which is a 4 channel amp and 2 channels are unused

Im looking to install 4 more panasonic speakers and hook up to the amp i already have & get a new amp for the sub

the sub is a 12" 1000w or 1200w panasonic so want a amp for this

any suggestions welcome!!

You will wanna look at RMS figures generally and get an amp that has a little higher power than the speakers (called overhead) so for a 400wrms sub maybe an amp that produces 500wrms or more...this gives a cleaner sound as the amp is working at a lower load.

Best advice stick to good name brands....Alpine, Panasonic, Pioneer, etc

Old fusion amps are good too.....good cheap power.

Ohk what about different channel amps?

which would be best for a sub? or can any be good and just bridge them?

Mono are the best for a sub, but no problem bridging 2 channels into one voice coil. If you have a Dual Voice coil sub you could bridge a 4 channel. Just make sure that either the amp or head unit has a good low pass filter if you go with a full range amp (2/3/4 channel), you dont want your sub playing high frequencies.

Have a chat to my friend Dave at [email protected], tell him Jonno sent you and he'll be able to find something good quality that will suit your set up for a good price.

I've owned that exact amp, best to use it just for speakers/tweeters, doesn't run subs very well. Mono-block amps are generally better suited for subwoofers.
