    Amps - more power vs less power

    hi,

    I cleverly ended up with two amps, an Alpine MRH-F254 and a Pioneer
    GM-X354. The Alpine is 25x4 and the Pioneer 35x4. Would the 10W make a noticeable difference? I'm using cheap'ish Sansui 6" 3-ways in front and sony xplod 6x9s at the rear. I can't decide which amp to use.

    Alternatively I could bridge them and run both, the Pioneer in front and the Alpine at the rear. I don't know how helpful that would be though, as my speakers aren't exactly top-end... would there be a noticeable difference between 35W and ~70W at slightly-above-normal listening levels? I'm not out to wake the neighbourhood, I just like my music a little louder than normal.

    Here are stock photos of the amps in case anyone wants to see which ones I'm talking about.

    How lazy are you? Wiring up two amps is more work, and you might not have boot space / space under your seats for two.

    Bridging to get more power might be useful: amps tend to be more linear if you're not driving them close to their maximum ratings, so your sound quality may be a little better. Also, if you decide to run an equaliser later on the extra power will be useful.. and if you decide to change your speakers one day you might save yourself some work in the future if you have more power now.

    Hrmm.. I'm quite a lazy person (aren't we all, ha ha), but if there's enough motivation (like good, good sound), i'll probably do it!

    Space is a concern... I can't decide whether to put the amp in the boot and the carputer under the drivers seat or the other way round. There's a sub amp under the passenger seat so i can't put anything else there.

    If I put the carputer in the boot, i'll have to build a mount to attach it to the boot... more work... hmm... I'll also need a vga and usb extension lead.. more money! Then again, i'll have to get longer speaker cables anyway, although they'll cost less than good vga and usb cables.

    Any compelling reasons to put the carputer in the boot instead of under the seat? One thing though, if it's under the seat, the hard disk will be parallel to the ground, in the boot it'll be on its side. I don't have stiffened suspension though.

    good point about changing speakers - i was thinking about it before... man this is getting to be a verrryyyy expensive exercise!
