    Car audio noob looking for advice vphoenixgold

    I had a local shop install some new components up front, and a set of coax in the rear of my truck. They sound okay running off the head unit, but from what I've learned, amping will make them sound 100 times better...so with that..

    I have installed Phoenix Gold ti65cs up front and ti65cx in the back.

    I need an amp for those guys. Front is RMS 125 peak 250 and the back is RMS 75 peak 150 4 ohms

    Thoughts?!?

    I already have two JL 10's in under the seats running of their own amp.

    Idk what the impedances are of those speakers, but if they're anything like your average set of components you will want something like this

    Amazon.com: MB Quart ONX4.125 1000W RMS, ONYX Series 4-Channel Amplifier: Car Electronics

    SD500.4 - 500 Watt 4 Channel Amplifier - Phoenix Gold

    Thoughts?

    reason? Everything distorts right now at about 33 of 50 on my setup now....Won't the rears continue to do the same?

    Not necessarily. What kind of sound are you going for? I was just thinking of ways to try and save you money. A lot of people only amp their front stage. I have my front and rears amped, but I also have a sedan. What you could do is get a 4 channel amp, try only amping the front stage and see how that works. If your rear stage keeps distorting then throw them on the rear channels of the amp. If not then use all 4 channel on your front stage and create an active crossover network.

    Go with this option here and I'm sure you will be happy, you will have plenty of headroom and the volume that you are looking for without having to turn the radio up as loud. Most people here will tell you to buy something online and install it yourself but I say if you are not up to it then stay with the shop that you've built a relationship with and see how they take care of you.

    I for sure can tell you I won't be installing it myself. I'll pay the money, that I don't care too much about. Right now, with the speakers distorting, I'm hoping its because they are under powered. It has to be, right?

    I'm also getting greedy with the bass...I'm likely to up the amp on the subs and also buy new subs in the future. I plan to jack the truck up, so I can't have a ****** stereo!!

    Amp both sets, cross the rears low. Bandpass the rears 80hz-200hz.
    Get amps that do more rms than your speakers, to ensure no distortion.
    It'll sound good.

    Make sure you cross all your speakers correctly or they'll sound like poop. I'm assuming you have crossovers for you're comps which will do the crossing over for you, but bandpass the rears like I mentioned.



    "When I listen to a stereo loudspeaker playback in my room and an auditory scene has formed in my mind, how would I know that what I hear is an accurate replica of an auditory scene that could be had at the recording venue? Or more generally, that this is an auditory scene that could have existed at all?"

    I'm unsure of what bandpass refers to.
    also, do you recommend an amp for those speakers?

    Bandpass is a type/way of filtering.
    High pass filter blocks frequencies below the set frequency.
    Low pass filter block frequencies higer than the set frequency.
    Bandpass filter is a frequency range you want the speakers to play, and will block frequencies below and above that range.

    The reason I recommend 80-200hz is because if you have high frequencies playing on the rear speakers, those sounds will interfere with the sounds the speakers in the front play, and will cause interferece, which sounds like distortion and changes the sound of your music.
    Ive also found that low frequencies played on rear speakers sound good amped, and blend fairly well without being distractive or messing up the sound.

    And yes, amp the rears in my opinion, or else there wouldn't be a point in having them there.

    If I go with that amp, I plan to buy from the shop. I have an amp for the subs under my passenger seat that I want moved to the back wall with the new amp. So with that, they need to re wire for 4 gauge wiring, distribution block, and all the other stuff. $600ish with the amp.

    This statement is not exactly accurate, having highs in the rear will not cause this to happen. What I think he is trying to say is that it may pull your sound stage more to the rear of the vehicle, but again if done properly that wouldn't be an issue either. I've built and listened to many vehicles with mids and highs in the rear that had a very solid front stage.....

    Also any shop worth it's salt should know how to setup the rear speakers properly for you.
