i want to buy this stereo receiver today ! but have some questions

Zeetah · 02-04-2018, 03:34 PM

i looked around and wanted to buy something inexpensive, is this better and most importantly will it give more power to the stock bose speakers i currently have? and without nav. i was looking at the kenwood kmm bt322u. thanks ahead for your input

If you want single din, the kmm bt322u is ok nothing amazing... but if you spend a little more you can get probably the best single din head units made for sound quality, period... they sound amazing are powerful and bring your music to life.. "a receiver that's built for SQ from the ground up"

Pioneer DEH-80PRS (more affordable version then the P99RS)
https://www.crutchfield.ca/S-DSjuMFw...DEH-80PRS.html

Pioneer DEX-P99RS (pricey but the best for sq u can get)
https://www.crutchfield.com/S-uMxU7E...DEX-P99RS.html

These 2 headunits are the go to if you really want sound quality, they were made ground up specifically for this reason. Although there is allot of tuning that will go into these headunits because they have a built in DPS (Digital signal processor) but once you have your settings adjusted and tuned, it will sound better then anything else you can buy.

You will have to shop around online as some places they will be expensive but i have seen some very good prices from a few other sites

1 left here.. but u can find more.

$1200 and 469$ from my $139 lol. cant afford lol

Mashburn94 · 02-04-2018, 05:27 PM

To answer your question, if you directly wire the radio in, and do not bypass the factory amp, then yes it will give more power to your system. However I would not recommend doing this as a long term solution. This method will simply make your speakers start to distort (breakup, sound muddy etc) much earlier than the stock radio. For me I think the Bose system starts to break up (at my EQ settings) around 18-20 on the volume. Replacing the radio without bypassing the amp will make it louder at lower volume. Which I think would lead to blowing the speakers since they are still lightweight paper cones: if you just want a new radio for added features such as USB/Bluetooth, go for it. If you are wanting to improve the overall sound quality of the system, that is not the way to do it:

Yes changing out the speakers does help the sound quality if you put in quality drivers. But sound quality in itself is subjective to the listener. Sound quality comes mostly from EQ settings, making sure the frequency response doesn’t peak or dip to much etc. the radios listed above are two of the best radios you can buy. They allow for if memory serves me correct 16 bands of EQ per speaker on the 80prs, and 32 bands on the 99. They also allow you to time align each speaker to your listening position, which makes a HUGE difference. (Again, subjective.).

Edit: You can get the 80prs on amazon for around 250. If you don’t have anyone you know to help explain/teach you how to tune the system with a RTA, time align etc, it will not do you much good. You can research yourself and learn allot on the internet, but it can get confusing QUICK.

@Zeetah i understand budget and all so at the end of the day its your money and have to go whats within your budget but all im saying is you can go from a low-end headunit (bt322u) to one of the best headunits out there for an extra $110. Imo the difference you are getting is night and day and for just 110 more is amazing and i'd recommend you jump on it

Zeetah · 02-04-2018, 07:38 PM

ty asus and mashburn, you guys helped a lot

bigaudiofanat · 02-05-2018, 09:09 AM

As stated above, don't bypass the bose amp and run their speakers off the new head unit. First off the tweeter and woofers in the bose system have their own signal coming from the amp. There is no in line crossover to block bass from the head unit so you will in fact blow at least the tweeters out. Also the bose speakers are 8 ohms instead of 4 ohms, this means you wouldn't get 22 watts RMS from the head unit you'd get less.

You will not get more volume from just swapping out the head unit. My recommendation is upgrade the head unit wiring it into the bose amp with the proper harness. Then install new speakers and wire them directly to the head unit in a later date if money is tight.

I may have been completely wrong, but wouldn't the input going into the bose amp be different with an aftermarket unit than the factory radio? I know this was the case in my Civic a few years back, but this is a completely different car.

now im completely lost. i thought buying the kmm-bt322u from crutchfield with there gear package and install guide is all i needed, they never mentioned anything about blowing tweeters and anything else you said about bypassing things that i dont understand, sorry, new to this. i will not be upgrading speakers, i just wanted this head unit because it was cheap and had a few things i wanted to use, like a better located usb location, bluetooth audio streaming and i like how it looked. i thought from what crutch said, it would be a straight and easy install.

Mashburn94 · 02-05-2018, 01:34 PM

The only way you will blow something is if you bypass the amp. Basically speakers are designed to play certain frequencies. to simplify things, smaller drivers play high frequencies, the bigger the driver the lower it plays. (to simply put things.) The Bose amp has crossovers built in. (this is what separates high frequencies from the low.) If a tweeter gets signal that is to low for it to handle, it will blow. If you directly wire the radio in place, without bypassing the amp, it will work, just don't go crazy with the volume. If you bypass the amp, you will need to switch out speakers since the ohm loads of the speakers are so crazy. If you go this route, you might as well get an amp for your speakers since you will have to run new wires anyway.

Unless they make an amp bypass harness, I have not looked into that.

IF you were to bypass the bose amp and wire the bose speakers directly to the head unit. Yes you would blow the tweeters.

If you simply buy the harness and head unit this is integrate into the bose amp and speakers. You won't have to touch the amp or speakers at all.
But doing this is only going to give you better sound quality not necessarily higher volume.

so are you saying if i just use what comes in this package and follow the instruction on the install, and not go too loud on my volume, nothing will blow up and everything will be fine? i wouldnt go louder than my usual with the bose system, i havent been in my car for a couple of months bc of winter and i forgot which number volume i would go upto. if the volume maxness stays the same with the new head unit im fine with that, its loud enough i guess.
