Speaker making cracking sound?

[OneBadLSE]

lower the gain till you notice ZERO distortion. aftermarket speakers arent really designed to handle BUNDLES of BASS. Be sure to also match up the RMS of the speaker to the AMP you have. More power DOESNT MEAN better sound.

Besides, Jensen amps are JUNK.

[zoomie]

just as a suggustion try using a diff amp jensens are known for blowing out on 1 side for some reason and they work great until they do that sounds to me you have a blown channel BTW how much did you pay for that amp?
I hope it wasnt like 200 dollars or something lol you can get a nice hifonics for that which is what i would reccomend oh and see if you have a biglots near you , also see if they carry visonic speakers i put a set in my linc and they are plenty loud without an amp. also if i where you id go and get another set of 6x9s pioneers arnt bad ,visoniks,polk audio,mbquart all also make some good speakers some cheap some not so cheap all depends what you want to do. i personally dont run a whole lot of bass through mine when i have a sub in the back.

I knows that, just the single speaker blown situation makes me not want to lower the gain

I purchased it about 2 years or so ago for 110 dollars new. I dont believe a channel is blown because because i swapped outputs form the amp and it did not mess up on another speaker.

You are just like my father Nate. He said the same thing but insisted to add that all i do is drive the car to school and back so whats the point of getting new speakers.

A mang with the right priorities.

I haven't been using the radio in the Ram. Teh exhaust is all the music I need...

i agree with OneBadLSE you have to make sure and lower the gain on the amp......cant have much if any bass on those 6x9's. on my four 6x9's i have it set up for a lot of high frequencies, some medium freq., and close to no low freq...thats what the subs in the trunk are for!!!

[87gtVIC]

Yea i will lower the gain. And on my head unit i have an custom equalizer where i can set mids highs and lows, and everything you could imagine it also has crossover frequencies and such for the sub i have. I definitely gotta re look this but what i really need is an expert to tune my system for me!. But for now i took my fathers and Nates advice and just let it be. It is still very loud at just volume 20.

BTW this is the Head unit i have installed. I really really love it.

I lowered the gain. It helped out a tad. It only makes the horrible sound during a song with heavy bass. I do have a sub woofer installed as well, not one with an external amplifier though but is ran through the head unit. How can I direct more bass to it and take the load off of the rear 6X9's. Listed below is the settings i have on the headunit and where i currently have them set at. If all else fails i would love to have Pete adjust it for me during scottfest.

SW (subwoofer) setting 1: Normal
SW setting 2: 80HZ +4
High Pass Filter: 100HZ
Bass Boost: +1
EQ setting 1: Low +6, Mid +5, High +6
EQ setting 2: Low 80HZ Q1W, Mid 2KHZ Q2W, High 8KHZ Q1W
Loudness: Mid


Frankly i have not one clue on what those settings mean on the EQ number 2 settings.

All help appreciated. Like to get as much bass as i possibly can directed to the sub.

Wait, your 6x9's run off the amp, but the sub is powered by the head unit?? That aint right...

My 6x9's are Kenwood dual cone (not 3 way or 2way, but dual cone - looks like a factory speaker) getting 50 watts RMS from an alpine amp, and I can crank it to uncomfortable levels with no distortion. None of my interior speakers are receiving the lowest frequencies (ones they cant effectively reproduce anyway)
You need to figure out your speakers' frequency response (some provide you with a nice response curve plot) and make sure they arent getting something they cant handle.

I would run all inside speakers off the HU (turn the bass down) and the subs off the amp. You cant power them off the same source, unless its using a 5 channel amp with separate frequency crossover for the sub(s)
Unless maybe your head unit has separate powered outputs just for the sub? Even if so, I doubt any head unit can power a sub very well.
Most head unit EQ settings for a sub only control the non-powered RCA sub outputs, which are meant to provide input to an external amp for the subs.

I also noticed in the specs for your head unit that its pre-amp voltage is 4 volts - I want to say this is high, 'normal' is 2volts IIRC, this means you need to keep the gain below "normal" for it to sound good.

haha I know what you mean. My dad says oh you don't need new rims and 275's, suspention, 3.73's, and duals... you just drive it to high school. Right now I'm in the process of convincing my parents to let me run flowmaster 44 dualies dumped at the axel(also will double as my radio haha). It is my car so in the end it will work out hehe.
... and the more I do to the car, the more my parents ask me if they can drive it

way to go bud hope u get the speakers sorted out, my buddy solved that by adjusting the amp adjusters and stuff... oh btw, I like your ride.

Yea. I have a 4 channel amp. The fronts and the rears are ran off of it. The headunits rear speaker output (i forget if it is the right or left rear) doubles as a subwoofer output by just changing the setting of the rear speakers in the headunits main menu. It pushes 70 watts.

See: Maximum Power Output: 50 watts x 4 channels (or 50 watts x 2 channels at 4 ohms + 70 watts x 1 channel at 2 ohms for subwoofer)
Switchable Rear Channel/Subwoofer Output: The rear speaker outputs can be set to provide full range output with full fading capability, or they can be set to provide non-fading subwoofer (low-pass) output. When the rear speaker outputs are set to subwoofer mode, the rear preamp outputs also switch from full range to subwoofer outputs. When set for subwoofer operation, you can connect the rear speaker leads directly to two small 4-ohm passive subwoofers or a dual voice coil sub with 4-ohm voice coils. If you prefer to use a single 2-ohm subwoofer, you can connect the woofer to one set of speaker leads, leaving the other set of rear leads disconnected. The maximum output provided when a 2-ohm load is connected to one set of leads is 70 watts.

as per my radios specs.

Yea...i dont think i have the paper work on those speakers anymore. I installed them in 2006 before i even started driving while the car was sitting in the backyard so i gotta find another way to see what its comfort zone is.

My headunit has pre amp outs for front rear and sub. I am only using the front and rear because i dont have a 5 channel amp or a separate amp for the sub. The sub is being power off of the head unit. And by adjusting the settings for it on the headunit the subs performance is changing. I just need to know where the right place to change the setting is crossover etc. wise to get all the bass i can to it.

I also noticed in the specs for your head unit that its pre-amp voltage is 4 volts - I want to say this is high, 'normal' is 2volts IIRC, this means you need to keep the gain below "normal" for it to sound good.

Thats good to know because i was all disappointed when i have so much potential with this amp and i am required to set the gain very low so it can be audible.


Any suggestions on how to change the settings i have listed?



Edit i think i see my problem???

I am just confused with that whole paragraph though

I think you are right - that says if you used two sets of RCA cables to keep the 'fade' ability, this means your rear 6x9's are getting the same extra low frequencies and bass boost the sub is, and isn't getting any mid or high range, and is why they sound crappy at high volume, since its running your rear speakers in 'sub mode' too.
Looks like the head unit cant make the rear speaker outputs "sub mode" without making the rear RCA outputs that also. They probably weren't counting on anyone having it set up like yours.

No they obviously werent. MAybe another amplifier will be in my future to finally give those poor 6x9's some rest and let that sub work by itself. Thanks for your help. Some things can get pretty complicated when you have some cheap bastard trying to convince the headunit to do things it don't wanna do.

[85crownHPP]

If you hook up the speakers to the HU and the sub to the amp, it will probably work a lot better.

X2

that is usually the norm...and sounds like the head unit wud be more than enuff of an amp for the normal speakers. Thats how my setup is run.
