I apologize as I realize the Bose amp to bypass or not to bypass issue has been much discussed on here, but I feel like I've gotten to a specific enough question that I just wanted to post a new thread, as I couldn't be certain I was doing this all right trying to piece together info from varying threads...the 4v output to the amp is my main concern on whether I should go 70-1721 or 70-1725 for the ideal system install.
So I currently have the following gear:
Kenwood Excelon KDC-X701 Head Unit (4V output / 6pre-amp RCA outs)
2 Pioneer TS-A1686R speakers in front
2 Pioneer TS-A1685R speakers in rear
Bose Amp / Sub
Already in-hands from Crutchfield's recommendation:
Metra 70-1721 Harness
SLC-4 Line Output Converter
Though I am reading people's recommendation for the 70-1725 harness, the Crutchfield guy said they would error on the side of caution by using the 70-1721 and SLC-4 as to not burn up the Bose amp/sub with the 4v output that the KDC-X701 provides. Any arguments?
...I really don't want to spend more money on a new rear sub or take up trunk space with a box as I'm mostly content with the stock amp/sub. Or, would the ideal setup be the 70-1725 harness with some sort of resistor installed before the amp to reduce the voltage? Can anyone provide a DIY including parts I'll need if that's the ideal route to go for best audio quality that won't burn the sub? Or is that basically all the SLC-4 is doing anyway?
If I go the 70-1725 route, which of the 6 pre-amp outputs am I connecting the RCA's to on the back of the HU to run to the Bose amp?
Also I may be looking at the Infinity BassLink 8" powered amps to slip under my front seats (if they'll fit) to fill in the bass in the future depending on how this all goes. Anything to keep in mind there? Would I just get RCA splitter adapters to branch the pre-amps out to all 3 subs if I used the Bose sub and then an Infinity BassLink under each front seat? I'm trying to minimize taking up space in my car, so I'm not interested in putting in a new bass/amp/box combo anywhere. I'll go without the extra bass if I can't wedge the Infinities under the seats.
Finally, I will be selling off my Bose HU with the Aux-Input mod that I did here shortly in Los Angeles if anyone is interested...it works well save for the hiss if you charge your phone. I did notch a few holes at the top of the dash cover so that I could run my USB charging and Aux cables up through the dash and out of the top of the HU to my phone that sits in a mount above...not terribly noticeable, but maybe not the cleanest look if you aren't going to run your own cables out of them. Please PM me if you want to buy as to not litter this thread. I will post on here if I sell it, so otherwise it's up for sale.
Thanks
