My head unit (a Sony MP70) is okay but I'd like to add an amplifier to my audio setup. Am I better off going for two separate 2-channel amps (one for the front speakers and one for the rear) or just one 4-channel amp ?

I was thinking of getting a 4 channel amp and mounting it underneath one of the front seats. Is this a good place to mount it or will there be problems with heat dissipation. Where have other people mounted their amps ?

Finally, any recomendations for good 4-channel amps ?

Just get a decent amp for the fronts, and run the rears off the head unit.

Shouldn't be any problems, you'll probably want to block off the air vents underneath the seat so you don't blow hot air onto the amp. Always the risk of it getting kicked as well.

What's your budget?

Mounted mine in the boot (on both 4dr and 5dr). Well, when i say boot, i mean on the back of the rear seat, next to the 12 disc multichanger. Still leaves you with boot space. The only downside is that they can get scratched if you arent careful with the things you out in there.

WagonRich,

I've installed some Infinity 6x9's in the rear of my Impreza. These were installed in a previous car hooked up to a 2-channel amp and they definitely sounded better like that than when being driven from the current head unit.

I do still have the 2-channel amp just sitting around so I suppose I could try your suggestion first and see what it sounds like. That way it wouldn't cost me any money at all.

Was only looking to spend about £200 on the amp, so was probably going to try for a second hand one.

Boro,

I fold the back seats down and stick my mountain bike in the car so mounting on the back of seats is probably not ideal for me. In fact, anywhere in the boot is more likely to get bashed than underneath the seats I'd have thought...

YHM Glenn.

Aha, now I see a bit more about your system. I presume you are using the 6x9's to get a bit more low end, and have no sub? If that's the case you'll definatly benefit as you planned by amping both the front and the rears. Don't really follow the 2nd hand market, so I wouldn't be able to recommend anything to you I'm afraid, but if you've already got a 2ch amp I'd just add another amp rather than changing to a 4ch - although the 4ch will be simpler from a cabling perspective, and take up less space.

Spot on. Having 2 amps is just going to take up too much space. I think the single 4-channel amp is the way I'm going to go.

I never used it!. Make me an offer.

darms,

I don't think that 4x30W is powerful enough. I'm looking for something more like 4x75W RMS. Cheers for the offer though.

I've got a phoenix gold 150.4 sitting under the drivers seat, driving front Kenwood dual mag components and infinity 605cs mounted into the parcel shelf. Believe it or not, Halfords were doing a very good deal on this amp - I got it plus the infititys for £230 all in. The amp isn't powerful enough to really do a sub justice, but is more than enough for driving full range speakers IMHO. The amp goes far anough under the seat that it doesn't get kicked with me driving, though it may be exposed if you're "vertically challenged"
