I recently got infinities on my 97accord. they got 300w on the rear and 270 in the front and I got a old AIWA with only 180 watts. When i put the bass up and the volume up the rear speakers bass sounds distorted. I have assed around and everyone has there ideas. Some say its because i have a weak head unit and others say is because i need a amp. So i need to know what can i do to clean up the sound. If its the head unit how many watts and if its the amp how many watts? Thanks for your help!

They basically say the same thing. There is also an opinion that you are asking too much from your hu in terms of sound quality boost.

If you want, wait a few days and I will tell you what exactly an amp will do. I have the same problem as you. Have 4 new Polk speakers, pioneer hu and it distorts (lower frequencies) when I boost it. The amplifier just came in today. My wiring kit should be here in a few days. I played so far a lot with different settings without the amp, so I'll know for sure what kind of a difference it makes.

 

I know this is going to be an overly simple way of looking at it, but here goes.

The headunit, although rated at 180, is probably only pushing out about 70 watts of clean power. As you get louder the distortion increases.
Since the speakers are rated at a higher wattage, and you have a measily 70 watts pushing on them you have to crank it higher just to hear it.

70 into 300 is pretty weak. Imagine trying to push some big home speakers with a little 100 watt receiver, they play, but not even close to their full potential, or volume.

Get an amp. Hook it up, call it a day.

 

yeah i plan to get a amp! and yeah 300 in the rear and 270 in the front is max. You maybe right about the speakers not being sealed because the rear speakers are the ones i am having trouble with not the front. In the rear I could only put in 2 screws and the speakers is like 3mm to big to fit the other 2 screws. How do i put the other 2 screws in?

 

Tell me the difference it made in your system. thanks

 

oh and another thing the distortion comes from the bass at high volumes

 

You better have your speakers mounted very tight! You can get a lot of distortion that comes not out of your speaker, but simply your speaker is hitting the mount that produces a distortion-like sound. 2 screws could be enough...but to make sure, hold your 1 speaker with your hands (while it's mounted) and if some of the distortion goes away, then you definitely need more screws. You can try to drill new holes, to get the other 2 screws in. But first check if you really need it. It might be ok anyway.

 

Thanks

1- mount speaker to absolutely flat surface ,[ bending or twisting speaker is very bad]

2- airtight seal between front and back of speaker for the diameter of the speaker from the outside edge of the speaker all the way around [ eg- a 5" speaker should be airtight for 5" from the edge of the speaker all the way around the speaker

3- mass, the more mass the speaker is mounted to the better it will sound.

also a speaker mounted to wood will sound better then a speaker mounted to just about anything else.

You may need to make a trim ring for the rear speakers. 94

 

how do u make a rear trim for the rear speakers

MDF?

A little too simple, lol. The headunit's claim of 180watts is PEAK, and therefore its putting out 45x4 PEAK watts, aka 17 (MAX) RMS of power - which is NOTHING. You need an amp because you're turning your music up wayyy too high and your **** is clipping. Also, don't expect spectacular sound from coaxials anyway - the tweeter mounted on a woofer causes more distortortion, midbass what not.

Get a decent component set in the front powered by an amp and forget about the rear fill.

i dont have any subs on my car

 

so how powerful a head unit i need? and how powerful a amp i need? and are there any brands you recommend over others?

 

Headunit power does not matter. If you are going with a sub you are going to use a headunit preamp out.

A nice 2x160 would be a good start.

 

no i am not getting subs. I just have a 45x4 head unit and 300 watt rear speakers and 270 watt front speakers with the independent tweaker in the front. How many watts should the amp be to clear up the distortion.

 

I just want it to be clear and the bass to be clean.

how about this. The speakers in the front have not given me any problems so it must be the rear ones not getting enough power. I got this 4 channel amp that will push ,90 max power watts, to the rear, will that be enough to clear the distortion?
Sorry if i keep asking simple questions I dont know anything about systems.
