How to do a pro audio setup in car.

[eli346 10+ year member]

I would like to do a pro audio setup on my doors because i think it would be great for at bonfires and just for the loudness in general. Probably just a mid and tweet in each door for now. So this is a very budget build as these are going into my beater car. So what im not sure about is the crossover part. This is my head unit JVC EXAD KD-AVX1 DVD / CD receiver with 3" LCD screen at Crutchfield.com

So im going to need a 4 channel amp and a passive crossover for each side i believe? I see some of the big spl vehicles with tons of speakers in the doors how do they do the crossovers for those? I guess i just need someone to explain to me how it's done.

Those are the ones i plan on using havent really decided on a tweeter yet and do you mean 2 woofers and one tweeter per door? Is that so i can wire down to 4 ohm?

I run mine active off the HU, but in the wife's ride I use HPF on the HU and FMOD's for LPF. That's to bandpass the mids, AQ supertweeters have a built in cap for HPF....

Unfortunately most PA set ups seem to have NO xovers of any kind, just letting mids and tweets play full range. Tis one reason why PA gets such a bad rap in the ca world...

8 ohms + 8 ohms = 4ohms

get all 8 ohms speakers and tweeters

parts express has that 5k passive crossover for tweeter $5 out those on each tweeter

get a low 2 channel amp to power your tweets, wire both 8 ohm tweeters to run 4ohm

get a mid level powered amp 2 channel for your mids wire both 8 ohm speakers to run 4ohm

most 2 channel amps will run at 2 ohms, if you ever need to add more speakers just drop the ohm load to 2 and you will be alright, for example if you add 2 more 8ohm tweeters it will drop the ohm load to 2 channel.

good luck

It's a cap wired into the RCA line it plugs in like a barrel connection on the RCA. There cheap and easy to use

Only thing I disagree with is that many A/B amps don't like running at 2ohm and will get hot and thermal protect. I prefer to use a 4ch bridged and run 2 8ohm mids per side.

Multiple tweeters are a bad idea...

not in pro audio

not in pro audio

There is absolutely no reason for multiple pairs of tweeters in a car.

 

[naughtyca 10+ year member]

apparently you have not been to car shows lately

people do pro audio to get loud, if you want sq then yes 2 tweeters is enough

no reason for Pyle speakers in a car
