Hi,

I am looking for some advice about the best way to get quality bass into my 320 Saloon.

Currently use a Becker Mexico pro, Ground Zero amps, speakers inc sub.

The sub is in a box in the boot, connected to the same channe as my rear component speakers. Nt happy with the way the thing integrates, would a custom enclosure help?

Any thoughts greatfully received.

Chris

well enclosures for the sub does add alot to it's SQ...but also the sub itself can mean alot...dont really familar with the 320 saloon..but also if your sub is connected to the same amp as your rears that could be the problem that your not gettign enough power to the sub..you might want to think of gettng a mono block amp to power that sub. and also you dont need a custom enclosure just a good box.

Thanks

The Ground zero amp (http://www.ground-zero-audio.com/13_download/manuals/manual_gzna.pdf) is connected as shown in the manual. Thought is perhaps separate monoblock for the sub or running the two main speaker sets of the front channel and the sub off the rear.

What do you think?

Chris

what year is the 320? E36 or E46 bodystyle?

If I read your post twenty times, it still looks like you have the sub and the rear speakers on the same channel?

This is a no-no.

Giving a sub it's own monoblock often helps with volume and quality issues.

Hi,


You are right in that the sub and the rears are on the same channel, with an inductor to adjust the crossover of the sub as per the manual.

The car is 6 months old so not quite the latest style which is just being launched. It is a saloon so the sub is effectively in the boot / trunk and for me the issue is getting its output into the car. Center arm rest down and the cloth pulled away allows the speaker to output into the main body, is this accepted practice?

Suggestion for consideration is using the Becker's amp for the rears and one channle of the GZ amp for the front and the other bridged for the sub. This seems to make sense to me

What about you?

Chris

just use one amp for the sub and one amp for the speakers..if you are going to bridge any amp bridge the speaker amp..you just want the sub to connected to one amp..and that amp to be connnected to that sub ONLY...

Hi

I am new to car audio and think i am confusing things. Let me try to clarrify.

I have a head unit with internal ampflication. The head unit is feeding a 4 channel power amp from its pre-out (link to pdf doesn'r seem to work but if you paste the location into your browser it will get you there). The power amp is four channel.

I am proposing to use the internal amp of the head unit to drive the rear speakers. This leaves me a four channel amp to deal with front speakers and a sub. My plasn is to use two channels to drive the front speakers leaving two channels which i am going to bridge to drive the sub.

Is this feasible / appropriate?

Sorry if this is a daft question

Chris

if I understand you correctly your gunna hook up the front speakers to the 4 channel amp and then hook up the sub by bridging the rear speaker outputs? If that's the case it should work fine if you don't use the amp as the filter for your frequencies, which means you'll have to wire seperate crossovers in between your amp and your speakers. This is the only way to do it for everything to sound appropriate but it's a lot more difficult than saving up for a mono amp and wiring it into the system. Let us know the specs of your sub and someone will recommend a good amp depending on your budget.
