Check the woofer for mids and highs bleeding through to the woofer. If you read the review of the 70W amp, there have been multiple reports of the crossover not working properly. Based on those reviews, I purchased the 100W amp which should be here Thursday. That could cause your sound to be off.

OK, I did all the mods this week and, because the parts came from different sources, I upgraded in stages. Here are the order of upgrades and my thoughts:

The woofer recommended by PinBits: http://tinyurl.com/cov2wdf

This did increase the bass significantly. IMHO, it was too much without an L-Pad to work out a nice balance between the woofer and backbox speakers, even after removing the capacitor on the backbox speaker.

Pyle Blue Label in the backbox: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=267-078

Sounds was better, but the bass still dominated the sound. You will need to remove the grills on the panel to fit these unless you have the ability to make a spacer. I removed the grills. The only downside to this is the blue color if you have anything other than a BIBLE. It's not bad, though. I'll probably try a different set in the backbox since I need to place an additional order and move the Blues over to S-M.

The amplifier recommended by markmon: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-802

I used the more powerful of the two amplifiers markmon recommended. The reason I chose the more expensive of the two is after reading the reviews of the lower end model, a few people had problems with the crossover not working properly. For placement, I simply put it where the coin box goes, which allowed me to wire it all up without clipping zip ties on the cabinet harness and pulling the wires from the main bundle should I ever (doubtful) choose to remove it.

All I can say is WOW! This really brought the audio to life and with both the volume and crossover adjustments, it allows you to dial the sound to your personal taste. I am very pleased with the results! Thank you, markmon!

Quoted from taylor34:

Would you recommend just the amp, or the amp + the new woofer + new backbox speakers?

I just swapped the upgraded woofer back to the factory one to evaluate it for you since I had installed the MCM woofer first. The amp does benefit the factory woofer, but the bass just sounds cleaner and has more punch with the MCM. Whether it's worth the $25 to you is your decision. IMHO, the sound is $25 better in the long run.

The backbox speakers are an improvement ($15), but not nearly as much as the amplifier.

You should also check your wiring. My Yellow/Black wire went to the positive and the Yellow/White wire to the negative on the factory speaker.

It's my understanding that the manual may differ depending on which page you look at.

The amplifier fits perfectly where the coin box goes.

That depends on what's included in the FF kit, but it should not be an issue.

Quoted from BShing:

Has anyone used an amp with the front speakers?

Yes. To my ears, there wasn't any real improvement in sound and wasn't worth the hassle. As a matter of fact, the volume of the back box speakers was slightly lower running them through the amplifier.

PinBits had recommended that particular woofer as a drop in replacement. I was simply saying that I personally didn't like the sound level balance between the new woofer and the backbox speakers and if I were to just add the woofer as recommended by PinBits, I'd add an L-pad to adjust the sound to my liking.

Since I added the amplifier, an L-pad was not necessary since you can adjust the volume and crossover frequency on the amplifier.

Basically, if you're using the recommended amplifier, you don't need the L-pad.
