sound question

as of right now i have 1 10" kaption spl, powered by a 300 watt kaption amp, the speakers are powered by the alpine deck, if i were to put the 300 watt amp to the speakers, and a 500 watt kaption amp to the sub, would the difference in the volume of speakers change much?

Is the existing amp a 2 channel, 4 channel or mono amp? Want a deal on some gear, check out this thread.

If everything was copacetic, yes. I believe that 99.9% of the users on this forum would suggest that you amplify your front speakers.

However, there are some things to consider.
So, first things first.
That Kaption amplifier your powering your subwoofer with needs to be a 2 channel amplifier, at least.
If its not, then that amp will not work on your fronts speakers, as each get its own channel, one for the left, one for the right.

If it is a 2 channel amp, then the next thing we need to determine is how much power it will output to a 4 ohm load. Most speakers for car audio will have a resistance of 4 ohms. There are a few 2 ohm speakers. But I'll assume the ones you're currently using are 4 ohm.
If that amplifier is rated for 300W, it'll either be on a 4 or 2 ohm load. We need the model number of that amp so we can determine all its specs, then go from there.

For now though, lets assume that the amp outputs that 300W at 2 ohm. If your speakers are 4 ohm, the resistance being higher, decreases the output of the amp - usually to half. So now your amp will output 150W, which would be 75W to each speaker. Next, you have to determine what the RMS rating is on your speakers. If your RMS is higher than 60W, then you should have no issues.

Get back to us with the model numbers and I'll find out if this'll work for you or not.

If it doesn't, see what MR2NR has available. I bought a 12" Eclipse sub from him last week. Arrived on Saturday. Built the enclosure, and ready to rock - almost.
