5ch Amp Question: bridge or not

[clayparkley]

I'm almost finished with vert stereo install.
I want to know if I should bridge 4ch of 5ch amp to power the front and power the rear with HU or just use the amp to power all.
Here's the list of what I have.

Built-in Speaker PowerMOSFET 50W x 4
Continuous Power Output22W x 4


Amp: Boston Acoustics GTA-1105
5-channel car amplifier
70 watts RMS x 4 + 250 watts RMS at 4 ohms
125 watts RMS x 4 + 400 watts RMS at 2 ohms
250 watts RMS x 2 bridged output at 4 ohms + 400 watts RMS at 2 ohms


Front: Alpine SPR-50C
100 Watts RMS
300 Watts Peak


Rear: Pioneer TS-G1344R
220 Watts Max Power (35 Watts Nominal)


Sub: 2x KICKER Comp 8-Inch Subwoofer 4 Ohm

Pls let me know your opinion and why. Thanks in advance.

OK, simple answer: deck power sucks.

In your case, you might wanna try it just because you would only have to change what, 8 wires?

Here is the real deal though: you can't adjust it. You will be limited by the rear speaker gain settings if you use deck power. You also only have a couple of choices about what high pass settings you can use, while that amp has continuously variable high pass.

Besides, bridging that amp will only give you maybe 1db more volume, as the Alpines will piss themselves if you try to feed them that much.

How is the install going? Got pics yet?

Thanks for the info Luke.
Install is going very well. I couldn't take any pics. I'm doing very little at a time on my lunch break at work :D since I have three little boys to take care at home. Right now, I'm saving some money for the sound deadening material. Cutting holes is pretty much all I have left to do now, but my drill(Black&Deck 12v) is just too weak to do the job. I'm gonna have to find someone to lend me one. I'll try to get some photos and post it as I finish this up.
