Default 2 speakers on 1 channel??

If I have an amp with plenty of extra gain, can I put 2 speakers on one channel as long as they have the same wattage rating? I have a four channel amp that powers the front door and sailpanel speakers. I want to install 5.25 speakers in the hatch speaker on the same channel as the door speakers.

Physically yes you can. Do I recommend it not really... First, Ill make an assumption, your speakers are PROBABLY a 4ohm load speaker, right? If your not sure check on the magnet, or the box and it will say something like 4ohm or 2ohm maybe even 8ohm. My guess is 4. You also must confirm the voice coil set up, look on each speaker and verify how many terminals there are. If only one set of positive and negative, that’s a single voice coil (SVC), if two, a dual voice coil (DVC). PROBABLY SVC.

If SVC, the only MODERATELY safe way (which I still don't recommend) is to wire the speakers in an 8ohm load series setup on the channel you want them hooked up to (diagram below).

If DVC let me know and Ill help you with that later.

So, what does it mean to do this? In summary you’re wiring 6 speakers on a 4 channel amp. You can't expect all 6 to play as loud as each other if not wired for the amps intended purpose, right. If you do wire your hatches on one channel and fronts on one channel your running all of those speakers at 8ohm which in easy terms is half as loud as what your sail panels will be playing. I suppose you could fade, but it would be more effective to hook the sails to one channel, the rears to one channel, and the fronts two the front 2 channels. This way you can effectively fade the sound to the back to equal out the volume.

Personally I think the hatches are not necessary because the sound reflection of that rear glass can rattle all sorts of $hi# around back there. It won't improve your sound quality and it won't make you louder. It may put additional stress on your amp (make sure it is warrantied and don't tell the manufacturer how you wired it).

There is one good thing about it though... all of those passengers you carry in the trunk will have sound back there
