GenVibe - Community for Pontiac Vibe Enthusiasts

Well I finally did it...My first mod to my vibe was the installation of 4 Alpine Type S speakers. It went alright, I thought maybe the speakers would be screwed in but NO..rivets so that was just a pita to drill out and then drill new holes to mount them, but alas, it all worked out and they sound really good. A lot clearer than stock, but a surprisingly noticable loss in bass. I'm planning on buying an amp to boost them in the near future (read: when i get money) and I could definitely use a sub, but that'll be a while because I have no source of income as of now haha. What should I look for in an amp to power the 4 door speakers? I really have no idea about any of this kind of stuff and the only reason I installed the speakers myself was because I wired up a friend's car a few weeks ago for "practice" he didnt know I had no clue what I was doing. Anyways, any suggestions as far as amp wattage/channels/ etc would be helpful. The speakers are 250w peak btw Thanks

Don't look at the peak values, look at RMS. Pretty much just find any four channel amplifier that'll fit into your budget and closely matches the RMS values of the speakers.

sweet ill check it out..Thanks!

RMS wattage is 50 watts, but is it ok to run like..60x4 or 75x4? What would be the best/most wattage i could run them at safely?

The rule of thumb is to use the most power that you can afford. You'll blow more speakers with a low power amp that with a high power one. When you overdrive an amp it sends out lots of high frequenciy energy right to the speaker that least handel it (the tweeter) . The best way to do it is to use a seperate amp for each set of speakers (subs, mid-range, and tweeters) with a crossoversending just the frequensies that the amps need to drive the speaker: with the subs getting the most power. That way if you over load an amp it doesn'r affect the other speakers in the system.

S-Types are Coaxials. It'd be really tough for her to use multiple amps in this situation.Yes you can get 60x4 or 75x4, whichever you can afford. Just make sure to get the amp tuned so you won't blow the speakers by over-driving them.

Alright cool, I've been looking at amps and I think I found what I want. Thanks for the help! btw I'm a dude

I'm thinking about the Pioneer GM-6200F amp. It says 60w x 4 at 4 ohms and 75x x 4 at 2 ohms. Should I run it at 2 or 4, or does it matter?

You'd be running at 4 Ohms if you have one speaker per channel, which is what you should do. If you're unfamiliar with car audio, going more complex than that could be problematic.The 60x4 rating should be fine.
