I have a Sony MEX-DV1606U installed in my car. I have 2 3-way speakers of 100W, 4 ohms at the rear. I doubt if there is any amp connected to it. I am very new to car audio and amplifiers. I know very less about the stuff. Suggest me a proper amplifier for the pair. What I learnt from the tutorial videos is that the amplifier's output power should be 1.5 times the rated power of speaker. If speakers are of lower power then its okay. And if they are of higher power, then there are chances of distortion and ultimately damage which I would never want. The DVD player has written 52W x 4. That's the thing that worries me.
Whats your budget? whats your car? What is that you want from your Amp (quality of sound/ increase in audio out put), What is your current make of spk in front and back? is this you have bought?
From your description, i assume you are on a tight budget, any way your current set up of spks doesn't warrant any need of an amp, the headset you have is more than enough.Please understand that no AMP in itself give you good sound quality ( if you are an audiophile), it requires a good quality recording, good source( head set) and good spks to go with it.
If you want good sound quality you can get this...( at least a bare minimum for Sound quality)
1. Get Component Car Speakers as front speakers. you can select according to your budget ( it may cost anything from 4K to 9K for an average set up, the choices are bull audio, Jbl, polk audio, alpine, Jl audio, rainbow,focal, infinity,Rockford Fosgate, pioneer etc).
Components will give you a better sound stage and as a general rule front spks should over power the backs ( its not a hard and fast rule though)
2. Damp the front doors using Dyana mat ( or any other damping material, cost can be anywhere between Rs1660/- to 5K)
3. Keep your existing back spks as it is.( It is just as a sound filler)
4. get a 2 channel Amp from JBL and power the front components with the amp. Connet the 2 way back spk directly to the sony DVD system. But if you are planing for a future update to get a sub woofer choose a four channel Amp.
Do not worry about the wattage of your existing 100W 2 way spks instead look for the loudspeaker specification called Continuous Power Handling or Continuous Power Rating. It might be called IEC rating or Power capacity, if it is below 50 W then ur ok. ( this does not apply for your case for th time being----- If you can prevent the power amp from clipping (by using a limiter), use a power amp that supplies 2 to 4 times the speakers continuous power rating per channel. This allows 3 to 6 dB of headroom for peaks in the audio signal. Speakers are built to handle those short-term peaks. If you cant keep the power amp from clipping (say, you have no limiter and the system is overdriven or goes into feedback) the amplifier power should equal the speakers continuous power rating. That way the speaker wont be damaged if the amp clips by overdriving its input. In this case there is no headroom for peaks, so youll have to drive the speaker at less than its full rated power if you want to avoid distortion..) All most all the amps out their can kill your puny 2 way spks in back. The mentioned 100 W is their Max out put, no spk run in their Max out put, even if they runs you cant enjoy it. I don't even for a second suggest you to connect you 100w 2 way to any AMPs, please do not do it. You will be disappointed if you do it.
the next thing is that your selection of head unit. Its bad and nowhere near optimal quality, If you can sell off the sony system and buy a pioneer or FH-X759BT | or alpine head units with 2/3 RCA pre outs) it would be better.
you can get further info fro here
well suggest one. please share the link. and if you say so that my rear speakers would overpower my front ones then suggest a pair of front speakers. planning to replace them.
