View Full Version : Help with alpine components/tweeters

02-09-2014, 06:21 PM
I have 6.5in alpine 610c's in my truck hooked up to a jl audio 300/4 amp and they don't sound right to me. I'm not sure how to explain it but they hurt your ears and not in a good way lol, when I picked up the truck after the shop I stalled it I had to turn my amp gain down to about 1/4 they had it at 1/2 and it was way to loud and it doesn't sound good. I researched what I could and most people say they put their tweets to -3 db with a crossover but my speakers didnt come with a crossover it just has a resistor on the mid speaker apparently. I don't really want to buy cross overs and take apart the doors because that why I got a shop to do it in the first place and now I'm short on money. So here is my question:

1. Is there anything I can do to fix this without buying extra things? Change settings on the amp ( not sure what all the settings do to e honest there's alot on that amp)
2. On the amp there is only a switch between 12db and 24db I have it set to 12 is this what needs to be at -3?
3.is it normal to have to set the gain that low on a speaker amp?
4.could it just be the location of them, they are mounted in the stock location ( the pillars by the windshield)

Thanks in advance!

So if you have one set of components, you have 4 speakers total (two mids and two tweeters). Are all 4 speakers connected to their own channel on your amp? You can accomplish the -3db effect by just turning down the gain on the tweeter channels. You should have two different gain knobs.

Otherwise if they're only connected to two channels, what are you using the other two channels for? (If they're available, I'd suggest connecting them like I said)

Take it back to the shop have them change the settings til you like it.

Sadly only two of the channels on the amp work so the tweets can't have their own channel :(

I can't take it back to the shop I got it installed at because I got it done when I was on vacation back home 1200km away

If I do hve to buy crossovers what would be my best choice

your best choice would be to sell that JL since only two of its 4 channels work... and buy an active capable 4 channel amp and have the tweets on their own channels.

for a quick fix, try covering the tweets with a mesh cloth to see if it reduces the harshness.

I think I would have a hard time selling a amp with only half the channels working lol but ill see if I can try the mesh cloth out and maybe try pointing them differently
