Hello Car Audio Forum Gurus.

I haven't done any Car Audio in years and don't know anything anymore. I bought a pair of db5251's and need a low cost amp.

Something good, but no huge budget ($100.00 or less?). I got a new pair of db5251's from Polk for $79.00 (using 100 Polk bucks).

Suggestions welcome.

Thanks in advance.

    no, not a huge budget, good luck. i think walmart sells amps for $100. who'd want that though. crutchfield actually has 3 amps under 100 rite now. i'd act. if i had 2 choose i'd say RF. but can't beat cadence outlet. cadencesound.com. proly get a 4channel for that price. i want some polk buks

    I know this is 60 more than your budget but they would make those db's sound so good.

    Thanks greg2350 and cadenceclipse.

    Again, I don't know S about car audio, many $ have been spent on the home system, but I don't spend a lot of time in the Jag so I don't want to spend a huge amount there.

    I'm checking out all your suggestions though and appreciate your input. I love this forum....

    Do either of you know anything about this alpine amp: Alpine MRP-F240 ?

    Thanks again.

    BTW, polk sent me an email to take part in a survey one day and gave me the POLK BUCKS for my time.

    The survey was regarding the new look of the website. I told them it looked like they were selling lots of outdoor and HT in a box at first glance. I thought the site examples they showed me were kinda cheesy.
