    Default Wiring Help for SR5250

    I am very new to car audio and have tried to read up on wiring options for the SR5250 but I am still a little confused. I have a pair of SR5250s in the front stage and I am going to power them with a Kenwood KAC-X40, rated at 4x70 rms. Would it be better to bi-amp these speakers, using a separate channel for each mid and tweet, or will that be too much power? I will be using the passive crossover for now. Thanks in advance.

    70 watts would not be too much. I think most people on here are using more power than that. I ran as much as 150 watts to each tweeter and driver with an active crossover and the speakers were fine. (Oddly enough, I blew my SR tweeters when running them passively).

    If the option is there, biamp.

    Since you are new to car audio I would run the SR5250's with a nice two channel amp and use the existing crossovers. The crossovers will do some additional processing that will help you dial in the sound you are looking for. If you do have to run the 4 channel kenwood amp then I would just run it bridged into two channels. Biamp is available with the Kenwood and using the crossovers that come with the components but That will open you up to additional settings with regard to level control. Unless you are willing to spent hours tunning just for a little extra then make your life easier and go with a two channel amp and use the single input on the crossovers. The sound will still be amazing.

    Thanks to everyone that has responded.

    I'm a noob, but definitely willing to learn. In the future I may upgrade my amp but right now I spent my money on the speakers so for now I am stuck with the Kenwood. I'm curious what you mean that bridging the amp would require more tuning than running a separate channel to each speaker. If I am going through the passive crossover would it make that much of a difference? Only reason I ask is because according to the specs bridging the amp puts out 2x200 but running a separate channel to each speaker would put down 70 watts to each tweet and woofer. Thanks.

    Biamping opens up more tuning, which is what he was saying. The main difference is you can control how much gain each speaker gets separately. I always have the gains on my tweets lower than the woofers to take away some brightness. That's about the only difference there is, but it can make a huge difference.

    I still recommend biamping through the passive xover if you can. Make sure you know what you're doing when setting the gains though. Its a simple process, but one you need to know.

    Greetings from Norway! :) A little off topic, but may I ask:
    How low should HPF on the SR5250's be? Is 60hz too low for these speakers? Thanks... :D

    Depends on how much power youre putting to them, how loud you turn it up, and what you have in the sub/midbass department.

    I have them powered up 2x 100w RMS and I turn it up good. I use a 12"-sub ;)

    I have mine at 63 with no issues on similar power. Just don't get crazy with volume or bass like Cody says and you should be fine.

    I have mine at 50hz, with about 90watts per driver. No issues. As long as your sub is getting enough watts, crossing a bit lower improves the mid bass clarity.

    If you sometimes like to crank it, like I do, make sure your gains at the amp are set properly. In general, 50-63hz is good. Any higher than 63, and your sub will get boomy and you will have a muddy mid bass / mid range.

    I currently split around 63hz myself. I've read that the SR5250's range is from 60hz - 30k hz? :)
