sub and the other powers the speaker set)

5. i-pod connector from pioneer

6. wires and connectivity kit by boss audio

i have installed the speakers and the woofer in a single large box with the sub in-between the 2 speakers.

the amps are mounted behind the rear seat back rest. the sound is extremely clear and crisp till volume level 4-5 only.

after that the woofer emanates a jarring sound and the overall quality of the sound doesn't remain that crisp.

please help me sort out this problem within 6-7 grand.
would really appreciate all your suggestions.

regards,
anuj

if u get the maximum power at 4-5 volume, after that the clipping occurs
this problem can be solved in just 1 rupee.

you need to add some resistance in line from the HU to the amp.
then you will get max power at say greater volume instead of 4-5
start by connecting 10K ohm reisitor.

Am i right sam and navin or is there a better idea.

do you feel you need more volume? if not try by setting the input levels on the amps to a lower level.

also it wont hurt if you isolate the 12" woofers from the 6x9s.

and lastly if after you have tried the presets if you still need more power you would need a bigger amp than the 222 for the 12" subs.

I agree, you need a better amplifier. Sorry dude but the 222 is a rubbish amp. and cannot power a woofer.
amit, he isnt saying he gets max volume at 4-5, he says it cracks after that.

Definitely you need to lower the gain settings on the amp and lower the pre out (SLA) from the HU

Turn down your amp gains. Your amplifiers are not setup properly for that HU's output voltage. Problem is, that amp is too tiny to move that sub properly. consider a sub amp upgrade.

the alpine 240 is not really a sub amp. the 222 while not a great amp will suffice to run the front and rear. with a good sub amp you could bridge the 222 and run one for the front and one for the rear.

The problem Doc, is that the Sony 222 does not drive a sub properly.

Well the Alpine 240 is way better than the 222 at driving a sub... the 222 sucks in just about every way possible

For the price the 240 woudl be better used for midrange. a cheaper amp like the JBL 60.2 (half the price of teh 240) could be used.

navin,
when you say isolate the sub, do you mean house it in a separate box or connect it to the sub-drive output from the head unit. if its the latter, i have already done that so i can control the woofer output separately from the two speakers installed on either side of the sub.
