new system help!

ok, i have installed all new speakers, but left the stock head unit. I put in infinity kappa 693.9i (2ohm) 3-way 6x9"'s in the rear and 52.9i (2ohm) 5.25" 2 ways in the front and disconnected the tweeter. i also have a Sony Xplode 1100w (4ohm) sub and a 1000 watt amp. I have the sub getting input from the rear speakers. Now i believe my impedance must be messed up because it sounds like crap. I know stock i had 10 ohm rears and 8 ohm front speakers since there in series.

First I installed the rear infinity's with the sub and the stock front speaker and tested it out and it sounded freaking awesome, so i only thought installing the front ones would make it even better, but it really sucks. Im not a electrical or speaker wizard, so any help would be appreciated

oh and btw i replaced the rears b/c they were blown and im bout to upload pics

thanks

Is it just the front that sounds bad, or did everything start to sound bad after the front speakers were installed?

everything started to sound bad

What do you mean by bad? Distorted , unbalanced , muffled?

muffled and unbalanced, the bass from the rear went away and it wasnt as loud as before when i cranked up the volume

in the morning i think im gonna switch back the fronts and make sure everything is hooked up right again

Sounds to me like one or both of the front speakers are wired out of phase. If you fade to the rear does the bass come back?

If you wired 2 ohm speakers to all 4 channels, it is pulling too much current from the stock head. Can you listen at very low volume okay? Did it sound bad right away when you hooked up the Infinitys, or did it sound okay for any amount of time with the Infinitys installed?

Try disconnecting 2 of the 4 speakers and see if any improvement. Try disconnecting the sub from the rear channels to see if Infinitys work by themselves.

Are you driving the speakers directly off the head? My fronts sounded like crap when I did that until I hooked the stock tweeters back up. Now that they are driven off the amp (well, and I have a different head unit), the front tweeters are disconnected and everything sounds fine.'

I would try running 2 speakers at a time until you get more detail about this mystery.

Yes I am driving the speakers all off the head unit, and it got bad immediately when i installed the front door speakers. im going to take yall's advice and see what i come up with. thanks for your help

by disconnecting the front two it actually sounds better, i think im going to try splicing the tweeter into the speakers to see if that helps. Also by me installing a new head unit, will this solve the problems. If so, i was thinking about a screen, has this been done on the 95's?

New head units typically have better amps than stock, can handle varietys of speaker combinations better, have subout or other built in RCA outs with crossovers etc, I'm all for it. I don't know what's been done on '95s but the stereos aren't that much different than the '98. Take a look at my thread https://rivperformance.editboard.com/audio-electronics-f7/help-me-pick-a-new-head-unit-and-speakers-please-t3812.htm

I agree with deekster and recommend a new head unit. A new radio will make your speakers sound 10x better than with the stock radio because of the better amp and it will be set up for the correct resistance of the speakers. They should also have a pre-amp output so you can hook up an amp to power your sub. The radio will barely make enough power to use the sub. Most after market radios put out about 50 watts peak power per channel and a sub needs a lot more to power it effectively and it will be worse if you are using the stock head unit and splicing the power off the rear speakers as well. You can pick up a good radio for about $100 and I think best buy will install the radio free of labor charges if it is over $100 if you are not comfortably with doing it yourself.

He's already using an amp to power the sub, so that's not really a concern. Splicing into the rears doesn't hurt anything because it's only using a small amount of power to feed the amp.

The stock head isn't that powerful, but it should be able to power four 4 ohm speakers ok. Maggot, what happens when you only hook up the 2 fronts (disconnect sub and 6x9s)?

the fronts sound better AA when i disconnect the rears. As i have it now, the stock tweeter is hooked up front in series so the front should be pulling 6 ohms and my rear sub is hooked up in parallel so the rears should be pulling 3 ohms i think. The system sound better after i wired in the tweeter, but still not up to my standards. im going to look for a new head unit this week and we will see what happens. Thx guys for all your help

Problem: can't use series wiring to drive the stock tweeter and front aftermarkets, because the tweeters use a filtering cap. If you leave the cap inline, all sound will be highs. If you remove cap, you may kill the stock tweeter. Advice: leave stock tweeter disconnected. Use aftermarket 4 ohm speakers instead of 2 ohm.

The powered sub should not affect the load because the amp inputs are very high impedance. No problem driving the sub with rear channels. It's the 2 ohm 6x9s that are giving you the problem. Solution: use 4 ohm 6x9s instead of 2 ohm.

An aftermarket head may solve the problem, but using 4 ohm speakers you could keep the stock head AND still use the sub. If you get an aftermarket head, make sure it is rated to drive 2 ohm loads, or you'll have the same problem all over again.

k thanks, Hey i just looked up my speakers on the website and this is what they say
"• True Four Ohms— All Kappa speakers feature two ohm voice coils. Original factory-installed speaker wiring in many cars is 18-22 gauge. This wire, and heating in the voice coil when power is applied, increase the impedance “seen” by the amplifier or head unit. The impedance of Kappa Speakers has been adjusted to compensate for this increase and can be safely driven by any head unit. "

I realy dont know what this means

They're saying that by the time you factor in the resistance of the speaker wire, you have 4 ohms instead of 2. They may be right, but using that logic, all 4 ohm speakers are actually 6. No matter what the case, those 2 ohm speakers are going to suck more power from your head unit than 4 ohm versions, making it run hotter (and in your case, creating distortion).
