I recently purchased a JL Audio 3004v2 and put some focal component speakers in. They dynamated the doors and I am very happy with the bass and clarity clear but I would like the speakers even louder.

The guy at the shop indicated that if I shut off the speakers in the headrest they could bridge all the power to the speakers in the doors.

Would it sound considerably louder or would I really need a bigger amp at this point.

Thanks,

 

I would go a step further and run a dedicated channel for each speaker in the door, not for each pair. You'll get louder as well as much higher quality sound.

EDIT: This is referred to as an "active" setup b/c you won't use the passive crossovers that came with the speakers. You'll either use the xover settings on the amplifier or in your HU (if your HU supports it) to adjust the xover for each pair of speakers (pair of tweeters, pair of woofers).

 

So it would be 75 watts for each mid and each tweeter ? The guy told me something about the combination of the tweeter and mid is considered one channel.

Given that I just purchased everything they will make any changes I might request.

How hard is it for them to change to move all the power to the fronts ? Is the adjustment simply in the amp or do things need to be rewired ?

Do you have your headrest speakers turned off as well ?

Thanks,

 

Where did you purchase from?

I don't have headrest speakers, I feel that a well tuned and powered setup with your door speakers negates the need for headrest speakers (as well as the sound imaging issues with speakers immediately behind the head).


There are two options right now:

A) Wire each speaker for it's own channel as I posted above - this will require them running more speaker wire through to each door but gives the best sound quality you can have.

B) Bridge each set of door speakers (woofer/tweeter combo). This is done at the amplifier, takes maybe 2 mins. However, the sound is not as clean as you'll have with option A.


I'm an audiophile, so I'd go with A. I switched from a well powered 2 channel system to a 4 channel system and the difference in sound (both loudness and quality) is well worth the extra effort. You already have a 4-chan amp, so you might as well make the switch.

 

And the guy was right, sort of. He's referring to a passive system where you have a passive x-over in each door, or close to the amp (wherever it is). In that kind of system, yes, each pair (woofer and tweeter) is considered one channel. However, an active setup uses 4 channels - one for each speaker instead of one channel for each pair of speakers.

 

Thanks for the info and the advice. I will see about getting each channel to be used for each speaker.

I got my stuff from Unique Car audio. I have always had good results from them.

 

Glad to help.
