I have a 2003 Lightning with the stock six CD head. Awhile back I decided to buy Boston Acoustics SL80 speakers to replace all four of the cheap stock speakers. After I put them in I noticed how clean the sound was but I was now lacking bass. I wanted something simple to install so I ordered a MTX Thunderform amplified subwoofer enclosure to give me a little more bass. My question is will my new system sound alright like this, or should I order another amplifier to power the Boston SL80 speakers? I'm not into super loud or super bass, I just want to have a nice full sound.
