Hey,
That was good information and thanks but I have my own doubts regarding the set-up and its drawbacks.
- When the Amp itself is 2 channel to support 4 speakers, How will that actually cause a load to the amp and hence drain the battery when it is designed to support 4? Moreover, The speakers used are within the output limits specified by the Amp. Please share more.
A 4 Ch amp will power 4 speakers well. but don’t add a sub on it. again this is in theory- my setup worked on by a unskilled installer initially, had connected 4 speakers and a sub on my poor a604. I used it for a yrs and finally got fed up with the sound imbalance and bal dominated by the rear 6x9". so I had a reputed installer, upgrade the entire wiring and setting. even through this cost me more than the initial install cost, it is worth it knowing that the amp is working in safe zone and the sound is perfectly balanced and tuned.
-I agree that connecting a SW would put more load (when 4 is the limit) Agreed
-Why cant the the Aux-out connectors on the Amp, used to connect additional amp be connected to the front Aux-Ins when the output itself is non-amplified and simply gets connected as Inputs for the fronts (which would otherwise come from the RCA Pre-outs of the HU itself, and In my case, It wasnt available). Anyways, the same input will be amplified to produce output for the front. I too am using a Pio 2050 with only 1 set of RCA. in the same boat as you, literally, the initial installer in Milan, had connected it the same way. but the explanation I got from the knowledgeable installer is that the wire should not be looped that way as using the aux out to the Rca in the same amp, heats up the system on high volume and prolonged usage. the solution is pretty cheap, a pair of y splitters that cost Rs.150. leave the aux out for future upgrade to mono or a second amp.
I have been using this set-up since pretty long now (2 years) and haven’t faced any issues of overheating or other unlisted ones. I too used it for a yr but the sound balance was dominated by the rear speakers, really bugged me.
I too was doubtful that the setup - amp for 2 front speakers and sub, and HU to rear 2 speakers. but this really sounds good and you can control the balance from the HU - front 2 or back 2.
Initially when I purchased the system the installer simply connected the SW only, leaving the amp hardly utilized even when the support was for 4 speakers and the bass of the SW (with the lowest setting) was taking precedence over the regular Front and Rears connected directed to the HU. I chose to change this setting myself and It has worked fine for me. 4 speaker on the head unit and amp only for the sub .
With my spouse and mom as rear seat passengers, I usually disconnect the SW and the sound quality is crisp with the 4 speaker set-up. With the amp for 2 front speakers and sub, and HU to rear 2 speakers, you can control only the front speakers to work, i.e.- back speaker and sub will be dead, and this setting is through the HU, big benefit here.
However, I will look into a few threads/posts to see for the problems and if they were caused due to this set-up or by using differently rated speakers. Reply in bold. |
