Hi all

I have been looking to get an amp to drive the speakers in my car as it sounds great at low volumes buts runs out of puff quite quickly.

I am currently running a Sony MEX BT3800U Headunit with 2x Edge ED204 10cm 3 way coaxials in the front and 2x Vibe 69.3 3 way 6x9's in the boot in enclosures.
Now as i said this sounds ace at low - medium volumes but runs out when i really try to crank it up such as when i am driving with windows open in this damned heat

I was originally after a 4 channel amp and the 3 i was looking at are
Edge ED7800 £89.99
Fli 900s £89.99
Vibe Slick A1 £112
I was mostly intersted in the Vibe as it looks quite rugged and appears to have good reviews.

HOWEVER

Upon having a look around at amps i have stumbled upon this ebay listing which has thrown a spanner in the works as it looks like a bloomin bargain

http://www.ebay.co.uk/itm/FLI-Loade...ent_GPS_Car_Amplifiers_PP&hash=item3a686a8361

A brand new FLI 450s 2 channel amp for £38 delivered, now i was thinking get 2 of these (1 under each front seat) and use one to drive the fronts and one to drive the rears.

The reason i was looking at a 4 channel amp rather than a 2 channel was so i could set up crossovers and have all the Bass going to the 6x9's in the boot and very little Bass heading to the tiny edges in the front so i can hopefully get serious volume without much distortion.

Now the question is am i better paying a bit more and getting a 4 channel amp, or will the 2 cheaper 2 channels be adequate. Or even better could i get away with just amping up the 6x9's and leaving the fronts running off the head unit therefore only requiring 1 of the 2 channel amps.

I mean if i want to send bass only to the 6x9's the Headunit has a single subwoofer out RCA which can be split and feed the both channels of the amp and then i can use the internal high pass filter to filter the bass to the front speakers, but this idea may sound crap so thats why i am asking someone with a bit of ICE experience as i am new to all of this.

I am looking forward to hearing suggestions, the cheaper the better really as i am on a budget.

Thanks in advance for any replies

Amp everything, running fronts off the headunits internal amp means your giving them around 12w RMS.....thats never enough.

As for your query about the amp(s) setup.....If you run two 2 channel amps you can still run the x-overs as you would on a single 4 channel, however your going to have to run 2 lots of power wire, two remote wires and two earth cables, or fit a distribution block. Fitting a single four channel would save space and require less wiring.

Also you haven't said what your head unit is. How many pre-outs have you got?

The head unit is a Sony MEX BT3800U which has 3 pre outs 1 stereo front and 1 stereo rear, and a mono sub output.

Yeah I was thinking about the 4 channel being easier to mount and wire up so I will most likely do that option. mount the whole thing on a peice of mdf under the drivers seat.
